  •       TEXAS COURT OF APPEALS, THIRD DISTRICT, AT AUSTIN
    NO. 03-04-00027-CV
    Anadarko E&P Company, L.P. f/k/a RME Petroleum Company;
    Larry T. Long, Sammy Adamson and L. Allan Long, in their Capacities
    as Trustees for the Lawrence Allan Long Trust, Charles Edward Long Trust,

    v.
    Railroad Commission of Texas; Anadarko E&P Company, L.P.
    f/k/a RME Petroleum Company, Appellees
    FROM THE DISTRICT COURT OF TRAVIS COUNTY, 200TH JUDICIAL DISTRICT
    NO. GN204461, HONORABLE LORA J. LIVINGSTON, JUDGE PRESIDING
    MEMORANDUM OPINION
    This administrative appeal involves a challenge to a final order issued by the
    Texas Railroad Commission granting a well-spacing exception under Statewide Rule 371 to appellant
    Anadarko E&P Company, L.P. f/k/a RME Petroleum Company. On appeal, Anadarko raises
    several procedural challenges to the Commission’s final order, and appellants Larry T. Long,
    Sammy Adamson, and L. Allan Long, in their capacities as trustees for the Lawrence Allan Long
    Trust, Charles Edward Long Trust, Larry Thomas Long Trust, and John Stephen Long Trust
    (collectively the “Long Trusts”), argue that the Commission’s order was not supported by substantial
    1
    16 Tex. Admin. Code § 3.37 (2008) (Tex. R.R. Comm’n, Statewide Spacing Rule)
    (“Rule 37”). Because the relevant portions of Rule 37 have not changed during the pendency of this
    appeal, we cite to the current rule for convenience unless otherwise noted.
    evidence. Because we find no merit in Anadarko’s procedural challenges and we conclude the
    Commission’s final order was supported by substantial evidence, we affirm the district court’s
    judgment affirming the Commission’s order.
    BACKGROUND
    The Commission issued a final order granting a permit for the Barksdale Well No. 8
    on September 12, 2002.2 Commission staff had previously granted a permit for Well No. 8 to
    Anadarko’s predecessor, which was challenged by the Long Trusts for lack of notice. In its final
    order, the Commission determined that the original permit, granted administratively by Commission
    staff without protest, was void ab initio because the Long Trusts failed to receive notice of the permit
    application in accordance with Commission rules. Upon proper notice and hearing, the Commission
    granted an exception to the spacing requirements under Rule 37 to prevent waste and issued a new
    permit for Well No. 8.
    The Original Permit
    Anadarko’s predecessor UPRC applied to the Commission for a permit to drill
    Well No. 8 in 1997. As part of its application, UPRC requested a Rule 37 exception and submitted
    a conditional waiver of objection from Sonat Exploration. The plat attached to UPRC’s application
    erroneously identified the offset leaseholder and operator as Sonat Exploration, instead of the
    Long Trusts. Given the conditional nature of the waiver executed by Sonat Exploration, the
    2
    The Commission issued a nunc pro tunc order on November 13, 2002, correcting two
    clerical errors in its previous order.
    2
    Commission sent notice of UPRC’s Rule 37 application to Sonat Exploration on January 9, 1998.
    The Commission received no objection to UPRC’s application within the requisite ten-day time
    period and, therefore, Commission staff granted UPRC an administrative Rule 37 exception as
    allowed under subsection (h)(2)(A). See 16 Tex. Admin. Code § 3.37(h)(2)(A). In the absence of
    an objection, the Commission did not hold a hearing or receive evidence regarding UPRC’s
    application. UPRC completed the well in June 1998 after receiving approval of its Rule 37
    application from Commission staff.
    The Long Trusts’ Complaint
    On May 23, 2001, the Long Trusts filed a complaint with the Commission on the
    ground that they failed to receive notice of UPRC’s application for a Rule 37 exception for
    Well No. 8. The Commission set the matter for hearing and conducted an administrative hearing on
    the complaint. During the hearing, the Commission also considered whether the well was entitled
    to a Rule 37 exception.
    Because no one disputed that the Long Trusts were entitled to receive notice
    under Rule 37 and UPRC had failed to give notice of its application for a Rule 37 exception to the
    Long Trusts, a major focus of the administrative hearing was whether the original permit was void
    or voidable. Anadarko argued that the permit was merely voidable because evidence was submitted
    that the Long Trusts had actual knowledge of the proposed location for Well No. 8 before it was
    drilled. The Long Trusts are a working interest owner in Well No. 8 and, in this capacity, UPRC
    sent the Long Trusts an approval for expenditure (“AFE”) with well location plats showing that the
    proposed location for Well No. 8 would require a Rule 37 exception. The Long Trusts signed the
    3
    AFE in March 1998. Thus, Anadarko argued that the Long Trusts’ signing of the AFE demonstrated
    actual knowledge of UPRC’s application for a Rule 37 exception and, therefore, cured any defect
    in notice. However, like the plat submitted with UPRC’s application to the Commission, the plat
    sent to the Long Trusts failed to identify the Long Trusts as the offset operator to the west of the
    portion of the unit where Well No. 8 was drilled.
    The hearings examiners issued a proposal for decision recommending that the original
    permit be declared voidable, not void, because the Long Trusts had actual knowledge of the proposed
    well location and did not file a timely complaint with the Commission. The hearings examiners
    further recommended that the Commission grant a Rule 37 exception for Well No. 8 on the basis
    that the well is necessary to prevent waste.
    The Commission considered the proposal for decision in a public conference on
    September 12, 2002, and rejected the hearings examiners’ recommendation in part. Contrary to
    the recommendation, the Commission voted to declare the permit void ab initio because the Long
    Trusts did not receive notice of UPRC’s application as required by the plain language of Rule 37.
    The Commission adopted the examiners’ recommendation to grant a Rule 37 exception for Well
    No. 8 to prevent waste. Those commissioners who were present signed a final order.
    Although representatives of the Long Trusts were present at the Commission’s public
    conference on September 12, 2002, they were not given a copy of the Commission’s signed order.
    The record reflects that later that day Commission staff faxed a courtesy copy of the order to the
    attorneys for Anadarko and the Long Trusts. The next day, September 13, 2002, the Commission
    mailed a cover letter and a copy of the final order to the attorneys of record in the administrative
    4
    proceeding. The attorney for the Long Trusts received the cover letter and final order on Monday,
    September 16, 2002.
