    ORDER AND JUDGMENT*
    Before BACHARACH, BALDOCK and McHUGH, Circuit Judges.
    This case involves a dispute over rights in certain oil and gas property located in
    Canadian County, Oklahoma. Plaintiffs David Kirk and J.D. Kirk, LLC (collectively
    Kirk) appeal the decisions of the United States District Court for the Western District of
    Oklahoma, denying Kirk’s quiet title claim against defendant Cimarex Energy Company
    (Cimarex), and Kirk’s alternative claim seeking specific performance of a preferential

    law of the case, res judicata, and collateral estoppel. It may be cited, however, for its
    persuasive value consistent with Federal Rule of Appellate Procedure 32.1 and 10th
    Circuit Rule 32.1.
    right to purchase in a Joint Operating Agreement. Exercising jurisdiction under 28 U.S.C.
    § 1291, we affirm.
    I.   BACKGROUND
    A. Factual Background
    The parties dispute the ownership of certain oil and gas leases and the contractual
    rights to operate in a 640-acre section of land in Canadian County, Oklahoma, identified
    as Section 24. Located within Section 24 are two wells significant to this appeal. The first
    is the Kitson No. 1 well, which drills into the Morrow Formation located above 11,000
    feet below ground. A second well, the Rother 1-24H well, is also located in Section 24
    and drills into the Woodford Shale Formation, which is located below 11,000 feet. The
    Oklahoma Corporation Commission has established spacing orders that govern the
    extraction and division between leaseholders of oil and gas contained in each formation
    in Section 24. Both Kirk and Cimarex claim an interest in the oil and gas extracted from
    the Woodford Shale Formation.
    Specifically, Kirk claims an interest in deep formation rights in various leases
    located in Section 24. The parties direct our attention to five leases relevant on appeal:
    Lease No. 1—Lessor Henry Rauh, et ux.; Lease No. 3—Lessor Henry H. Girard, et ux.;
    Lease No. 4—Lessor The Prospect Company; Lease No. 13—Lessor Myers Jr., M.T. et
    -2-
    al, trustees; and Lease No. 24—Lessor William H. Meyer et ux.1 But Kirk seeks to quiet
    title to deep formation interests in only three of them: Lease Nos. 4, 13, and 24
    (collectively, the Leases).2
    Kirk also asserts it is entitled to “contract rights” to operate in 53.3333 unleased
    acres located in Section 24. According to Kirk, this entitlement arises under a 1968 Joint
    Operating Agreement (the Joint Operating Agreement), which gives parties to the
    agreement a relative percentage of “[a]ll production of oil and gas from the Unit Area.”
    Under the terms of the Joint Operating Agreement, the Unit Area includes Lease Nos. 4,
    13, and 24, as well as an “[u]nleased oil and gas mineral interest contributed by Cities
    1
    The parties have identified various relevant leases by lease number and lessor.
    Because the leases in the relevant documents are not numbered, we have identified them
    by reference to the lessor.
    2
    Before the district court and on appeal, the parties seemed confused about the
    leases in which Kirk seeks to quiet title. This imprecision required us to invest significant
    time combing through the record to identify and trace the leases at issue. For example, in
    Kirk’s Third Amended Complaint, it at times seeks an interest in Leases 3, 4, and 13,
    which Kirk identified as the “Subject Leases.” But at other times in the Third Amended
    Complaint, Kirk seeks to quiet title in Lease Nos. 1, 3, 4, 13, and 24. Before the district
    court, Cimarex conceded it owned no interest in Lease No. 3, and at oral argument before
    this court, the parties agreed that Kirk seeks to quiet title in Lease Nos. 1, 4, and 13. As
    explained in detail below, however, the relevant documents show Cimarex does not have
    an interest in Lease No. 1; it holds record title to Lease Nos. 4, 13, and 24. Accordingly,
    we assume for the purposes of this appeal that Kirk seeks quiet title against Cimarex in
    the deep formation interests covered in these three leases: 4, 13, and 24.
    -3-
    Service Oil Company: An undivided 1/3 interest in the minerals underlying the NE/4 of
    Section 24-13N-10W.”3
    The Joint Operating Agreement also contains a preferential right to purchase
    provision, which requires any party to give written notice to the other parties to the Joint
    Operating Agreement of the proposed sale of any interest in the Unit Area, the
    prospective purchaser, the purchase price, and all other terms of the offer. The other
    parties then have fifteen days after receipt of the notice to purchase the interest at the
    same terms and conditions. Kirk became a party to the Joint Operating Agreement in
    1991. At this time, the other parties to the Joint Operating Agreement were OXY USA,
    Inc., William Schofield, Conoco Inc., Amoco Production Company (Amoco), and John
    W. Coffey Est. Trust.
    1. The Dispute Over the Deep Formation Interests in Lease Nos. 4, 13, and 24
    and the Contract Rights to Operate in the 53.3333 Unleased Acres
    The genesis of the parties’ present dispute concerning ownership of the deep
    formation rights in the Leases and the contract rights in 53.3333 unleased acres is a 1996
    agreement under which the original owner of these interests, Amoco, transferred to Kirk
    “all right, title and interest in and to” the Leases and contract rights. Kirk did not record
    the assignment until approximately five years later, in 2001.
