The burgeoning demand for lithium, spurred by decarbonization targets and the rise of electric vehicles, is opening new avenues for extraction through Direct Lithium Extraction (DLE) in the Gulf of Mexico region. This shift presents unique legal challenges and opportunities rooted in Texas law, particularly for landowners and oil and gas operators exploring lithium extraction potential in produced water—a byproduct of oil and gas drilling operations.
Texas stands out as a primary area of interest due to its rich lithium brine resources, notably in regions like the East Texas Smackover formation. Companies such as Standard Lithium Ltd., alongside its partner Equinor, have already secured substantial Department of Energy funding to develop DLE facilities in the area [Standard Lithium]. Similarly, Exxon Mobil has embarked on lithium projects within the formation, illustrating the region’s potential in this emerging field [Exxon Mobil 2023 Announcement].
Despite these developments, the absence of a comprehensive legal framework specifically governing DLE in Texas introduces uncertainty for stakeholders. A critical legal question pertains to the ownership of lithium and royalty interests: is lithium classified as part of the mineral estate, or does it belong to the surface estate? Historically, Texas law permits a division between mineral and surface estates, a distinction that informs ownership and rights to proceeds from minerals [Texas Law].
The potential characterization of lithium as a mineral estate is reinforced by Texas precedents, such as Moser v. US Steel Corp, which broadly considers lithium as a mineral based on its ordinary meaning [Moser v. US Steel Corp]. However, this mineral-centric view could clash with Texas water law, especially given the existing legal distinction between groundwater—owned by surface owners—and produced water, which recent rulings have placed within the mineral estate.
The issue further complicates when considering DLE’s accommodation-doctrine implications, exemplified by Coyote Lake Ranch v. City of Lubbock, where surface-use obligations were established between landowners and groundwater rights holders [Coyote Lake Ranch Case]. This doctrine becomes pivotal in scenarios where lithium extraction might necessitate consideration of separate interests under concurrent oil and gas leases.
With the Texas Supreme Court expected to weigh in on related disputes like Cactus Water Services v. COG Operating, legal clarity remains in flux. Industry participants are advised to clearly delineate ownership and surface-use rights within DLE agreements to navigate the evolving legal landscape and mitigate potential conflicts as the market for lithium extraction develops in Texas.
