Mark A. Doré
Senior Counsel"My diverse journey in the energy sector – ranging from my time as a roughneck, working in the same natural gas refining plant as my father, to my years as a Landman prior to practicing law – has equipped me with a unique perspective. These experiences allow me to offer my clients invaluable understanding into the complexities and nuances required to support their successes, while also providing meaningful and distinctive advice regarding the challenges faced by them, the energy industry, landowners, and stakeholders alike."
As a leading energy industry legal advisor, Mark represents a variety of energy companies in Louisiana and surrounding Gulf Coast region. His practice has included all manner of traditional energy transactional matters, including mineral title examination, due diligence, acquisition and sale of oil and gas properties, and regulatory compliance. He regularly provides advice to fellow attorneys and landmen at both Fortune 500 companies, as well as other business client companies engaged in all types of energy activities. As a practical and trusted legal advisor, Mark’s clients often turn to him to ensure their transactions and other initiatives minimize risk and leverage their opportunities for the most successful outcomes in highly competitive marketplaces.
Most recently, Mark has been advising on the complex legalities associated with carbon capture and storage initiatives, where he regularly works with clients to advise on existing market participation or facilitate their entry into this market. He is also heavily involved in drafting, negotiating, and advising on transactions involving the acquisition of servitude and fee agreements, land use and expropriation issues, and all manner of regulatory matters across all stages of the project.
Notably, Mark was selected by former Louisiana Senator, Brett Allain, to serve on the Task Force on Local Impacts of Carbon Capture and Sequestration called for by Senator Heather Cloud. He is currently an active member of the Lafayette Economic Development Authority, which provides him with first-hand knowledge of and a broader perspective regarding Louisiana’s robust economic development initiatives.

As a team player, Mark is able to bring a wide network of both governmental and business stakeholders together in understanding and navigating complex legislation, energy contracts, and/or regulations specific to Louisiana law and business. He consistently delivers proven project management acumen, essential to handling multiple transactions simultaneously while also ensuring smooth negotiations across all levels of professionals. Mark is retained time and again for his ability to deliver successful outcomes to his client's vital attention to detail when drafting accurate and comprehensive legal documents that protect client interests and support their ROI objectives.
Mark brings a unique background and perspective to serving energy industry clients. Born and raised in Delcambre, Louisiana, Mark grew up in a family who all worked in various areas of the energy industry. He temporarily followed in his father’s footsteps when he worked in the same natural gas refining plant as his father did before him. While attending law school, Mark launched and operated his own oil and gas/real estate title company, while continuing to work full-time as an independent Landman, where he gained a practical knowledge of Louisiana mineral law.
This drive, supported by his multidisciplinary foundation, and his relationships to both industry professionals and governmental stakeholders at all levels, allows Mark to bring value and effectiveness to the benefit of his clients. This enables him to bridge the gap between legal theory and practical, day-to-day application of the law to all types of industry-related endeavors. His distinctive perspective allows him to understand client needs from their point of view, anticipate issues, tailor solutions, and navigate the legal landscape with confidence and clarity.