    3
    It is undisputed that the provision referencing the “1/3 undivided interests”
    describes the same 53.3333 unleased acres in which Kirk claims contractual operating
    rights.
    -4-
    In 1997, prior to Kirk’s 2001 recordation, Amoco sold a large number of oil and
    gas leases to Gothic Energy Co. (Gothic), including its interest in the same Leases and
    contract rights previously transferred to Kirk. Specifically, Amoco and Gothic entered
    into a Purchase and Sale Agreement (the PSA), under which Amoco sold to Gothic
    certain “Properties” located in Section 24. The PSA defines “Properties” as including
    [a]ll of [Amoco’s] right, title and interests in, to and under, or derived from,
    the oil and gas leasehold interests, royalty interests, overriding royalty
    interests, mineral interests, production payments, net profits interests and
    surface interests . . . described in Exhibit “A.”
    The PSA’s Exhibit A does not identify any particular leases, but instead contains a list of
    “Working Interests, Net Revenue Interests and Defect Value.” It divides these interests
    into “Producing Properties” and “Nonproducing Properties.” Listed as a “Producing
    Property” in Exhibit A of the PSA is a property identified as the “Kitson Unit.” In
    addition, the PSA transferred to Gothic “[a]ll of [Amoco’s] right, title and interests in, to
    and under, or derived from, all of the presently existing and valid . . . operating
    agreements . . . and other contracts . . . (including but not limited to the material contracts
    described in Exhibit ‘C’).” Exhibit C expressly lists as a “material contract” the Joint
    Operating Agreement. The PSA also contains an integration clause.
    One year later, Amoco and Gothic entered into an Assignment and Bill of Sale
    (the Assignment), which they made retroactively effective as of 1997. Through this
    Assignment, Amoco conveyed to Gothic
    [a]ll of [Amoco’s] right, title, and interests in, to and under, or derived
    from, the oil and gas leasehold interests, royalty interests, overriding
    -5-
    royalty interests, mineral interests, production payments, net profits
    interests and surface interests . . . described in Exhibit “A.”
    The Assignment’s Exhibit A expressly lists the Leases. The Assignment also incorporates
    by reference the terms of the PSA and provides that in the event of a conflict between the
    documents, the terms of the PSA control. Gothic recorded the Assignment in 1998, three
    years before Kirk recorded the assignment to him from Amoco.
    After Gothic executed the Assignment, Chesapeake Exploration, LLC
    (Chesapeake) acquired Gothic by merger and thereby obtained all of the rights and
    interests in the Leases and Joint Operating Agreement that Amoco had assigned to Gothic
    in the PSA and Assignment. In 2008, Chesapeake entered into a Purchase and Sale
    Agreement with Cimarex and assigned it “[a]ll of [Chesapeake’s] right, title, and interest
    in and to” the Leases “insofar and only insofar as to” Chesapeake’s deep formation
    rights. Chesapeake also conveyed to Cimarex its contractual operating rights under the
    Joint Operating Agreement to develop the 53.3333 unleased acres. Cimarex recorded its
    assigned interests in October 2008.4
    2. The Drilling and Completion of the Rother 1-24H Well
    Beginning in February 2008, Devon Energy Company (Devon) began soliciting
    interested lessors of Section 24 to participate in the drilling and completion of the Rother
    1-24H well. Devon, which was not an original party to the Joint Operating Agreement,
    4
    In 2012, Cimarex recorded a corrected assignment, which clarified that in the
    2008 conveyance, Chesapeake intended to transfer to Cimarex the Leases as well as the
    contractual operating rights to develop the 53.3333 unleased acres in Section 24.
    -6-
    contacted Kirk to advise that it proposed to drill a 16,000-foot well into the Woodford
    Shale in Section 24. Devon predicted the “dry hole cost” would be $4,997,500.00 and the
    total cost to drill and complete the well would be $7,035,800.00. Devon invited Kirk to
    select one of three options: Kirk could participate by paying a proportionate share of
    costs; lease its interest for $600 per acre for a three-year term, reserving a 3/16 royalty
    interest; or lease its interest for $200 per acre, reserving a 1/4 royalty interest. Later that
    same month, Kirk received notice that Devon had filed a pooling application for the
    Woodford Shale Formation and other adjacent formations in Section 24 with the
    Commission and that the Commission had scheduled a hearing on the application.
    In March of 2008, Kirk also received a copy of a Commission order granting
    Devon’s pooling application and designating Devon as the well operator. The order
    advised Kirk that it could elect one of the three options Devon had initially proposed.
    Attached to the order was a list of all interest owners in Section 24, which listed both
    Chesapeake and Chesapeake/Gothic. Kirk advised Devon it would not participate in the
    drilling and completion of the Rother 1-24H well, but would instead lease its interest for
    $200 and receive a 1/4 royalty interest.
