Scott O’Connor serves as Chair of the Oil & Gas Section for the Firm. Scott’s practice focuses on oil and gas and complex commercial litigation. He handles matters involving sales, purchases and exchanges of oil and gas assets, negotiations of leases, operating agreements, participation agreements, farmouts, farm-ins, and other agreements used in the oil and gas industry. He has litigated and arbitrated numerous disputes involving onshore and offshore operating agreements, mineral servitudes and leases, purchase and sale agreements, title disputes, royalty claims, gas balancing agreements, farmout agreements, decommissioning obligations, environmental and toxic tort claims, lien and security rights, partitions of co-owned property, preferential purchase rights, pipeline transportation agreements, severance tax claims and unit agreements. He has defended national and state class actions involving oil and gas pricing practices, including antitrust litigation, and he has represented oil and gas clients as creditors and debtors in bankruptcy proceedings and claimants in concursus and interpleader actions.
In 2023, the prestigious Chambers USA: America’s Leading Lawyers for Business again recognized Scott for the area of Energy & Natural Resources: Oil & Gas, saying, “[Scott] is chair of the oil and gas practice at the firm and is well regarded for his representation in sector-specific litigation.” Sources have been quoted as saying, “He is an outside-the-box thinker and is meticulous,” and “Scott is very thorough and thoughtful and does a really good job of laying out all your options.”
Scott joined the firm in 1990 after clerking for the Honorable A. J. McNamara, former Chief Judge of the U.S. District Court for the Eastern District of Louisiana. During law school, Scott was a member and Managing Editor of the Loyola Law Review and a member of the Moot Court staff.
