Together, the two attorneys further strengthen Dykema’s capabilities in Houston across sophisticated energy transactions and complex litigation.

“Jasper and Warren are outstanding additions whose experience aligns extremely well with the needs of our clients and the strategic plan for the continued growth of our Houston office,” said Isaac Villarreal, Managing Member of Dykema’s Houston Office. “Jasper brings a deep understanding of the oil and gas industry from both the legal and business sides, while Warren adds significant trial experience defending companies in complex, high-stakes litigation. Their arrival strengthens two important areas of our Houston platform and further enhances our ability to serve clients throughout Texas and nationally.”

Drawing on his combination of legal and commercial experience, Mason advises clients on conventional and unconventional energy projects involving onshore and offshore assets. His work includes joint operating agreements, leasehold and wellbore assignments, ancillary commercial agreements, due diligence, regulatory obligations, mineral and surface access, and other matters affecting exploration and production operations. He has represented clients in significant transactions involving assets across major U.S. oil and gas regions, including a strategic partnership in the Permian Basin with an enterprise value exceeding $3 billion.

Mason is Board Certified in Oil, Gas, and Mineral Law by the Texas Board of Legal Specialization and is a Certified Professional Landman through the American Association of Professional Landmen. He has also served as an adjunct professor at the University of Houston Law Center since 2018, teaching Texas Law of Oil and Gas.