    In October 2008, Cimarex acquired some of Chesapeake’s rights in Section 24 and
    elected to participate in the drilling and completion of the Rother 1-24H well.
    Construction on the well began in March 2009 and was completed in June of the same
    year. As predicted, the well was drilled into the Woodford Shale Formation, with
    perforations from 12,968 to 17,222 feet below the surface, costing over $7.4 million to
    -7-
    complete. Of that sum, Cimarex paid approximately $1.4 million. Since its completion,
    the well has produced approximately 4,269,674 cubic feet of natural gas and
    approximately 54,237 barrels of condensate.
    In November 2009, Devon sent Kirk a letter advising him that a title attorney had
    discovered Kirk and Cimarex had recorded competing interests in Section 24. Devon
    advised Kirk that “[u]ntil record title can be clarified, your interest will remain in
    suspen[ded] status. Please review this requirement and forward the needed
    documentation at your earliest convenience.” Also enclosed with the letter was a
    proposed division order from the Commission, which listed Cimarex as a working
    interest owner in Section 24.
    In an effort to remove any questions about title to the Leases and contract rights, in
    October 2010, an attorney for Cimarex sent Kirk a letter that proposed a Stipulation and
    Cross-Conveyance. By the Stipulation and Cross-Conveyance’s terms, Kirk would retain
    a 100% interest in Lease Nos. 1 and 3, and a 40.45% interest in the Leases (Lease Nos. 4,
    13, and 24). In turn, Chesapeake would retain a 59.55% interest in the Leases, as well as
    a 100% interest in the contractual operating rights to the 53.333 unleased acres. Rather
    than sign the Stipulation and Cross-Conveyance, Kirk filed this lawsuit.
    B. Procedural Background
    In 2011, Kirk filed a Petition in Oklahoma state court alleging Cimarex breached
    the Joint Operating Agreement’s preferential purchase provision (Count I) and tortiously
    interfered with Kirk’s preferential purchase rights (Count IV). It sought an accounting
    -8-
    and specific performance of the Joint Operating Agreement (Counts II and III,
    respectively). Cimarex removed the case to the United States District Court for the
    Western District of Oklahoma under 28 U.S.C. § 1332 and successfully moved to dismiss
    Counts I and IV of the Petition. The district court held that Cimarex—as merely the buyer
    from Chesapeake—was not a party that could have breached the preferential right to
    purchase provision contained in the Joint Operating Agreement and that Kirk’s tort claim
    was time barred.
    Kirk then filed a First Amended Complaint in the district court, alleging that
    Cimarex was trespassing in bad faith through participating in the Rother 1-24H well’s
    deep formation drilling activities. Kirk alleged that the Amoco-Gothic conveyance failed
    to transfer any interest in Section 24 to Gothic and therefore Cimarex could not have
    obtained these interests from Chesapeake. Kirk also realleged that it was entitled to
    specific performance of the Joint Operating Agreement’s preferential right to purchase.
    The district court dismissed the trespass claim but allowed Kirk’s claim for specific
    performance to proceed in equity.
    Kirk then filed a Second Amended Complaint, seeking quiet title and reasserting
    that Cimarex had trespassed on its deep formation interests. According to Kirk, it owned
    the deep formation rights in the Leases through the assignment from Amoco in 1996. In
    support, Kirk alleged that the Amoco-Gothic conveyance transferred only a shallow
    drilling interest in the Leases and therefore Gothic could not have transferred any deep
    formation rights to Chesapeake. Kirk further claimed that Chesapeake’s attempt to assign
    -9-
    deep formation interests in the Leases to Cimarex was invalid because Chesapeake did
    not own any such interests to assign.
    Cimarex moved to dismiss, and Kirk sought partial summary judgment. The
    district court converted Cimarex’s motion to one seeking summary judgment, which,
    after supplemental briefing, the court granted. It determined that the PSA and Assignment
    between Amoco and Gothic unambiguously transferred all of Amoco’s interest in the
    Leases, including deep formation rights, to Gothic. In so holding, the court declined to
    consider extrinsic evidence in the form of the Commission’s spacing order regarding the
    Kitson No.1 well and a previous agreement between Amoco and Essex Exploration, Inc.
    (Essex) related to certain shallow formation interests in Section 24. The court granted
    summary judgment in favor of Cimarex on Kirk’s quiet title claim but allowed Kirk’s
    equitable claim for specific performance of the preferential right to purchase to proceed.
    Thereafter, Kirk filed a Third Amended Complaint against Cimarex, reasserting its
    claim for quiet title and trespass. But this time it proceeded under a different legal theory.
    It alleged that even if in 1997 Amoco did convey deep formation interests to Gothic,
    Gothic’s 2008 conveyance to Cimarex did not include such rights because Kirk recorded
    its interest first, in 2001. Kirk also asserted that the Amoco-Gothic conveyance did not
    convey any contractual rights in the 53.3333 unleased acres to Gothic.