    Motions for Rehearing
    Anadarko filed its motion for rehearing on October 2, 2002. That same day, after
    receiving Anadarko’s motion for rehearing, the Long Trusts filed a letter with the Commission
    requesting that the Commission revise its final order and deny the Rule 37 exception. Two days
    later, on October 4, 2002, the Long Trusts filed a formal document specifically labeled as its motion
    for rehearing. Like the letter filed on October 2nd, the October 4th motion asked the Commission
    to reconsider its final order and deny the Rule 37 exception. Relying upon the date it mailed the
    copies of the final order, the Commission considered both Anadarko’s motion for rehearing and the
    Long Trusts’ motion for rehearing filed on October 4th to be timely filed.
    Nunc Pro Tunc Order
    On November 13, 2002, the Commission denied the parties’ motions for rehearing
    and issued a nunc pro tunc order correcting two clerical errors in its previous order. The
    Commission corrected the year of the hearing from “2002” to “2001” and, based on the evidence in
    the record, the Commission corrected the year that the Long Trusts learned about Well No. 8 from
    “1988” to “1998.” Following the issuance of this nunc pro tunc order, Anadarko filed a second
    motion for rehearing. The hearings examiners advised the parties by letter that the nunc pro tunc
    order corrected only clerical errors and that the Commission no longer had jurisdiction to act on the
    matter. The Commission therefore took no action on Anadarko’s second motion for rehearing.
    5
    Appeals in District Court
    Anadarko and the Long Trusts filed separate appeals from the Commission’s
    final order issued September 12, 2002. The district court signed an agreed order consolidating the
    two appeals. Thereafter, the district court entered final judgment affirming the Commission’s
    final order.3 Anadarko and the Long Trusts appeal the district court’s final judgment affirming the
    Commission’s final order.
    DISCUSSION
    On appeal, Anadarko raises nine issues. In general, Anadarko faults the Commission
    for declaring the original permit void, not voidable, and for considering what it views as an untimely
    motion for rehearing filed by the Long Trusts. For their part, the Long Trusts challenge the merits
    of the Commission’s order arguing that the Commission applied the wrong legal standard in granting
    a Rule 37 exception and that the Commission’s order was not supported by substantial evidence.
    Standard of Review
    We review the Commission’s final order under the substantial evidence rule. See
    Tex. Gov’t Code Ann. § 2001.174 (West 2008). Under the substantial evidence rule, we give
    significant deference to the agency in its field of expertise. Railroad Comm’n v. Torch Operating
    Co., 
    912 S.W.2d 790
    , 792 (Tex. 1995); Texas Health Facilities Comm’n v. Charter Med.-Dallas,
    Inc., 
    665 S.W.2d 446
    , 452 (Tex. 1984). We presume that the agency’s order is valid and that
    3
    The district court also signed an order denying Anadarko’s plea to the jurisdiction and,
    thereafter, entered findings of fact and conclusions of law regarding its denial of the plea. The
    parties do not appeal from the district court’s denial of Anadarko’s plea to the jurisdiction.
    6
    its findings, inferences, conclusions, and decisions are supported by substantial evidence. City of
    El Paso v. Public Util. Comm’n, 
    883 S.W.2d 179
    , 185 (Tex. 1994); Charter 
    Med., 665 S.W.2d at 452
    . The complaining party has the burden to overcome this presumption. City of El 
    Paso, 883 S.W.2d at 185
    ; Hammack v. Public Util. Comm’n, 
    131 S.W.3d 713
    , 725 (Tex. App.—Austin
    2004, pet. denied).
    In conducting a substantial evidence review, we may not substitute our judgment
    for that of the agency on the weight of the evidence on questions committed to the agency’s
    discretion. Tex. Gov’t Code Ann. § 2001.174; Charter 
    Med., 665 S.W.2d at 452
    ; H.G. Sledge, Inc.
    v. Prospective Inv. & Trading Co., Ltd., 
    36 S.W.3d 597
    , 602 (Tex. App.—Austin 2000, pet. denied).
    The issue for the reviewing court is not whether we believe the agency’s decision was correct,
    but whether the record demonstrates some reasonable basis for the agency’s action. Charter 
    Med., 665 S.W.2d at 452
    ; Central Power & Light Co. v. Public Util. Comm’n, 
    36 S.W.3d 547
    , 561
    (Tex. App.—Austin 2000, pet. denied). We will uphold the agency’s order unless the agency’s
    decision is not reasonably supported by substantial evidence, in violation of a constitutional or
    statutory provision, in excess of the agency’s statutory authority, made through unlawful procedure,
    affected by other error of law, arbitrary or capricious, or characterized by an abuse of discretion. See
    Tex. Gov’t Code Ann. § 2001.174(2)(A)-(F).
    Certain issues raised by the parties involve questions of statutory construction, which
    we review de novo. See, e.g., City of San Antonio v. City of Boerne, 
    111 S.W.3d 22
    , 25 (Tex. 2003)
    (appellate courts review matters of statutory construction de novo); In re Humphreys, 
    880 S.W.2d 402
    , 404 (Tex. 1994) (questions of law are always subject to de novo review). When construing
    7
    a statute, our primary goal is to determine and give effect to the legislature’s intent. City of
    San 
    Antonio, 111 S.W.3d at 25
    . To determine legislative intent, we look to the statute as a whole,
    as opposed to isolated provisions. State v. Gonzalez, 
    82 S.W.3d 322
    , 327 (Tex. 2002). We begin
    with the plain language of the statute at issue and apply its common meaning. City of San 
    Antonio, 111 S.W.3d at 25
    . Where the statutory text is unambiguous, we adopt a construction supported
    by the statute’s plain language, unless that construction would lead to an absurd result. Fleming
    Foods of Tex., Inc. v. Rylander, 
    6 S.W.3d 278
    , 284 (Tex. 1999). We give serious consideration to
    an agency’s interpretation of the statutes it is charged with enforcing, so long as that interpretation
    is reasonable and consistent with the statutory language. Tarrant Appraisal Dist. v. Moore,
    
    845 S.W.2d 820
    , 823 (Tex. 1993); Steering Comms. for the Cities Served by TXU Elec. v. PUC,
    
    42 S.W.3d 296
    , 300 (Tex. App.—Austin 2001, no pet.). This is particularly true when the statute
    involves a complex subject matter. Steering Comms. for 
    Cities, 42 S.W.3d at 300
    . Courts, however,
    “do not defer to administrative interpretation in regard to questions which do not lie within
    administrative expertise, or deal with a nontechnical question of law.” Rylander v. Fisher Controls
    Int’l, Inc., 
    45 S.W.3d 291
    , 302 (Tex. App.—Austin 2001, no pet.).
