Willkie Farr & Gallagher LLP has a standout oil and gas team, representing clients across the upstream, midstream, and downstream sectors, including the midstream and LNG value chain. The team regularly advises on the acquisition and divestiture of upstream and midstream assets, forming energy-focused private equity funds, restructuring of distressed assets, and regulatory matters before governing bodies. The Houston and Dallas-based Archie Fallon, experienced in platform investments, M&A, financings, joint ventures, and project development, leads the team alongside Dallas-based Sarah McLean, a leader in the private equity sphere with an emphasis in the energy sector. Joining the team’s Dallas office in April 2025, Lawrence Hall and Jonathan Platt bolster the practice’s ability with private equity-backed companies and corporate energy transactions. Tan Lu is a notable practitioner in Houston, focused on upstream and midstream acquisitions, disposals, and drilling and oilfield services.