    Cimarex again moved to dismiss Kirk’s quiet title claim. Cimarex first noted the
    absence of any evidence that Gothic had knowledge of Kirk’s unrecorded interest in the
    deep formation rights. It then argued that as a bona fide purchaser for value (BFP) that
    -10-
    recorded its interest first, Gothic took the deep formation interests free of Kirk’s
    competing interest. And that under the shelter rule,5 Cimarex enjoyed the same BFP
    status as Gothic, irrespective of whether it had constructive notice of Kirk’s 2001
    recordation. Cimarex also claimed the Amoco-Gothic conveyance plainly and
    unambiguously transferred to Gothic the contractual rights to operate in the 53.3333
    unleased acres. The district court agreed with Cimarex and dismissed Kirk’s quiet title
    claim in the Third Amended Complaint.
    Finally, Cimarex moved for summary judgment on Kirk’s equitable claim for
    specific performance of the Joint Operating Agreement’s preferential right to purchase.
    The court granted Cimarex’s motion under the doctrine of laches, holding that Kirk had
    waited too long to bring its claims, while Devon and Cimarex incurred the costs of
    developing the Rother 1-24H well. Having disposed of each claim in the Third Amended
    Complaint, the district court entered judgment in favor of Cimarex. Kirk appeals.
    5
    The shelter rule provides that one who is not a BFP, but who takes interest in the
    property from a BFP, may take shelter in the latter’s protected status. See, e.g., Knowles
    v. Freeman, 
    649 P.2d 532
    , 535 (Okla. 1982) (“Title to the mineral interest having passed
    to a bona fide purchaser prior to the recording of the ‘corrective’ deed, it becomes of no
    consequence whether defendant had notice of the claim of plaintiffs that the conveyance
    included the mineral interest in the 40-acre tract at the time defendant acquired title.”);
    Gay v. Williams, 
    226 P. 88
    , 91 (Okla. 1924) (“the plaintiffs . . . , having taken title to the
    mortgage from [a] bona fide purchaser, are entitled to the protection afforded a bona fide
    purchaser, whether such plaintiffs in error made inquiry in regard to the title or used
    diligence in examining the same or not.”).
    -11-
    II.   DISCUSSION
    On appeal, Kirk claims the district court erred in two respects: by dismissing its
    quiet title claim and by holding that its specific performance claim is barred by laches.
    We consider, and reject, both claims.
    A. Kirk does not hold title to deep formation interests in the Leases or the contractual
    rights in the 53.3333 unleased acres.
    Kirk first claims the district court erred in rejecting its quiet title claim. Kirk
    argues, as it did in the district court, that Amoco assigned the deep formation interests in
    the Leases and the contractual rights in the 53.3333 acres to Kirk in 1996 and did not
    subsequently assign these same interests to Gothic. According to Kirk, the district court
    erred in interpreting the Amoco-Gothic PSA and Assignment, which, when properly read,
    limit the conveyance to shallow interests in the Leases and do not convey any contractual
    rights to operate in the 53.3333 acres.6 We review the district court’s interpretation of the
    PSA and Assignment de novo. Doe v. City of Albuquerque, 
    667 F.3d 1111
    , 1122 (10th
    Cir. 2012).
    6
    As previously explained, the district court dismissed Kirk’s quiet title claim in its
    Third Amended Complaint through application of the shelter rule, concluding that
    because Gothic was a BFP of the deep formation interests, Cimarex could take shelter in
    Gothic’s status and take those interests free of any competing claim. On appeal, Kirk
    does not challenge the district court’s application of the shelter rule, asserting instead that
    Gothic could not have been a BFP of the deep formation interests in the Leases because
    Amoco never transferred those interests to Gothic. We limit our inquiry on appeal
    accordingly. See Constitution Party of Kan. v. Kobach, 
    695 F.3d 1140
    , 1144 (10th Cir.
    2012) (where “a party chooses not to assert . . . a certain argument on appeal, we
    generally will not consider that argument in our review”).
    -12-
    The PSA provides that it “shall be governed by and construed under the Laws of
    the State of Oklahoma.” In interpreting the terms of the PSA and Assignment, therefore,
    we are bound by the Oklahoma Supreme Court’s most recent statement of applicable law,
    and we follow any state intermediate court decisions absent “convincing evidence that the
    highest court would decide otherwise.” Commonwealth Prop. Advocates, LLC v. Mortg.
    Elec. Registration Sys., Inc., 
    680 F.3d 1194
    , 1204 (10th Cir. 2011) (internal quotation
    marks omitted).
    In Oklahoma, “[t]he primary goal of contract interpretation is to determine and
    give effect to the intention of the parties at the time the contract was made.” May v. Mid-
    Century Ins. Co., 
    151 P.3d 132
    , 140 (Okla. 2006). In arriving at the parties’ intent, we
    give the terms of an instrument their plain and ordinary meaning. 
    Id. And we
    consider a
    contract “as a whole so as to give effect to all its provisions without narrowly
    concentrating upon some clause or language taken out of context.” Mercury Inv. Co. v.