    Additionally, certain issues raised by the parties challenge the Commission’s
    authority. The Texas Railroad Commission “is a creature of the Legislature and has no inherent
    authority.” Public Util. Comm’n v. GTE-SW Corp., 
    901 S.W.2d 401
    , 407 (Tex. 1995). Like other
    state administrative agencies, the Commission “has only those powers that the Legislature expressly
    confers upon it” and “any implied powers that are necessary to carry out the express responsibilities
    given to it by the Legislature.” Public Util. Comm’n v. City Pub. Serv. Bd., 
    53 S.W.3d 310
    , 316
    8
    (Tex. 2001). It is not enough that the power claimed by the Commission be reasonably useful
    to the Commission in discharging its duties; the power must be either expressly conferred or
    necessarily implied by statute. The agency may not “exercise what is effectively a new power, or
    a power contradictory to the statute, on the theory that such a power is expedient for administrative
    purposes.” 
    Id. Statutory Scheme
    and Rule 37
    We provide a brief overview of the relevant statutory scheme to give context to
    the parties’ arguments. The legislature has given the Commission exclusive jurisdiction to regulate
    oil and gas wells in Texas. See Tex. Nat. Res. Code Ann. § 81.051(a)(2) (West 2001).4 Pursuant
    to this authority, the Commission has adopted various rules regarding the drilling and spacing
    of oil and gas wells in Texas, including Rule 37—the Statewide Spacing Rule. See generally
    16 Tex. Admin. Code §§ 3.1-.106 (2008). In relevant part, Rule 37 provides:
    No well for oil, gas, or geothermal resource shall hereafter be drilled nearer than
    1,200 feet to any well completed in or drilling to the same horizon on the same tract
    or farm, and no well shall be drilled nearer than 467 feet to any property line, lease
    line, or subdivision line; provided the commission in order to prevent waste or to
    prevent the confiscation of property, may grant exceptions to permit drilling within
    shorter distances.
    16 Tex. Admin. Code § 3.37. Rule 37 further provides that when an exception to the spacing
    requirements is desired, the applicant shall file an application with the proper fees and attachments
    4
    Section 81.051 of the natural resources code provides in relevant part: “The commission
    has jurisdiction over all . . . oil and gas wells in Texas.” Tex. Nat. Res. Code Ann. § 81.051(a)(2)
    (West 2001).
    9
    as prescribed by the rule. 
    Id. § 3.37(a)(2).
    The application must include a plat that conforms to
    the requirements in subsection (c) of Rule 37. 
    Id. § 3.37(c).
    In addition, the applicant must file a
    list of the mailing addresses of all affected persons as identified in subsection (a)(2)(A) of the rule.
    
    Id. § 3.37(a)(2)(A).
    The purpose of this list is to allow the Commission to give notice of the
    application to all affected persons. See Tex. Nat. Res. Code Ann. § 85.205 (West 2001) (requiring
    the Commission to provide notice and an opportunity for hearing). Rule 37 also requires a person
    acquainted with the facts pertinent to the application to certify that all facts stated in the application
    are true and within the knowledge of that person. 16 Tex. Admin. Code § 3.37(a)(2).
    Commission staff may grant an administrative approval of an application for
    exception if notice of at least ten days has been given and no protest has been filed or written waivers
    of objection are received from all persons to whom notice would be given under the rule. 
    Id. § 3.37(h)(2).
    If a protest is filed, the Commission will hold a hearing on the application for
    exception. See Tex. Nat. Res. Code Ann. § 85.205; 16 Tex. Admin. Code § 3.37(a)(3).
    Anadarko’s Claims
    Challenges to Commission Authority
    We turn first to Anadarko’s claims that the Commission erred in declaring the initial
    permit void. In its second, third, fourth, and fifth issues, Anadarko challenges the Commission’s
    authority to reconsider the issuance of the original permit on the grounds that: the proceeding was
    an impermissible collateral attack on a final Commission order; the Commission lacks authority
    to review the order granting the original permit; and, even if the Commission could review the
    final order granting the permit, the Commission erred in failing to consider and give effect to the
    10
    equitable defenses of laches, estoppel, waiver, and ratification, and, therefore, the Commission erred
    in declaring the permit void and not voidable.
    We reject Anadarko’s argument that the Commission proceeding was an
    impermissible collateral attack on a final Commission order. Both the Texas Supreme Court and
    this Court have recognized that the Commission has statutory authority in certain circumstances to
    reconsider its prior orders in oil and gas matters. See Magnolia Petroleum Co. v. New Process Prod.
    Co., 
    104 S.W.2d 1106
    , 1110-11 (Tex. 1937); Sexton v. Mount Olivet Cemetery Ass’n, 
    720 S.W.2d 129
    , 139 & n.5 (Tex. App.—Austin 1986, writ ref’d n.r.e.) (discussing power of railroad commission
    to reconsider prior orders and citing Magnolia Petroleum Co. v. New Process Prod. 
    Co., supra
    ;
    Railroad Comm’n v. Aluminum Co. of Am. (“ALCOA”), 
    380 S.W.2d 599
    , 602 (Tex. 1964) (holding
    commission may modify proration orders “where conditions have changed materially, new and
    unforeseen problems arise or mistakes are discovered.”)). In Magnolia Petroleum Co., the supreme
    court considered whether the Commission had authority to reconsider its previous denial of a
    Rule 37 exception and held that, although the Commission was without authority to review or set
    aside judicial decrees, the Commission had authority to reconsider its own orders upon a showing
    of changed circumstances. Magnolia Petroleum 
    Co., 104 S.W.2d at 1110
    . In Railroad Commission
    v. ALCOA, the supreme court confirmed that “the Commission’s power to regulate oil and gas
    production in the interest of conservation and protection of correlative rights is a continuing one
    and its orders are subject to change or modification where . . . mistakes are 
    discovered.” 380 S.W.2d at 602
    (emphasis added). In Sexton v. Mount Olivet Cemetery Association, this Court discussed the
    Commission’s authority to reconsider its prior orders in light of the supreme court’s holdings in
    11
    Magnolia Petroleum 
    Co., supra
    and 
    ALCOA, supra
    , and concluded that the statutes administered
    by the railroad commission granted the Commission the power to set aside its previous orders in oil
    and gas 
    matters. 720 S.W.2d at 139
    & n.5. This Court explained:
    In each of these decisions, the statute involved (Tex. Rev. Civ. Stat. Ann. art. 6049c,
    §§ 5, 7, now codified as Tex. Nat. Res. Code §§ 85.049-.053, 85.058-.064 (1978))
    almost amounted to an express delegation to the Commission of a power to
    reconsider its previous orders in oil and gas matters, for it directed the Commission,
    on complaint or on its own “initiative,” to inquire “from time to time” into any aspect
    of the oil and gas business to determine, after hearing, whether “waste” was
    occurring or was imminent and to issue whatever “rule, regulation or order” may be
    “reasonably required to correct, prevent or lessen such waste.”
