Caprock DLE has licensed polymer-based technology from Texas Tech University to extract lithium from oil and gas produced water. The company is developing a modular system to process these waste streams, with field operations expected to launch in spring 2027.
Why it matters
Operators in Texas contend with over 25 million barrels of produced water daily and more than $10 billion in annual disposal costs. Extracting lithium presents a potential opportunity to turn a costly waste management challenge into a revenue-generating stream.
Battery-grade lithium carbonate was priced at $19,750 per metric ton as of early September 2026, while Texas operators spend over $10 billion annually on the disposal of 25 million barrels of produced water daily. The long-term commercial yield per unit of water remains unproven.
The players
Caprock DLE
An emerging developer of modular mineral extraction systems for the oil and gas industry.
Texas Tech University
A public research institution that co-owns the polymer-based lithium extraction technology.
Jonathan Grammer
A co-owner of the licensed polymer-based lithium extraction technology.
The details
The technology employs a polymer-based process to isolate lithium directly from the high-volume water streams common in oilfield operations. Caprock DLE is integrating this licensed method with proprietary designs to create a modular unit that can be deployed at existing well sites. This field system aims to minimize infrastructure requirements by fitting into current disposal workflows to capture minerals before the water is handled or treated.
Timeline
2024: Caprock DLE began funding Texas Tech lithium research.
June 2026: The company filed for patent protection on its modular unit.
Summer 2026: Construction began on the first modular unit.
September 2026: Lithium carbonate was assessed at $19,750 per metric ton.
Spring 2027: Field operations are scheduled to commence.
Market Landscape
This development follows the broader industry trend of treating produced water as a potential commodity source rather than a waste management burden. It marks a shift from purely disposal-focused water management to mineral recovery operations in the Permian and surrounding basins.
Operators should monitor the performance of modular extraction units as a potential way to lower net disposal costs through mineral offsets. Decision-makers should evaluate whether their specific produced water streams meet the purity thresholds required for commercial-grade lithium recovery.
The takeaway
The move suggests a future where produced water management is evaluated for both its cost and its mineral content. Operators should track the spring 2027 field launch to determine if these units integrate effectively with existing water handling infrastructure.
What happens next
Caprock DLE is scheduled to initiate field operations in spring 2027.
