Senior Counsel

Mark Doré is senior counsel in the Lafayette office of Kean Miller. He joined the firm in 2018 and practices in the energy group (oil and gas and renewable energy), business and corporate and real estate groups. One aspect of  Mark’s practice focuses on representing upstream energy companies in Louisiana, including oil and gas transactional matters, mineral title examination, due diligence, acquisition and sale of oil and gas properties, regulatory compliance, and providing advice to attorneys and landmen at companies engaged in upstream activities.

Another facet of Mark's practice is reflected in his experience in the area of Carbon Capture, Usage, and Storage (CCUS). He regularly works with clients to facilitate their entry into this market and has been heavily involved in drafting, negotiation, and advising in connection with the acquisition of servitude and fee agreements, land use and expropriation issues, and regulatory matters in all stages of the project.

While in law school, Mark launched his own oil and gas/real estate title company in Lafayette, Louisiana, and continued working full time as an independent landman from 2004-2010, where he gained hands-on working knowledge of Louisiana mineral law.

Mark is recognized as a 2023 and 2024 Top Lawyer by Acadiana Profile. He was also selected by Louisiana Senator Brett Allain to serve on the Task Force on Local Impacts of Carbon Capture and Sequestration called for by Senator Heather Cloud.