    
    Id. The statutes
    in question have not changed. Section 81.051 of the natural resources
    code grants the Commission exclusive jurisdiction over oil and gas wells in Texas. Tex. Nat. Res.
    Code Ann. § 81.051. Section 85.201 authorizes the Commission to make and enforce rules
    and orders for the conservation of oil and gas, the prevention of waste of oil and gas, and,
    correspondingly, the protection of correlative rights. 
    Id. § 85.201
    (West 2001); see 
    Sexton, 720 S.W.2d at 139
    n.5. In addition, section 85.058 gives the Commission authority to inquire
    “whether the oil and gas conservation laws of this state or the rules and orders of the [C]ommission
    promulgated under those laws are being violated.” 
    Id. § 85.058
    (West 2001). And section 81.053
    gives the Commission express authority to “hear and determine complaints.” 
    Id. § 81.053
    (West 2001). Furthermore, section 85.205 serves the constitutional and legislative objective of
    protecting correlative rights by requiring that no Commission rule or order may be adopted without
    “notice or hearing as provided by law.” 
    Id. § 85.205.
    12
    The Commission proceeding at issue involved a hearing and determination of the
    Long Trusts’ complaint that the administrative approval granted by Commission staff was granted
    in violation of the Commission’s rules regarding oil and gas conservation, the prevention of waste,
    and protection of correlative rights—in particular that the Long Trusts were deprived of “notice and
    hearing as provided by law” under Rule 37. Based on the precedents of both the supreme court and
    this Court interpreting the Commission’s statutory authority, we conclude that the Commission, in
    the absence of judicial review of its prior order, has statutory authority to reconsider its prior
    administrative order granting the original Rule 37 exception to UPRC.5 See Magnolia Petroleum
    
    Co., 104 S.W.2d at 1110
    ; 
    ALCOA, 380 S.W.2d at 602
    ; 
    Sexton, 720 S.W.2d at 139
    & n.5. We further
    conclude that the proceeding was not an impermissible collateral attack on a final Commission order
    and that the Commission acted within its statutory authority to consider the Long Trusts’ complaint.6
    We overrule Anadarko’s second and third issues.
    5
    We emphasize that our holding today does not stand for the general proposition that
    an administrative agency has the inherent authority to reconsider its prior adjudicative orders. See
    Sexton v. Mount Olivet Cemetery Ass’n, 
    720 S.W.2d 129
    , 139 & n.5 (Tex. App.—Austin 1986,
    writ ref’d n.r.e.). Whether an agency possesses such authority must be considered in light of
    the statute that vests the agency with administrative power. 
    Id. at 138
    (agencies have no inherent
    authority).
    6
    To the extent Anadarko relies on Sproles Motor Freight Line v. Smith, 
    130 S.W.2d 1087
    (Tex. Civ. App.—Austin 1939, writ ref’d), and Public Utility Commission v. Brazos Electric Power
    Cooperative, 
    723 S.W.2d 171
    (Tex. App.—Austin 1986, writ ref’d n.r.e.), in support of its claim
    that the Commission lacks authority to review its prior orders, we find those cases distinguishable.
    Unlike the Commission’s authority in this case, Sproles did not involve the Commission’s authority
    in oil and gas matters, but instead concerned the granting of an application for a certificate
    of convenience and necessity to operate motor trucks as a common carrier on Texas 
    highways. 130 S.W.2d at 1087
    . Similarly, Brazos Electric Power Cooperative involved an entirely different
    agency—namely, the public utility commission, not the railroad commission—and thus an entirely
    different 
    statute. 723 S.W.2d at 173
    .
    13
    In its fourth issue, Anadarko complains that the Commission erred in declaring
    the original permit void rather than merely voidable. Anadarko is concerned with what it terms
    the retroactive effect of the Commission’s permit revocation—i.e., that its production under the
    original permit was illegal from its inception. Anadarko frames this argument in jurisdictional terms.
    According to Anadarko, because the original permit was valid on its face and the lack of notice to
    the Long Trusts was not a jurisdictional defect, the permit was merely “voidable”—i.e., its
    revocation was effective prospectively—not “void.” We find these arguments to be without merit.
    We first observe that in Magnolia Petroleum 
    Co., supra
    , the supreme court held that
    a Commission order entered without proper motion, notice, and hearing was 
    “void.” 104 S.W.2d at 1106
    . In that case, New Process Production Company filed an application to drill three additional
    wells on a mineral lease in Gregg County, Texas. 
    Id. at 1107.
    The Commission, after notice of
    the application was duly given, denied the request. 
    Id. Thereafter, New
    Process again consulted
    the Commission about drilling the additional wells. 
    Id. The company
    presented the matter to the
    Commission “without any motion, additional application, or notices,” and the Commission, without
    hearing, entered a second order granting the application. 
    Id. Because the
    Commission’s second
    order was entered “without any motion, additional application, or notices,” the supreme court
    cancelled, annulled, and declared void the Commission’s second order granting the application. 
    Id. In Railroad
    Commission v. McKnight, the supreme court confirmed its holding in Magnolia
    Petroleum Co. “that the [second] order was void, not because the [C]ommisson was without
    potential jurisdiction to enter it but because it was entered without proper motion, notice and
    hearing.” 
    619 S.W.2d 255
    , 258 (Tex. 1981).
    14
    As previously noted, section 85.205 expressly limits the Commission’s authority by
    prohibiting it from adopting a rule or permit “except after notice and hearing as provided by law.”
    Tex. Nat. Res. Code Ann. § 85.205. There is no dispute that the Long Trusts were entitled to notice
    under Rule 37. Rule 37 provides that “[n]o well drilled in violation of this section without special
    permit obtained, issued, or granted in the manner prescribed in said section . . . shall be permitted
    to produce.” 16 Tex. Admin. Code § 3.37(e) (emphasis added). In the absence of proper notice, we
    conclude that the Commission did not err in declaring the original permit “void”—i.e., the
    production was illegal from its inception—rather than “voidable.” See Magnolia Petroleum 
    Co., 104 S.W.2d at 1107
    ; 
    McKnight, 619 S.W.2d at 258
    ; see also Rodriguez v. Service Lloyds Ins. Co.,
    
    997 S.W.2d 248
    , 254 (Tex. 1999) (courts defer to an agency’s interpretation of its own rules unless
    plainly erroneous or inconsistent with the regulation or underlying statute). We overrule Anadarko’s
    fourth issue.
