Kelly Perrier practices in the areas of oil, gas and energy litigation and commercial litigation, particularly focusing on claims of historical and ongoing environmental damage allegedly caused by oil and gas exploration and production activities, commonly referred to as “legacy litigation.” Despite the repetitive framework of many of the petitions, no two defendants have the same facts or defenses; consequently, Ms. Perrier has negotiated and litigated a number of ancillary—yet significant—issues, such as defense and indemnity and insurance disputes for a diverse range of defendants, including historical lessees, current operators, mineral servitude owners, working interest owners, and everyone in between.

Ms. Perrier has represented many independent oil and gas companies in disputes regarding public use of private waterways, compliance notices issued by the Louisiana Department of Environmental Quality, insurance disputes following blow-outs and concursus proceedings against the State of Louisiana, among others.

During law school, Ms. Perrier interned for Chief Judge Burrell J. Carter of the Louisiana First Circuit Court of Appeal. Prior to law school, she worked as a media and political consultant for a small firm handling local and statewide campaigns.
