Managing Environmental Compliance in the Nigerian Oil and Gas Industry: Legal and Operational Perspectives

Environmental compliance management in the oil and gas industry requires the integration of legal obligations, operational safety standards, and corporate governance frameworks. Nigeria's Petroleum Industry Act 2021 introduced significant reforms to environmental liability and regulatory oversight, affecting international oil companies and indigenous operators alike. This study examines how oil and gas companies operating in the Niger Delta region manage environmental compliance obligations under the PIA 2021 and related regulations, focusing on practice in Rivers State and Bayelsa State. A professional management research methodology was adopted, combining structured interviews with HSE managers, legal counsel, and regulatory affairs officers at four upstream oil companies with analysis of NUPRC compliance audit records from 2021 to 2024. Secondary sources include PIA regulatory guidance, NOSDRA enforcement reports, and industry association publications. Findings reveal that compliance management systems vary significantly between multinational and indigenous operators, with smaller local companies frequently lacking dedicated legal compliance functions. The transition from legacy regulatory frameworks to the PIA regime has created interpretive uncertainties that have delayed full compliance implementation. Recommendations include the development of sector-wide PIA compliance management templates, enhanced regulatory capacity at NUPRC for environmental auditing, and mandatory environmental compliance officer certification requirements. This research offers practical guidance for legal and compliance professionals in Nigeria's hydrocarbons sector.
