Fellers Snider has decades of experience handling complex legal matters for clients in the energy, environmental, and natural resources sectors. Our attorneys bring diverse backgrounds—including service in the judiciary, at the Oklahoma Corporation Commission, and in leadership roles at Fortune 500 companies—giving us practical insight and strong problem-solving capabilities for high-stakes disputes in this industry.

Energy Transactions

We assist clients with transactions involving the lease, purchase, or sale of oil and gas properties, equipment, facilities, and business entities. Our work covers every stage of a deal, from due diligence and environmental assessments to drafting and negotiating contracts and addressing post-transaction compliance issues. We prepare and negotiate service contracts, purchase and sale agreements, access agreements, and agreements involving the handling, treatment, and remediation of hazardous substances and wastes.

Litigation

Our attorneys represent clients in a wide range of energy and environmental disputes, including:

• Natural gas transportation, gathering, purchase, and sale issues
• Exposure claims from discontinued or divested operations
• Royalty disputes
• Environmental claims, including class actions tied to exploration, production, pipelines, disposal facilities, and surface damage
• Reservoir damage and drainage disputes
• Right-of-way, franchise, and condemnation matters involving royalty and working interests
• Oil and gas-related class actions and shareholder derivative suits
• Personal injury or wrongful death claims alleging exposure to toxic substances
• Indemnity and contractual disputes allocating environmental responsibility in major acquisitions and divestitures
• Oil and gas-related business tort litigation

We also handle enforcement actions brought by federal and state agencies, natural resource damage claims, citizen suits, and cases under CERCLA, RCRA, and other statutory provisions. Our experience allows us to help clients assess operations, manage risk, and avoid regulatory disputes before they lead to litigation.

Administrative and Regulatory Matters

We advise clients on federal, state, and local environmental statutes and regulatory requirements affecting their operations. Our attorneys represent clients in administrative proceedings, negotiate with agencies, and help structure business activities to reduce exposure to costly compliance disputes. We guide clients through environmental permitting, audits, corrective actions, and remediation planning for new, existing, or expanding facilities. We also assist clients in monitoring and influencing proposed legislation or rulemaking that could impact their operations.
