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. The Court held that, unless expressly reserved, a deed or lease conveying oil and gas rights also conveys produced water as part of the mineral estate. The decision not only reinforces the ownership of produced water under Texas oil and gas law, but also offers insight into how emerging practices such as direct lithium extraction (DLE) from produced water might be treated under existing legal frameworks.
