On June 27, 2025, the Texas Supreme Court issued its long-awaited decision in Cactus Water Services, LLC v. COG Operating, LLC, No. 23-0676, resolving a high-stakes dispute over the ownership of produced water—a vexing byproduct of oil and gas production that is increasingly being viewed as a resource rather than waste—and its constituents.