    F.W. Woolworth Co., 
    706 P.2d 523
    , 529 (Okla. 1985). This requires us to reconcile and
    harmonize apparently conflicting provisions so as to give meaning to both, rather than
    rendering a provision meaningless. 17A C.J.S. Contracts § 412. Likewise, we must read
    together “[s]everal contracts relating to the same matters, between the same parties, and
    made as parts of substantially one transaction,” Okla. Stat. tit. 15, § 158, and consider as
    part of the contract all terms expressly incorporated by reference, see Monkey Island Dev.
    Auth. v. Staten, 
    76 P.3d 84
    , 88 (Okla. Civ. App. 2003). If, after engaging in this inquiry,
    -13-
    the language of a contract is clear and unambiguous on its face, we must give effect to its
    terms as expressed within its four corners. Mercury Inv. 
    Co., 706 P.2d at 529
    .
    Guided by these principles of contract interpretation, we agree with the district
    court that Amoco unambiguously transferred its contractual rights in the 53.3333
    unleased acres as well as its deep formation rights in the Leases to Gothic. As an initial
    matter, we can easily dispose of Kirk’s claim that it is entitled to contractual operating
    rights in the 53.3333 unleased acres located in Section 24 because Amoco conveyed these
    rights to Gothic in the PSA. By its plain terms, the PSA conveys to Gothic “[a]ll of
    [Amoco’s] . . . right, title and interests in, to and under, or derived from, all of the
    presently existing and valid . . . operating agreements,” and specifically identifies the
    Joint Operating Agreement. Therefore, when Chesapeake acquired Gothic, it obtained
    Gothic’s contract rights in the 53.3333 unleased acres and was free to assign them to
    Cimarex.
    Likewise, we are confident the Amoco-Gothic conveyance unambiguously
    transferred Amoco’s deep formation rights in the Leases to Gothic. By its plain terms, the
    Assignment to Gothic conveys
    [a]ll of [Amoco’s] right, title and interests in, to and under, or derived from,
    the oil and gas leasehold interests, royalty interests, overriding royalty
    interests, mineral interests, production payments, net profits interests and
    surface interests which are described in Exhibit “A.”
    In turn, the Assignment’s Exhibit A describes each of the Leases. There is nothing in the
    Assignment or on its Exhibit A that limits the conveyance to a particular depth.
    -14-
    Nevertheless, Kirk argues the Assignment’s seemingly broad grant of “all of
    [Amoco’s] right title and interest in” the Leases is modified or limited by the reference of
    Exhibit A of the PSA to a “Producing Property” identified as the “Kitson Unit.”
    According to Kirk, this reference implies either that Amoco intended to convey only
    shallow interests in the Leases because the Kitson No. 1 well is spaced to drill only into
    the Morrow Formation or that the documents are ambiguous in this respect. We disagree.
    Even if the PSA could be reasonably interpreted to convey a limited assignment of
    specific net revenue and working interests in a producing property identified as the
    “Kitson Unit,” this does not mean that Amoco intended to include any particular depth
    limitation when it broadly assigned the Leases to Gothic in the subsequent Assignment.
    Nor can the documents, when read together, be reasonably interpreted to do so. The
    portion of the PSA’s Exhibit A relied on by Kirk is limited to “Working Interests, Net
    Revenue Interests and Defect Value” in various “Producing” and “Nonproducing”
    properties. It does not reference the Leases or purport to list the underlying leases that
    give rise to these working interests, net revenue interests, or defect values, which Amoco
    then unambiguously transferred to Gothic by the Assignment.
    Moreover, there is nothing that would render the Agreement’s more limited
    conveyance of interest in the producing property identified as the Kitson Unit
    inconsistent with the Assignment’s broader transfer of “all of [Amoco’s] right title and
    interest to” the Leases. The PSA nowhere indicates Amoco intended to limit the
    conveyance to only working interests, net revenue interests, and defect value in the
    -15-
    producing properties identified in the PSA. Nor does the Assignment purport to reflect
    any such limitation. To the contrary, careful examination of the Assignment belies such
    an assertion.
    Where Amoco intended to convey a less than complete interest in a particular
    lease, it specifically noted the limitation on Exhibit A to the Assignment. For example,
    with respect to one lease identified by reference to Lessor Shelby et al Vilette L., the
    exhibit notes that the lease transferred is “less and except the wellbore of the Meiwes A-2
    well located 950 feet east of the center of the SW/4 of said Section 27, but only as to the
    Morrow Formation, and less and except the Morrow Formation.” Exhibit A to the
    Assignment contains no similar depth limitation for any of the Leases at issue in the
    instant case.
    Reading the Assignment and PSA together, we affirm the district court’s
    conclusion that they unambiguously transferred to Gothic Amoco’s working interests, net
    revenue interests, and defect value in the producing property identified as the Kitson
    Unit, as well as all of its “right, title and interest” in the Leases, which necessarily
    includes deep formation rights. As required by Oklahoma law, this interpretation
    considers all parts of the contract and avoids creating unnecessary conflict between the
    more limited conveyance described in the PSA and the broader conveyance described in
    the Assignment.
