I prepared this post before Ida. It might now be perceived as cynical, or unsympathetic to the plight of those affected in South Louisiana and the Northeast. Is the intensity of hurricanes exacerbated by global warming? Some say it is; some say it isn’t. Regardless, what to know and do about climate change
Contract Disputes

Co-author Rees LeMay*
In Apollo Exploration, LLC v. Apache Corp., Texas’ 11th Court of Appeals analyzed several provisions of purchase and sale agreements in a complex oil and gas transaction and demonstrated a measured, text-centered approach to the interpretation of contract language.
Significant parts of the holding hinged on the Court’s reference to…
A Long-Running Dispute Over an Acquisition Agreement is Returned to the Trial Court

Co-author Rusty Tucker
This is another chapter in the dispute between Eagle Oil & Gas Co. and. TRO-X, L.P. The litigation arises out of an agreement to acquire and sell oil and gas leases. Here, TRO-X alleges that Eagle failed to remit a share of revenues from production that commenced after the first suit between the parties ended.
Background
In 2005 TRO-X and Eagle entered into an acreage acquisition agreement for leases in Pecos and Reeves counties. The interests would be acquired in Eagle’s name for both parties. Each party could choose to retain a percentage of un-promoted working interests in the prospects, and the remaining interests would be sold to third parties. Profitable sales would yield either “cash proceeds” or “non-cash proceeds.” The agreement included an AMI.

Ambiguity Foils Right of Way Agreement
Co-author Brittany Blakey
The central issue in the Texas case of Cook v. Cimarex Energy Co.: Did Cook grant Cimarex a right of way across Cook’s land to the location of two Cimarex wells. No he didn’t. Reversing the trial court, the court of appeals concluded that two Contracts of Release were ambiguous. Neither…
Defective Drill Pipe+Delivery Ticket=Lawsuit
What could possibly go wrong when drill pipe and a delivery ticket are sent to a well location? Well …
The facts
In Knight Oil Tools v. Rippy Oil Company, Knight rented drill pipe to Rippy for an Eagle Ford well. A delivery ticket represented that the pipe complied with API premium class standards. The pipe, marked with two white bands, was supposed to meet standards for API premium class pipe. Some of the pipe did not comply with the standards.
(The physical condition of used drill pipe is indicated by an industry-recognized system of colored bands, with each color representing a certain physical condition.)
The pipe broke in the hole because of what the parties agreed was fatigue. Rippy abandoned the well and an offset well was unsuccessful. Rippy sued Knight to recover damages for the lost well and Knight counterclaimed for unpaid invoices.
Partial summary judgment for the customer

Texas Supreme Court Deems Continuous Development Clause Ambiguous
Co-author Skyler Stuckey
In Endeavor Energy Resources, L.P. v. Energen Resources Corp. et al. the Supreme Court of Texas construed a continuous development clause in an oil and gas lease covering 11,300 acres in Howard County. After the primary term, lessee Endeavor could retain acreage by drilling a new well every 150 days. The clause gave Endeavor “ … the right to accumulate unused days in any 150-day term during the continuous development program in order to extend the next allowed 150-day term between the completion of one well and the driling of a subsequent well.
After the primary term, Endeavor drilled 12 wells that extended the lease. Endeavor began drilling a 13th well 320 days after completing the preceding well. In the ensuing period Energen top-leased the supposedly non-retained parcels. Litigation ensued.
The dispute focused on how to calculate the number of “unused days”. Endeavor argued that it could carry forward unused days across multiple 150-day terms. Energen argued that unused days in any given 150-day term could be carried forward only once, to the next term.

Texas NPRI Burdened with Post-Production Costs

Co-author Rusty Tucker
BlueStone Nat. Res. II, LLC v. Nettye Engler Energy, LP is another Texas case deciding whether language creating a nonparticipating royalty interest prohibited deduction of post-production costs. (Spoiler alert: it didn’t. Read on to learn why.)
The Deed
By a 1986 Deed Engler’s predecessors conveyed land to BlueStone’s predecessor. Grantor reserved an undivided 1/8th NPRI in the minerals and was entitled to 1/8th of gross production, “ … to be delivered to Grantor’s credit, free of cost in the pipe line, if any, otherwise free of cost at the mouth of the well or mine … .” (emphasis ours).

Lessons from an Operating Agreement Dispute

Co-author Rusty Tucker
Jatex Oil & Gas, L.P. v. Nadel & Gussman Permian, L.L.C. presents several teachable moments:
- The Texas Property Owner Rule does not allow a non-expert to testify on matters requiring expert testimony.
- The operator may pay proceeds from a well to the lender to whom the working interest owner made a collateral assignment of net revenues from the well.
- A claim for failure to act as a reasonbly prudent operator for failing to comply with an operating agreement is a contract claim, not a tort claim.
