Here is a hypothetical: OilCo A and OilCo B each acquire oil and gas leases from mineral owners holding undivided interests in Blackacre. The two companies are unable to agree on a joint operating agreement. OilCo A drills and completes wells, and OilCo B becomes a non-consenting cotenant, entitled to its share of net profit from the wells after payout. Issue: When does OilCo B owe royalties to its royalty owners?
Those are the facts in Pioneer Natural Resources USA, Inc., v. Elberta M. Royalty, LLC (Tex.App.-El Paso, August 19, 2026). Pioneer and Henry Petroleum each held oil and gas leases covering the same land in Upton County. Pioneer’s lease was from Elberta M. Royalty. Henry drilled wells without a joint operating agreement from Pioneer. Pioneer did not respond to Elberta’s demands for payment of royalty, and Elberta filed suit. While the suit was pending the wells paid out, Henry paid Pioneer its share of revenue, and Pioneer then paid Elberta its share of royalty from the date of first production – two years after production began. (Pioneer and Henry subsequently did enter into a joint operating agreement.) Elberta claimed it was also entitled to statutory interest and attorneys’ fees under Texas Natural Resources Code Chapter 91.
The Court of Appeals held that Pioneer’s obligation to pay royalty under Elberta’s lease accrued when production occurred, not when Pioneer got paid, including statutory interest.