    -16-
    Because the district court was correct that Amoco unambiguously assigned to
    Gothic its deep formation rights in the Leases, it also was correct in refusing to consider
    extrinsic evidence in interpreting the PSA and Assignment.
    In sum, we conclude Gothic acquired Amoco’s contractual operating interests in
    the 53.3333 unleased acres and its deep formation rights in the Leases under the
    unambiguous terms of the Agreement and Assignment. Chesapeake subsequently
    acquired these interests through merger and then transferred them intact to Cimarex. The
    district court therefore correctly rejected Kirk’s quiet title claim.
    B. Cimarex is entitled to summary judgment on Kirk’s equitable claim for specific
    performance.
    Second, Kirk challenges the district court’s application of the doctrine of laches to
    bar Kirk’s claim for specific performance of the Joint Operating Agreement’s preferential
    right to purchase provision. Cimarex asks us to affirm the district court’s decision on the
    basis of laches and alternatively asks us to affirm on five additional grounds raised
    before, but not ruled on by, the district court. We begin by discussing the district court’s
    laches ruling. Because we conclude the district court correctly determined Cimarex is
    entitled to summary judgment on the basis of laches, we do not address the alternate
    grounds advanced by Cimarex.
    Generally, we review a district court’s laches decision for an abuse of discretion.
    See Biodiversity Conservation Alliance v. Jiron, 
    762 F.3d 1036
    , 1090 (10th Cir. 2014);
    Jicarilla Apache Tribe v. Andrus, 
    687 F.2d 1324
    , 1337 (10th Cir. 1982) (“As with other
    -17-
    equitable defenses, the existence of laches is a question primarily addressed to the
    discretion of the trial court.” (internal quotation marks omitted)). But where, as here, the
    district court grants a defendant summary judgment on the basis of laches, our review is
    de novo. See Jacobsen v. Deseret Book Co., 
    287 F.3d 936
    , 948 (10th Cir. 2002). In
    determining whether Cimarex is entitled to summary judgment, we view all facts and
    reasonable inferences therefrom in the light most favorable to the nonmoving party, Kirk.
    See Hutchinson v. Pfeil, 
    105 F.3d 562
    , 564 (10th Cir. 1997). Like Kirk’s quiet title claim,
    the parties agree Oklahoma law governs our laches inquiry. As the party invoking laches,
    Cimarex bears the burden of establishing (1) Kirk unreasonably delayed in bringing an
    action against Cimarex for specific performance of the preferential right to purchase
    provision and (2) Cimarex was materially prejudiced by that delay. See Hedges v.
    Hedges, 
    66 P.3d 364
    , 369 (Okla. 2002). Before we undertake the analysis of whether the
    district court correctly concluded Cimarex met that burden, we pause to dispel Kirk’s
    notion that Cimarex must also prove it has suffered irreparable harm.
    Although Kirk is correct that the Oklahoma Supreme Court has stated, “The party
    invoking the defense of laches must prove that it suffered some irreparable damage or
    loss because of a change of conditions in relying on the inaction and indifference of the
    other party,” Clark v. Unknown Heirs of Osborn, 
    782 P.2d 1384
    , 1386 (Okla. 1989), we
    do not read Clark as establishing irreparable harm as a required element. Rather, Clark
    indicates a party may establish prejudice through showing “irreparable damage or loss.”
    See 
    id. (emphasis added).
    Interpreting Clark in this way is consistent with the weight of
    -18-
    authority from the Oklahoma courts, this circuit, and other states, none of which have
    required a plaintiff to establish irreparable harm. See, e.g., Nichols v. Nichols, 
    222 P.3d 1049
    , 1056 n.24 (Okla. 2009) (“Before a claim will be considered barred by laches it
    must be shown that (a) there has been an unreasonable delay in the commencement of
    proceedings to enforce the claim and that (b) by reason of this delay the defendant has
    been materially prejudiced”); Smith v. Baptist Found. of Okla., 
    50 P.3d 1132
    , 1138 (Okla.
    2002) (citing Clark for the position that “[t]he party invoking the laches defense must
    show unreasonable delay coupled with knowledge of the relevant facts resulting in
    prejudice”); 
    Hedges, 66 P.3d at 369
    (“Before a claim will be considered barred by laches
    it must be shown that (a) there has been an unreasonable delay in the commencement of
    proceedings to enforce the claim and that (b) by reason of this delay the defendant has
    been materially prejudiced.”); Chesapeake Operating, Inc. v. Carl E. Gungoll
    Exploration, Inc., 
    116 P.3d 213
    , 216 (Okla. Civ. App. 2005) (holding that defendant had
    established prejudice where it was induced to invest great sums of money due to the
    plaintiff’s inaction); 
    Jiron, 762 F.3d at 1091
    (stating that “[l]aches bars a claim when
    there is: (1) lack of diligence by the party against whom the defense is asserted, and (2)
    prejudice to the party asserting the defense” and noting that prejudice may be established
    where defendant has expended time and effort (internal quotation marks omitted));
    Veysey v. Veysey, 
    339 P.3d 131
    , 135 (Utah App. 2014) (“To successfully assert a laches
    defense, a defendant must establish both that the plaintiff unreasonably delayed in
    bringing an action and that the defendant was prejudiced by that delay.”). And in any
    -19-
    event, when exercising our diversity jurisdiction, we are required to follow the Oklahoma
    Supreme Court’s most recent statement of applicable law, which has plainly required
    prejudice rather than irreparable harm. See Commonwealth Prop. Advocates, LLC v.