    We similarly reject Anadarko’s complaint that the Commission erred in failing to
    consider and give effect to the equitable defenses of laches, estoppel, waiver, and ratification.7 The
    record is clear that the Commission considered and rejected the equitable arguments raised by
    Anadarko. The Commission specifically rejected Anadarko’s defense of laches when it refused to
    7
    Anadarko relies on the statements of a commissioner at the conference in which the
    Commission considered the proposal for decision in asserting that the Commission failed to consider
    Anadarko’s equitable defenses. However, it is immaterial what the commissioners may have said in
    the process of arriving at a decision. See City of Frisco v. Texas Water Rights Comm’n, 
    579 S.W.2d 66
    , 72 (Tex. Civ. App.—Austin 1979, writ ref’d n.r.e.). Statements of a commissioner made during
    the deliberative process in an open meeting are irrelevant to the judicial determination whether the
    agency order is reasonably sustained by appropriate findings and conclusions that have support in
    the evidence. 
    Id. 15 adopt
    the hearings examiners’ recommendation and proposal for decision on this issue. Likewise,
    the Commission rejected the remaining arguments asserted by Anadarko when it considered and
    denied Anadarko’s motion for rehearing. Because the record demonstrates that the Commission
    considered and rejected the equitable defenses raised by Anadarko, we consider only whether the
    Commission erred in failing to give effect to these defenses.
    This Court has recognized that an administrative agency makes fundamental policy
    choices when it adopts rules under the APA rulemaking procedures. Texas Ass’n of Long Distance
    Tel Co. (Texaltel) v. Public Util. Comm’n, 
    798 S.W.2d 875
    , 886 (Tex. App.—Austin 1990,
    writ denied). Such policy choices necessarily involve the balancing of competing interests and an
    evaluation of the equities of the situation. 
    Id. The Commission’s
    adoption of notice requirements
    thus represents a fundamental policy choice that proper notice is required before the Commission
    or its staff may grant a Rule 37 exception. See 16 Tex. Admin. Code § 3.37(a)(2)(A) (requiring
    notice), (h)(2) (prohibiting administrative grant of Rule 37 exception unless notice has been given
    and no protest has been filed or written waivers of objection are received). Furthermore, as
    previously noted, this notice requirement has both constitutional and statutory underpinnings.
    We cannot conclude that the Commission erred with regard to the weight it afforded
    UPRC’s “equitable” factors as against the interests in strict enforcement of Rule 37’s notice
    requirements. See 
    Rodriguez, 997 S.W.2d at 255
    (agency is bound to follow its own rules and
    procedures); Public Util. Comm’n v. Gulf States Util. Co., 
    809 S.W.2d 201
    , 207 (Tex. 1991) (same).
    We overrule Anadarko’s fifth issue.
    16
    Notice
    In its first and sixth issues, Anadarko argues that the Long Trusts’ actual knowledge
    of the well location and the Commission’s subsequent hearing and finding that the permit is
    necessary to prevent waste satisfied the notice requirements in Rule 37 or, alternatively, cured any
    defect in notice. We disagree.
    Having adopted the notice requirements in Rule 37, the Commission was entitled to
    insist upon strict compliance with its rule. See 
    Rodriguez, 997 S.W.2d at 255
    (agency is bound to
    follow its rules); Gulf States Utils. 
    Co., 809 S.W.2d at 207
    (same); see also F.A. Gillespie & Sons
    Co. v. Railroad Comm’n, 
    161 S.W.2d 159
    , 163 (Tex. 1942) (“An operator’s rights must be acquired
    in compliance with the provisions of a valid rule of the Commission; and none can be acquired in
    violation of it.”). As previously suggested, that the Commission requires strict compliance with the
    notice requirements of Rule 37 is consistent with the statutory scheme and structure of the rule. The
    natural resources code prohibits the Commission from adopting an order or rule pertaining to the
    conservation or waste prevention of oil and gas “except after notice and hearing as provided by law.”
    Tex. Nat. Res. Code Ann. § 85.205. The plain language of Rule 37 places the burden of correctly
    identifying affected persons squarely upon the applicant. 16 Tex. Admin. Code § 3.37(a)(2). It is
    therefore incumbent upon the applicant for a Rule 37 exception to ensure that the correct parties have
    been identified so that the Commission may provide proper notice to those parties. 
    Id. We agree
    with Anadarko, and the Commission found, that the Long Trusts had actual
    knowledge of the proposed location of Well No. 8. But actual knowledge of the proposed location
    does not equate to actual knowledge of UPRC’s application for a Rule 37 exception. Nor does it
    17
    equate to the notice that the Long Trusts were entitled to receive in order to allow them an
    opportunity to protest that application.
    The AFE submitted to the Long Trusts identified the Long Trusts as a 25% working
    interest owner in the proposed well. But the plat attached to the AFE failed to identify the
    Long Trusts as the affected offset operator of the adjacent tract. Even if we assume, based solely on
    the proposed location of the well as identified in the plat, that the Long Trusts knew a Rule 37
    exception would be required, we cannot assume the Long Trusts knew they were the offset operator
    and were therefore entitled to protest such an exception.
    While we agree with Anadarko that the Long Trusts had actual knowledge of
    the proposed location of Well No. 8, we do not agree that such knowledge satisfied the notice
    requirements of Rule 37. The notice requirements of Rule 37 are designed to protect the correlative
    rights of those parties affected by a Rule 37 exception. The mere knowledge of a well’s proposed
    location without more does not protect correlative rights because it does not give notice of
    any potential adverse effects to such rights. Therefore, we conclude that the Long Trusts’ actual
    knowledge of the proposed location of Well No. 8 neither satisfies the requirements of Rule 37 nor
    cures any defect in notice. We likewise conclude that the Commission’s subsequent hearing on
    the Long Trusts’ complaint cannot cure the defects in notice regarding the original permit
    application. See, e.g., In re Adoption of Armstrong, 
    394 S.W.2d 552
    , 555-56 (Tex. App.—El Paso
    1965) (on remand, adopting opinion of U.S. Supreme Court in Armstrong v. Manzo, 
    380 U.S. 545
    (1965) (subsequent hearing does not cure due process defect regarding lack of notice of original
    proceeding)). We overrule Anadarko’s first and sixth issues.
    18
    Final Order and Motions for Rehearing
    In its three remaining issues, Anadarko challenges the district court’s determinations
    that the November 13, 2002, nunc pro tunc order of the Commission was not a final order and brings
    two challenges to the Long Trusts’ motions for rehearing. We reject these claims.
    The record demonstrates that the Commission issued its final order on September 12,
    2002. Thereafter, on November 13, 2002, the Commission issued an order nunc pro tunc to
    correct two clerical errors in its previous order. The Commission’s order nunc pro tunc corrected
    the hearing date from “December 12, 13, and 14, 2002” to “December 12, 13, and 14, 2001” and also
    corrected another date from “March 1988” to “March 1998.”
