Jasper Mason
Senior Counsel
Jasper Mason is a Houston based oil and gas transactions attorney and senior counsel in Dykema’s Corporate Finance practice. He advises exploration and production companies, private equity-backed businesses, investors, and other energy industry participants on acquisitions, divestitures, joint ventures, mergers and acquisitions, and commercial agreements involving upstream and midstream oil and gas assets.
Jasper’s Board Certification in Oil, Gas and Mineral Law by the Texas Board of Legal Specialization and his Certified Professional Landman designation reflect both legal depth and a practical understanding of oil and gas assets. His work teaching Texas Law of Oil and Gas, together with his leadership in prominent bar and energy industry organizations, keeps him closely connected to evolving legal, commercial, and regulatory issues. Clients draw on that perspective when evaluating risk, structuring transactions, negotiating complex agreements, and moving energy projects forward.
Drawing on experience in private practice and senior in-house legal and commercial roles, Jasper understands the legal, operational, and business considerations that shape energy transactions. He advises on conventional and unconventional projects involving onshore and offshore assets, including assets located on state, federal, private, and tribal lands. His experience encompasses joint operating agreements, leasehold and wellbore assignments, ancillary commercial contracts, due diligence, regulatory obligations, and agreements governing mineral and surface access.
Jasper has worked on domestic and international energy projects involving producing and prospective properties across major U.S. oil and gas regions. He also has experience addressing royalty and joint-interest billing issues, negotiating rights-of-way and easements, and working with government agencies and industry participants on matters affecting exploration and production operations.