    Mortg. Elec. Registration Sys., Inc., 
    680 F.3d 1194
    , 1204 (10th Cir. 2011); 
    Nichols, 222 P.3d at 1056
    n.24 (requiring prejudice rather than irreparable harm as an element of
    laches). Accordingly, we decline Kirk’s invitation to adopt irreparable harm as a required
    element of laches in Oklahoma.
    We now consider whether the district court correctly concluded that Cimarex is
    entitled to a laches defense as a matter of law. “Laches is an equitable defense to stale
    claims.” 
    Smith, 50 P.3d at 1138
    . “There is no arbitrary rule for when a claim becomes
    stale or what delay is excusable.” 
    Id. Rather, “[t]he
    doctrine . . . is a purely equitable one,
    and arises only whenever, from the lapse of time and laches of the plaintiff, it would be
    inequitable to allow a party to enforce his legal rights.” Phelan v. Roberts, 
    77 P.2d 9
    , 12
    (Okla. 1938). In Oklahoma, the doctrine of laches “will be rigorously applied in suits
    involving property of speculative value, such as mining and particularly oil properties.”
    Holshouser v. Lee, 
    369 P.2d 616
    , 621 (Okla. 1961). As the Oklahoma Court of Civil
    Appeals explained,
    the duty to act with dispatch is especially imperative where one claims an
    interest in property that is highly speculative. One may not withhold his
    claim to a highly speculative venture, such as was involved in these wildcat
    oil and gas leases and permits, to await the outcome of an effort to develop
    them put forth by another, and then when his efforts are crowned with
    apparent success, come in and claim the fruits thereof. . . . [L]aches does
    -20-
    not concern itself with the mere lapse of time, but with the inequity of
    permitting a claim to be enforced.
    Chesapeake 
    Operating, 116 P.3d at 216
    (quoting Winn v. Shugart, 
    112 F.2d 617
    , 622
    (10th Cir. 1940) (internal quotation marks omitted)); accord Parker v. Ryan, 
    287 P. 1006
    ,
    1008 (Okla. 1930) (explaining that a plaintiff cannot “wait several months, and, after a
    well had been discovered that greatly enhanced the value of the land, then be permitted to
    have his contract specifically enforced”); see also Socony Mobil Oil Co. v. Cont’l Oil
    Co., 
    335 F.2d 438
    (10th Cir. 1964) (applying Oklahoma law) (where parties are engaged
    in enterprises such as oil and gas leases, which fluctuate rapidly and substantially in
    value, a plaintiff cannot demand specific performance unless it asserts its rights diligently
    and without unreasonable delay); Marken v. Goodall, 
    478 F.2d 1052
    , 1054–55 (10th Cir.
    1973) (applying Wyoming law and holding laches prevented plaintiff from obtaining
    specific performance of a preferential right to purchase various oil and gas leases where,
    after the plaintiff learned of the proposed sale, he “remained silent with regard to his right
    of refusal while defendants entered upon the costly and risky . . . [venture] which
    ultimately resulted in greatly enhancing the value of the lease,” and it was “only after the
    [venture] proved successful that plaintiff broke his [two-year] silence and demanded he
    be permitted to exercise his right of refusal”).
    Guided by this authority, we agree with the district court that laches bars Kirk’s
    claim for specific performance of the Joint Operating Agreement under Oklahoma law.
    Here, it is undisputed Kirk was aware in 1991 of the Joint Operating Agreement’s
    -21-
    preferential right to purchase provision and knew the identity of the parties bound by the
    agreement at that time. As early as 2008, Kirk learned Devon, who was not a party to the
    Joint Operating Agreement in 1991, was planning to develop the Rother 1-24H well in
    the Woodford Shale Formation and was actively soliciting parties to invest in the
    operation. And importantly, in March 2008, Kirk received notice that Chesapeake—who
    was also not a party to the Joint Operating Agreement in 1991—had elected to participate
    in the drilling of the Rother 1-24H well. Yet Kirk made no effort to investigate how
    Chesapeake or Devon obtained their interest or inquire as to any other entities involved.
    Kirk likewise did not complain about the absence of written notice required by the Joint
    Operating Agreement or about any lost opportunity to exercise its preferential right to
    purchase these leaseholds. And Kirk had actual notice in November 2009 that
    Chesapeake had transferred its interests in Section 24 to Cimarex and that Cimarex was a
    working interest owner in the Rother 1-24H well. But still, Kirk waited for an additional
    sixteen months, until the well proved profitable, to seek specific performance and thereby
    reap the rewards of others’ risk, investment, and efforts. Kirk’s apparent disinterest in
    enforcing its rights under the Joint Operating Agreement for approximately three years
    precludes him from now seeking specific performance of the preferential right to
    purchase provision. See 
    Smith, 50 P.3d at 1141
    (holding that a claim was barred by laches
    where, through silence, the plaintiff acquiesced in the conduct he later sought to
    challenge).