    In its seventh issue, Anadarko contends that the district court erred in holding that the
    November 13, 2002, order nunc pro tunc was not a final order. The essence of Anadarko’s argument
    is that the Long Trusts were required to file a second motion for rehearing from the November 13,
    2002, order nunc pro tunc in order to preserve their complaints on appeal, and the Long Trusts failed
    to do so. Therefore, according to Anadarko, the district court should have dismissed the Long
    Trusts’ administrative appeal for lack of jurisdiction. We disagree.
    In support of this argument, Anadarko relies primarily upon section 2001.145 of
    the Administrative Procedure Act (“APA”), which requires a timely motion for rehearing as a
    prerequisite to an appeal in a contested case. See Tex. Gov’t Code Ann. § 2001.145(a) (West 2008).
    Both the Texas Supreme Court and this Court have previously rejected this argument. In Consumers
    Water, Inc. v. Public Utility Commission, the supreme court held that a second motion for rehearing
    was not required when the agency’s subsequent order denied the parties’ motions for rehearing,
    19
    but amended the previous order to add the finding of “imminent peril” required under
    subsection 2001.144(a)(3) of the APA. 
    741 S.W.2d 348
    , 349 (Tex. 1987). Significant to our
    analysis here, the supreme court reversed this Court’s judgment and holding that a second motion
    for rehearing was required. See 
    id. (reversing Consumers
    Water, Inc. v. Public Util. Comm’n,
    
    707 S.W.2d 186
    (Tex. App.—Austin 1986)).
    The supreme court has since confirmed that reviewing courts should use a “more
    pragmatic and flexible approach” to evaluate the finality of an agency’s order. Texas-New Mexico
    Power Co. v. Texas Indus. Energy Consumers, 
    806 S.W.2d 230
    , 232 (Tex. 1991). Under this
    approach, courts must recognize the need to minimize disruption of the administrative process and
    to afford regulated parties and consumers with an opportunity for timely judicial review of actions
    that affect them. 
    Id. The supreme
    court explained that “there is no single rule dispositive of all
    questions of finality, and reviewing courts should consider the statutory and constitutional context
    in which the agency operates, and should treat as final a decision ‘which is definitive, promulgated
    in a formal manner and one with which the agency expects compliance.’” 
    Id. (quoting 5
    J. Stein,
    G. Mitchell & B. Mezines, Administrative Law 48-10 (1988)).
    Applying the supreme court’s “more pragmatic and flexible approach,” this Court, in
    Office of Public Utility Counsel v. Public Utility Commission, held that a second motion for
    rehearing was not required when the subsequent orders of the administrative agency did not
    alter the original order with respect to the first motion for rehearing. 
    843 S.W.2d 718
    , 726
    (Tex. App.—Austin 1992, writ denied). In other words, where the agency’s subsequent order did
    20
    not grant the motion for rehearing or otherwise change the previous order in response to a motion
    for rehearing, this Court determined that there was no need for a second motion for rehearing. 
    Id. To the
    extent Anadarko relies on this Court’s decision in Southern Union Gas Co.
    v. Railroad Commission, 
    690 S.W.2d 946
    , 948 (Tex. App.—Austin 1985, writ ref’d n.r.e.), we find
    that case distinguishable. In that case, the Commission granted the gas company’s motion for
    rehearing for the limited purpose of changing the effective date to implement new rates and, thereby,
    modified its earlier order. The Commission denied the motion for rehearing in all other respects.
    The gas company did not file a second motion for rehearing. 
    Id. at 947.
    This Court determined
    that Southern Union Gas was required to file a second motion for rehearing after the Commission
    modified its earlier order. 
    Id. at 948.
    This Court rejected the argument that a second motion
    was unnecessary because the modification of the earlier order was not substantial. 
    Id. at 948-49;
    see
    Ross v. Texas Catastrophe Prop. Ins. Ass’n, 
    770 S.W.2d 641
    , 644 (Tex. App.—Austin 1989,
    no writ) (to draw distinction between order that agency changes substantially in response to motion
    for rehearing and one that changes only in minor fashion is not the law of this state).
    In this case, unlike Southern Union Gas, the Commission denied the motions for
    rehearing. Like Office of Public Utility Counsel, there was no change in the Commission’s order
    with respect to the Long Trusts’ motion for rehearing. Therefore, we conclude that the Long Trusts
    were not required to file a second motion for rehearing from the Commission’s November 13, 2002,
    order nunc pro tunc.8 We overrule Anadarko’s seventh issue.
    8
    We observe that this distinction is consistent with other cases cited by Anadarko. See
    Railroad Comm’n v. Exxon Corp., 
    640 S.W.2d 343
    , 346 (Tex. App.—Beaumont 1982, writ ref’d
    n.r.e.); Mahon v. Vandygriff, 
    578 S.W.2d 144
    , 146-47 (Tex. Civ. App.—Austin 1979, writ ref’d
    21
    In its eighth and ninth issues, Anadarko challenges the sufficiency and timeliness
    of the Long Trusts’ motions for rehearing. Anadarko first argues that the Long Trusts’ letter filed
    October 2, 2002, was not a proper motion for rehearing and, therefore, preserved nothing for review.
    Second, Anadarko argues that the Long Trusts’ motion for rehearing filed October 4, 2002,
    was untimely because the APA requires a motion for rehearing to be filed within twenty days after
    a party receives notice of the Commission’s final order and the Long Trusts received a copy of
    the Commission’s final order on the day it was signed, September 12, 2002, thereby making the
    applicable twenty-day deadline October 2nd and rendering the October 4th motion untimely.
    Because we conclude the Long Trusts’ October 4th motion for rehearing was timely
    filed, we do not consider Anadarko’s argument regarding the sufficiency of the October 2nd letter
    filed by the Long Trusts.
    As previously noted, section 2001.145 of the APA requires a party to file a timely
    motion for rehearing as a prerequisite for judicial review. Tex. Gov’t Code Ann. § 2001.145(a).
    Section 2001.146 specifies that a party must file its motion for rehearing not later than the
    twentieth day after the date on which the party or the party’s attorney of record is notified as
    required under section 2001.142. 
    Id. § 2001.146(a)
    (West 2008); Temple Indep. Sch. Dist.
    v. English, 
    896 S.W.2d 167
    , 169 (Tex. 1995). Under subsection 2001.142(a), a party shall be
    n.r.e.). In Exxon Corp., the agency granted the motion for rehearing and the reviewing court held
    that a second motion for rehearing was thus 
    required. 640 S.W.2d at 345-46
    . In Mahon, the initial
    agency order was contingent upon future events and, therefore, was not a final 
    order. 578 S.W.2d at 147
    . The agency issued two subsequent orders, and the appellant did not file a motion for
    rehearing regarding either of these orders. 
