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 

Appellate Case: 14-6122 Document: 01019405523 Date Filed: 03/26/2015 Page: 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.

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. 

Appellate Case: 14-6122 Document: 01019405523 Date Filed: 03/26/2015 Page: 4 
-5- 

 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 

Appellate Case: 14-6122 Document: 01019405523 Date Filed: 03/26/2015 Page: 5 
-6- 

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. 

Appellate Case: 14-6122 Document: 01019405523 Date Filed: 03/26/2015 Page: 6 
-7- 

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 

Appellate Case: 14-6122 Document: 01019405523 Date Filed: 03/26/2015 Page: 7 
-8- 

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 

Appellate Case: 14-6122 Document: 01019405523 Date Filed: 03/26/2015 Page: 8 
-9- 

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 

Appellate Case: 14-6122 Document: 01019405523 Date Filed: 03/26/2015 Page: 9 
-10- 

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 

Appellate Case: 14-6122 Document: 01019405523 Date Filed: 03/26/2015 Page: 10 
-11- 

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.”).

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”). 

Appellate Case: 14-6122 Document: 01019405523 Date Filed: 03/26/2015 Page: 12 
-13- 

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. MidCentury 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, 

Appellate Case: 14-6122 Document: 01019405523 Date Filed: 03/26/2015 Page: 13 
-14- 

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. 

Appellate Case: 14-6122 Document: 01019405523 Date Filed: 03/26/2015 Page: 14 
-15- 

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 

Appellate Case: 14-6122 Document: 01019405523 Date Filed: 03/26/2015 Page: 15 
-16- 

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. 

Appellate Case: 14-6122 Document: 01019405523 Date Filed: 03/26/2015 Page: 16 
-17- 

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 

Appellate Case: 14-6122 Document: 01019405523 Date Filed: 03/26/2015 Page: 17 
-18- 

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 

Appellate Case: 14-6122 Document: 01019405523 Date Filed: 03/26/2015 Page: 18 
-19- 

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 

Appellate Case: 14-6122 Document: 01019405523 Date Filed: 03/26/2015 Page: 19 
-20- 

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 

Appellate Case: 14-6122 Document: 01019405523 Date Filed: 03/26/2015 Page: 20 
-21- 

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 

Appellate Case: 14-6122 Document: 01019405523 Date Filed: 03/26/2015 Page: 21 
-22- 

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). 

Appellate Case: 14-6122 Document: 01019405523 Date Filed: 03/26/2015 Page: 22 
-23- 

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. 

Appellate Case: 14-6122 Document: 01019405523 Date Filed: 03/26/2015 Page: 23 
-24- 

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. 

Appellate Case: 14-6122 Document: 01019405523 Date Filed: 03/26/2015 Page: 24 
-25- 

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. 

III. CONCLUSION 

For the foregoing reasons, we AFFIRM.
