Greg Duplantis’ legal practice centers on oil and gas property title examination with an emphasis on analyzing and rendering complex opinions concerning title that is held by production. He regularly calculates varying royalty interests, overriding royalty interests and proportionately burdened net revenue interests.

Greg has extensive experience drafting agreements and contractual provisions on behalf of both operating and non-operating working interest owners, including drafting and negotiating provisions for joint operating agreements, drilling contracts, master services contracts, unit and commingling agreements, gas sales, processing and marketing agreements, onshore and offshore facilities use agreements, mineral leases, subleases and assignments, seismic permits, rights-of-way, servitudes, surface and subsurface agreements, Form B’s, federal communitization agreements and other related transactional documents and contracts.

Greg frequently represents clients before Louisiana state agencies, including the Office of Conservation and Office of Mineral Resources, regarding oil and gas related matters such as unitization, state leasing, commingling and pipelines. He also has experience rendering “stand up” title opinions that require physically searching the indices of courts’ conveyance records and executing opinions on site.

Greg earned both his undergraduate and law degrees from Louisiana State University, where he was a four-time letter winner in pole vaulting. Following his graduation, he excelled as a world-class professional pole vaulter, becoming a four-time U.S. Olympic Trials Qualifier. Greg, who is fluent in Swedish, met his wife Helena while both were competing on the LSU Track and Field Team. Greg and Helena currently reside in Lafayette, Louisiana, where Greg serves as a volunteer assistant track and field coach at the collegiate and high school levels. He is a “National Lead Coach” and frequent lecturer at the National Pole Vault Summit and was recently inducted into the Louisiana High School Athletic Association Hall of Fame. He and his wife Helena are proud parents of their four children, Andreas, Antoine “Twani”, Armand “Mondo” and Johanna Duplantis.
