For 120 years, Thompson & Knight has counseled oil, gas, and energy industry clients – those who explore, develop, produce, finance, store, market, transport, and process energy resources. We are one of the only large law firms in the United States with a separate Oil and Gas Practice Group, and more than 85 percent of Thompson & Knight’s attorneys have worked on energy industry matters. Furthermore, many of the Firm’s attorneys have prior industry experience, including as petroleum engineers, in-house counsel, auditors, landmen, and bankers. As a result, we not only provide our clients with an integrated service through the collaboration of attorneys across multiple practice areas, but each of these attorneys also truly understands the energy industry.

Thompson & Knight maintains an “active energy and natural resources department with recognized expertise in the oil and gas sector.” – Chambers Global 2018

The Firm’s clients include multi-national and independent oil and gas companies, host government oil and gas companies, private power plants, energy industry service giants, refineries, petrochemical companies, financial institutions, and multi-national drilling contractors and construction companies. We have represented these industry clients through decades of highs and lows in the market, and our attorneys cover sophisticated transactions as well as day-to-day operational issues.

In addition to being named “Law Firm of the Year” in Natural Resources Law (2018) and Oil & Gas Law (2011-2013, 2015, 2017) by U.S. News – Best Lawyers® “Best Law Firms,” the Firm’s oil, gas, and energy practice is also recognized by numerous other prestigious legal directories, including:
