With two decades of litigation experience, Colleen Jarrott represents energy companies in oil and gas, mineral law, carbon capture and sequestration, transportation, and other industries in complex commercial litigation, transactional matters, commercial contracts, and regulatory issues.

In addition, she is well-versed in developing state regulatory and legislative initiatives related to the Louisiana Geologic Sequestration of Carbon Dioxide Act. She regularly represents oil and gas companies before the Louisiana State Mineral and Energy Board, the Louisiana Department of Natural Resources, and the Louisiana Department of Environmental Quality. She also currently serves on the Louisiana Department of Natural Resources' Ad Hoc Committee on Carbon Capture, the Louisiana Oil & Gas Association’s Carbon Capture Committee, and the Carbon Committee of the Louisiana Mid-Continent Oil & Gas Association.

Colleen is a member of Hinshaw's Environmental, Social, and Governance (ESG) group. Her focus on renewable energy and ESG underscores that the energy transition in Louisiana is underway, even as traditional oil and gas exploration and production will continue well into the future on a parallel track.

Fun Facts: Colleen and her husband, Francis, own a 1982 Ericson 25+ sailboat called “Cool Change” (like the song), which they enjoy taking out in Lake Pontchartrain on the weekends. She also enjoys cooking (without recipes). Italian is her favorite. She also enjoys traveling around the world and experiencing different cultures. At home, Colleen is kept in line by her small pack of beasts (three kitties + one adorable corgi named Mable).