    Id. at 146.
    On review, this Court affirmed the trial court’s
    dismissal for failure to file a motion for rehearing from the agency’s final order. 
    Id. at 147-48.
    22
    notified either personally or by first class mail of any decision or order. Tex. Gov’t Code Ann.
    § 2001.142(a) (West 2008). The APA thus provides two methods by which a party or the party’s
    attorney can be notified of an agency’s decision: personal notice or notice by first class mail. 
    Id. In this
    case, the record reflects that the Long Trusts did not receive a copy of the
    Commission’s order at the public conference on September 12, 2002. Although Commission staff
    faxed a courtesy copy of the order to the Long Trusts’ later that day, this faxed copy does not satisfy
    the APA requirement of personal notice or notice by first class mail. See Tex. Gov’t Code Ann.
    § 2001.142(a). The record reflects that Commission staff mailed a copy of the order to the
    Long Trusts’ attorney of record the next day—September 13, 2002—and that the Long Trusts’
    attorney of record received this mailed notice on September 16, 2002. It is this mailed notice that
    satisfies the requirements in section 2001.142(a) of the APA. See 
    id. Therefore, the
    deadline for
    filing a motion for rehearing was twenty days from September 16, 2002, or October 6, 2002.
    Tex. Gov’t Code Ann. § 2001.146(a). Because the Long Trusts’ motion for rehearing was filed
    October 4th, we conclude the motion was timely, and we overrule Anadarko’s ninth issue. We now
    turn to the merits of the Long Trusts’ claims.
    The Long Trusts’ Claims
    In two issues, the Long Trusts contend that the Commission erred in granting a
    Rule 37 exception to Anadarko’s predecessor in interest UPRC. First, the Long Trusts argue that
    the Commission applied the wrong legal standard and, second, the Long Trusts argue that the
    Commission’s order was not supported by substantial evidence.
    23
    Anadarko and the Commission assert that the Long Trusts have failed to preserve
    their complaint that the Commission applied the wrong legal standard by failing to raise this issue
    in their motion for rehearing. Alternatively, Anadarko and the Commission argue that even if we
    conclude the issue has been raised, the Long Trusts’ complaint is more properly considered in the
    context of whether the Commission’s order is supported by substantial evidence because the essence
    of the Long Trusts’ argument is that the Commission applied the wrong law to the facts of this case.
    Having reviewed the Long Trusts’ October 4th motion for rehearing, we disagree with Anadarko and
    the Commission that the Long Trusts have failed to preserve this issue. However, we agree that the
    essence of the Long Trusts’ complaint is that the Commission applied the wrong law to the facts of
    this case and that this argument is more properly considered in the context of whether the
    Commission’s order is supported by substantial evidence, which we address more fully below.
    In their second issue, the Long Trusts argue that the Commission’s order granting a
    Rule 37 exception is not supported by substantial evidence. Essentially, the Long Trusts argue
    that Anadarko failed to establish that Well No. 8 was necessary to prevent waste. For the reasons
    discussed below, we reject the Long Trusts’ argument.
    Rule 37 allows the Commission to grant an exception to the spacing requirements
    thereunder on two grounds: to prevent waste and to prevent the confiscation of property. 16 Tex.
    Admin. Code § 3.37(a)(3). The Commission’s final order granted UPRC a Rule 37 exception on the
    ground that Well No. 8 was necessary to prevent waste.
    The supreme court has defined the term “waste,” as used in Rule 37, to mean “the
    ultimate loss of oil.” Gulf Land Co. v. Atlantic Ritchfield Co., 
    131 S.W.2d 73
    , 80 (Tex. 1939).
    24
    Under this definition, the court explained that a Rule 37 exception to prevent waste may be justified
    if a substantial amount of oil or gas that otherwise would ultimately be lost will be saved by
    the drilling of a well. 
    Id. (emphasis added).
    To obtain a Rule 37 exception to prevent waste, it must
    be shown that, because of unusual conditions in the localized area, closer spacing of wells is
    necessary to recover the hydrocarbons. Wrather v. Humble Oil & Ref. Co., 
    214 S.W.2d 112
    ,
    117 (Tex. 1948). Thus, to obtain a Rule 37 exception, UPRC was required to show that unusual
    conditions—i.e., different from conditions in adjacent parts of the field—existed under the tract for
    which the exception was sought; that as a result of these unusual conditions, hydrocarbons cannot
    be recovered by any existing well or by additional wells drilled at “regular” locations;9 and that the
    volume of otherwise unrecoverable hydrocarbons is substantial.
    The record demonstrates that the Barksdale Estate Gas Unit on which Well No. 8 is
    located is an irregularly shaped unit with a panhandle section similar to the shape of the State of
    Texas or Oklahoma. The well is located in the panhandle section of the unit equidistant from
    east and west lines. Although regular locations exist on the unit, no regular locations exist in the
    panhandle section. The undisputed evidence showed that there was a rapid depositional environment
    in the area of Well No. 8 as contrasted to the remaining field as a whole. The evidence showed that
    this rapid depositional environment would impact the heterogeneity, permeability, and porosity in
    the area of Well No. 8. The Commission determined that the lease geometry of the panhandle
    section coupled with the impact of the rapid depositional environment constituted an unusual
    9
    A “regular” location is a well location that does not require a Rule 37 exception because
    it meets the requirements of the Commission’s statewide spacing rules or the spacing requirements
    in “special field rules” applicable only to a particular field.
    25
    condition that precluded the reservoir from being adequately drained by wells at regular locations.
    In addition, the evidence showed that Well No. 8 will recover between 224 and 1,056 million cubic
    feet of gas that would not otherwise be recoverable by wells at regular locations. The Commission
    thus determined that Well No. 8 would recover a substantial amount of hydrocarbons that would not
    otherwise be recoverable by wells at regular locations.
    The Long Trusts challenge the Commission’s order on the grounds that there was
    conflicting evidence presented on the issue of “unusual conditions” at the location of Well No. 8 and
    that the Commission failed to require UPRC to demonstrate unusual conditions at the site of the
    proposed well. To the extent the Long Trusts argue that certain evidence in the record showed a lack
    of unusual conditions, the Long Trusts ignore the established premise that the Commission was
    entitled to accept or reject in whole or in part the testimony of the various witnesses who testified.
    See City of Corpus Christi v. Public Util. Comm’n, 
    188 S.W.3d 681
    , 695 (Tex. App.—Austin 2005,
    pet. denied); Railroad Comm’n v. Lone Star Gas Co., 
    618 S.W.2d 121
    , 125 (Tex. Civ. App.—Austin
    1981, no writ); City of Frisco v. Texas Water Rights Comm’n, 
    579 S.W.2d 66
    , 69 (Tex. Civ.
