Dykema has expanded its Houston office with the addition of Jasper Mason and Warren B. Wise, each joining the national law firm as Senior Counsel.
Mason joins Dykema’s Corporate Finance Practice Group and will work closely with the firm’s Oil & Gas team, while Wise joins the Product Liability and Class Action Litigation practice group. The additions strengthen Dykema’s Houston capabilities across energy transactions and complex civil litigation.
Mason 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.
His background includes both private practice and senior in-house legal and commercial roles, including positions with Marathon Oil Corporation and Gibson, Dunn & Crutcher.
Mason’s experience covers conventional and unconventional energy projects involving onshore and offshore assets. His work includes joint operating agreements, leasehold and wellbore assignments, commercial agreements, due diligence, regulatory obligations, mineral and surface access issues, and other matters related to exploration and production operations.
He has represented clients in significant transactions involving 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 taught Texas Law of Oil and Gas as an adjunct professor at the University of Houston Law Center since 2018.
Wise joins Dykema from MehaffyWeber, where he was a shareholder with an active trial practice. He represents businesses and individuals in complex civil matters involving product liability, commercial vehicle and trucking accidents, workplace injuries, toxic torts, construction disputes, personal injury, and wrongful death claims.
His experience includes representing construction companies, energy and oil-and-gas businesses, and other corporate clients in high-exposure litigation. Wise has handled first-chair jury trials, arbitration proceedings, dispositive motions, and appellate matters and has secured favorable verdicts and summary judgments in cases involving multimillion-dollar claims.
Dykema opened its Houston office in 2022, adding to existing Texas offices in Dallas, Austin, and San Antonio. The firm has continued expanding its Houston presence across energy, corporate and finance, restructuring and bankruptcy, labor and employment, immigration, healthcare, real estate, construction, and litigation.