    -22-
    Kirk asks us to reach a contrary conclusion, asserting that Cimarex failed to show
    it suffered prejudice because it has not established it invested any money into the Rother
    1-24H well or otherwise changed its position after Kirk obtained actual notice of
    Chesapeake’s breach. We are not persuaded. Although Cimarex invested the $1.4 million
    before Kirk admits it had actual notice of Cimarex’s participation in the Rother 1-24H
    well,7 this fact does not prevent Cimarex from prevailing on a laches defense. As the
    district court recognized, actual knowledge of the facts necessary to pursue a right or
    bring a cause of action is not required; constructive knowledge or the means of
    knowledge of such facts is sufficient. See, e.g., 
    id. at 1140
    (holding that a cause of action
    against defendant accrued when plaintiff had “sufficient information” to realize he had a
    claim); 
    Phelan, 77 P.2d at 11
    (“[A]s the rule is sometimes expressed, it is an essential
    element of laches that the party charged with it should have had knowledge or the means
    of knowledge of the facts creating his right or cause of action.”); Chesapeake 
    Operating, 116 P.3d at 217
    (a plaintiff may be “charged with knowledge of facts which it ought to
    have known” (internal quotation marks omitted)). Indeed, “knowledge which is sufficient
    to lead a prudent person to inquire about the matter, when it could have been ascertained
    conveniently, constitutes notice of whatever the inquiry would have disclosed, and will
    be regarded as knowledge of the facts.” Chesapeake 
    Operating, 116 P.3d at 217
    (internal
    7
    Although Cimarex does not provide the precise dates on which it invested any
    money in the drilling and completion of the Rother 1-24H well, it is reasonable to infer
    that the investment occurred sometime between October 2008, when Cimarex obtained
    Chesapeake’s interest, and June 2009, when the well was completed.
    -23-
    quotation marks omitted); see also Carter Oil Co. v. Crude Oil Co., 
    201 F.2d 547
    , 551
    (10th Cir. 1953) (“Oklahoma has held that under certain conditions one claiming an
    interest under instruments of record has a duty to improve with diligence the opportunity
    of learning that which the record discloses and that failing to do so constitutes laches.”);
    
    Winn, 112 F.2d at 622
    (“Mere ignorance of the facts will not excuse delay. One must be
    diligent and make such inquiry and investigation as the circumstances reasonably suggest
    and means of knowledge are equivalent to actual knowledge.”).
    Here, Kirk can be reasonably charged with knowledge of Chesapeake’s alleged
    breach of the Joint Operating Agreement prior to Cimarex’s investment of $1.4 million.
    In March 2008, Kirk had notice that Chesapeake, Cimarex’s predecessor in interest,
    along with other entities who were not parties to the Joint Operating Agreement in 1991,
    was engaged in the construction of the Rother 1-24H well, and was investing significant
    sums to drill and complete the well. Indeed, Devon informed Kirk that the estimated cost
    of completion would be over $7 million. Had Kirk been sincerely concerned about past or
    future breaches of the Joint Operating Agreement, rather than simply waiting to see how
    the current working interest owners fared on their investment, Kirk could easily have
    inquired into how they obtained their interests and investigated changes in record title to
    the leases. Kirk’s duty to inquire or take other reasonable efforts to diligently protect its
    rights was “especially imperative” because the interest Kirk claims—the right to purchase
    oil and gas leases—involves highly speculative and rapidly changing property. See
    Chesapeake 
    Operating, 116 P.3d at 216
    .
    -24-
    Through simple inquiry, Kirk could have discovered that Chesapeake obtained an
    interest in the Leases and contractual rights to operate in the 53.3333 acres Gothic
    obtained from Amoco in 1997. And the subsequent Chesapeake-Cimarex conveyance
    was recorded in October 2008. There is no allegation that either Chesapeake or Cimarex
    concealed anything with respect to the transfer or otherwise. See 
    Winn, 112 F.2d at 622
    .
    Once Kirk was on notice that participants in the Joint Operating Agreement were in flux
    and that substantial amounts were being invested to develop the well, it could not sleep
    on its rights. It was required to make reasonable inquiry, which would have revealed the
    Chesapeake-Cimarex transaction Kirk now claims constitutes a breach of the Joint
    Operating Agreement.
    Therefore, prior to Cimarex’s $1.4 million investment, Kirk was in the position to
    have had, through reasonable inquiry, knowledge of the facts required to enforce its
    rights under the Joint Operating Agreement—against Devon, Chesapeake, or Cimarex.
    Kirk’s failure to bring suit until years later, after the Rother I-24H well proved to be
    profitable, caused Cimarex material prejudice. The district court correctly determined that
    under Oklahoma law, Cimarex was entitled to summary judgment on the basis of laches.

    For the foregoing reasons, we AFFIRM.