    App.—Austin 1979, writ ref’d n.r.e.). Likewise, the Commission was the sole judge of the weight
    to be accorded the witnesses’ testimony. Central Power & Light 
    Co., 36 S.W.3d at 561
    .
    The Commission’s order expressly states in finding-of-fact ten that the “undisputed
    geologic evidence shows that there was a rapid depositional environment in the area of the Barksdale
    No. 8 as contrasted to the field as a whole.” The Commission found that this “rapid depositional
    environment” in conjunction with the lease geometry constituted an unusual condition justifying a
    Rule 37 exception. The record thus demonstrates that the Commission’s decision to grant a Rule 37
    26
    exception was based in part on the unusual condition of a “rapid depositional environment” in the
    localized area of the proposed well. We conclude that there is a reasonable basis in the record
    before us to support the Commission’s finding of unusual conditions at the location of Well No. 8.
    See Charter 
    Med., 665 S.W.2d at 452
    ; Central Power & Light 
    Co., 36 S.W.3d at 561
    .
    The Long Trusts further argue that the Commission’s order was not supported by
    substantial evidence because the Commission’s consideration of “lease geometry” was improper.
    In considering whether to grant a Rule 37 exception to prevent waste, the supreme court has held that
    the Commission need not confine its analysis to the sole question as to whether the well will save
    oil that otherwise would be lost. Gulf Land 
    Co., 131 S.W.2d at 85
    . Rather, “the Commission should
    be left reasonably free to exercise its sound judgment and discretion,” keeping in mind that the
    Commission’s duty is to conserve oil and gas above ground as well as below. 
    Id. Such discretion
    would reasonably include the ability to decide which factors to consider in determining whether
    to grant a Rule 37 exception to prevent waste, as well as how much weight to give each factor. Id.;
    see also Halbouty v. Railroad Comm’n, 
    357 S.W.2d 364
    , 374 (Tex. 1962) (finding Commission, in
    exercising its regulatory discretion, may give greater or less weight to relevant factors in setting
    production limitations); Texas Bldg. Owners & Managers Ass’n v. Public Util. Comm’n, 
    110 S.W.3d 524
    , 536 (Tex. App.—Austin 2003, pet. denied) (when exercising delegated regulatory authority,
    agency has discretion to consider factors legislature may not have foreseen and to decide relevancy
    and weight of those factors in each circumstance).
    That the Commission may consider factors beyond mere geology in determining
    whether requirements necessary to grant a Rule 37 exception to prevent waste have been met was
    27
    more recently confirmed by the supreme court in Exxon Corp. v. Railroad Commission, 
    571 S.W.2d 497
    (Tex. 1978). In that case, the court upheld the Commission’s determination that an existing
    well bore, as well as economic infeasibility of drilling at regular locations, established unusual
    conditions justifying a Rule 37 exception to prevent waste. 
    Id. at 501.
    Citing evidence that the oil
    to be produced from the proposed well could not be produced from any other existing well, the court
    affirmed the Commission’s determination that an exception was necessary to prevent waste. 
    Id. The Commission’s
    consideration of economic infeasibility in Exxon Corp. is no
    different than the Commission’s consideration of lease geometry in this case. We therefore reject
    the Long Trusts’ claim that the Commission was forbidden from considering lease geometry when
    determining whether a Rule 37 exception should have been granted to prevent waste.
    The Long Trusts also argue that the Commission’s order was not supported by
    substantial evidence because the Commission failed to make a finding that no well at a regular
    location would drain the hydrocarbons to be recovered by Well No. 8. Contrary to this assertion, the
    Commission expressly determined in finding of fact 11 that lease geometry coupled with the impact
    of the depositional environment would preclude the panhandle section of the Barksdale Unit from
    being drained “by wells at regular locations.” The record demonstrated that the formation into which
    Well No. 8 was completed was a tight gas formation, which means that gas is not easily produced
    from the reservoir without stimulation. In addition, the evidence submitted by UPRC included a well
    28
    reservoir simulation study showing that Well No. 8 would recover hydrocarbons that would not be
    recovered by a well at a regular location.10 We therefore reject the Long Trusts’ contention.
    Finally, the Long Trusts contend that the Commission erred in considering volumes
    of gas that had been illegally produced since 1998 when deciding whether to grant a Rule 37
    exception to prevent waste in 2001. The Commission determined that the proposed well would
    recover between 224 and 1,056 million cubic feet of gas that would otherwise be unrecoverable by
    wells at regular locations. The Long Trusts agree that the lower number of 224 million cubic feet
    of gas is based on record evidence regarding 2001 production forward, while the higher number
    was based on record evidence regarding 1998 production forward. As we have previously noted, the
    Commission has broad discretion in determining which factors to consider when granting a Rule 37
    exception and how much weight to give each factor. See 
    Halbouty, 357 S.W.2d at 374
    ; Gulf Land
    
    Co., 131 S.W.2d at 85
    . Because the record demonstrates the Commission considered that from 2001
    forward the proposed well would recover 224 million cubic feet of gas that would otherwise be
    unrecoverable, we find no merit in the Long Trusts’ argument, and we conclude that there is a
    10
    To the extent that Long Trusts complain that the Commission allowed UPRC to omit
    “selected regular locations” from its analysis, the Long Trusts point to a second well that UPRC
    could have drilled at a regular location on another adjacent tract. In considering whether to grant a
    Rule 37 exception applicable to this tract, the Commission in its discretion was entitled to accept or
    reject the testimony and evidence in whole or in part, see City of Corpus Christi v. Public Util.
    Comm’n, 
    188 S.W.3d 681
    , 695 (Tex. App.—Austin 2005, pet. denied); Railroad Comm’n v. Lone
    Star Gas Co., 
    618 S.W.2d 121
    , 125 (Tex. Civ. App.—Austin 1981, no writ), and we may not
    substitute our judgment for that of the Commission on questions committed to the Commission’s
    discretion. Texas Health Facilities Comm’n v. Charter Med.-Dallas, Inc., 
    665 S.W.2d 446
    , 452
    (Tex. 1984); H.G. Sledge, Inc. v. Prospective Inv. & Trading Co., Ltd., 
    36 S.W.3d 597
    , 602
    (Tex. App.—Austin 2000, pet. denied).
    29
    reasonable basis in the record to support the Commission’s conclusion that a Rule 37 exception was
    necessary in 2001 to prevent waste.
    We therefore reject the Long Trusts’ claim that the Commission’s order is not
    supported by substantial evidence, and we overrule the Long Trusts’ second issue.
    CONCLUSION
    Having overruled the parties’ issues on appeal, we affirm the judgment of the
    district court affirming the Commission’s final order.
