Nationally ranked Tier 1 in both Energy Law and Oil and Gas Law by Best Law Firms®, Troutman Pepper Locke advises upstream, midstream, and downstream stakeholders on the unique challenges and opportunities in the oil and gas market, including shale and unconventional gas plays across the U.S.
We offer strategic guidance on transactions, regulatory compliance, permitting, financing, and infrastructure development. Our deep experience with federal and state regulations, including oversight by the Federal Energy Regulatory Commission (FERC), allows us to help clients navigate complex regulatory frameworks that are critical for project success and operational security. Our clients rely on us for effective dispute management and our expertise in energy restructuring, bankruptcy, and distressed acquisitions.
Our multidisciplinary approach — integrating legal, regulatory, and policy experience — enables us to deliver tailored solutions at every phase of oil and gas operations. Whether negotiating complex agreements, addressing environmental impacts, or navigating evolving energy policies, we are committed to helping our clients advance sustainable, efficient oil and gas solutions across the industry.
Our services include:

Midstream and Pipeline Infrastructure Development
Our robust midstream practice supports clients in the development, financing, commercialization and regulation of gathering, processing, pipeline and storage facilities. We also are a leader in midstream M&A transactions. We have great depth representing midstream companies in all commercial matters, including gathering and processing agreements, transportation agreements, EPC contracts and real estate matters, while ensuring compliance with key regulations like the Natural Gas Act (NGA) and the Natural Gas Policy Act (NGPA). Our attorneys are experienced in FERC proceedings including NGA Section 7 certificates, NGA Section 4&5 rate cases, section 311 of the NGPA, and handling market access and interconnectivity issues essential for project success.

Leveraging our decades of experience, our team provides extensive support across the oilfield services sector, including mergers and acquisitions, master services agreements, intellectual property licensing, employment matters, and regulatory compliance.
