Western District of Texas Limits Gross Proceeds Royalty Obligation to Third-Party Sale Point in Delaware Basin Dispute

YMC Royalty v. WPX Energy Permian, LLC U.S. District Court, Western District of Texas 1:24-cv-00266 active
By Joel Reese · October 12, 2026 U.S. District Court, Western District of Texas

YMC Royalty sought $1,023,258 in damages and lease termination against WPX Energy Permian over a 2016 Loving County lease, alleging underpayment through improper post-production deductions on NGLs, flared gas, and plant fuel. The Western District of Texas granted partial summary judgment for WPX, holding the lease's royalty language entitled YMC only to gross proceeds at the point of sale to third-party purchasers, limiting the cost-free obligation to that delivery point rather than downstream.

Royalty Interest Post-Production Costs Gross Proceeds Permian Basin NGL Deductions

Background

YMC Royalty brought suit against WPX Energy Permian, LLC over a 2016 oil and gas lease covering acreage in Loving County, Texas. YMC alleged WPX systematically underpaid royalties by taking improper post-production deductions across three categories: natural gas liquids extracted and sold downstream, gas flared during production operations, and volumes consumed as plant fuel during processing. YMC sought $1,023,258 in damages and, more significantly, termination of the lease itself.

The Royalty Calculation Dispute

The case turned on interpretation of the lease's royalty clause and the permissible scope of post-production cost deductions. YMC argued the lease's gross proceeds language entitled it to royalties calculated on the full value received by WPX from downstream sales, free of any deductions for transportation, processing, or other post-production costs. WPX countered that the lease unambiguously limited the lessor's cost-free entitlement to the point of sale to third-party purchasers, not to whatever ultimate price WPX obtained further downstream.

The Court's Ruling

The Western District of Texas granted partial summary judgment for WPX on two independent grounds. First, the court held that YMC's lease termination notice failed to comply with the lease's express notice requirements, rendering the termination demand procedurally defective regardless of the underlying merits. Second, the court interpreted the lease's royalty language as entitling YMC only to gross proceeds at the point of sale to third-party purchasers, with the cost-free obligation extending only to that specific delivery point. Under this construction, WPX could properly deduct costs incurred after the third-party sale point.

Implications

The decision addresses the scope of gross proceeds royalty obligations under lease language that references sales to third-party purchasers. The court's interpretation limited the royalty calculation to the initial third-party sale point rather than tracking the hydrocarbons through subsequent transactions. The ruling also underscores the continued importance of precise notice provisions in lease termination disputes.
