Legal Framework for Joint Venture Agreements in Nigeria’s Downstream Oil and Gas Sector

Joint venture agreements between Nigerian and foreign entities in the downstream petroleum sector are central to Nigeria's energy infrastructure development, yet disputes over governance, cost recovery, and exit rights generate significant legal complexity. This study examines the legal framework governing joint venture agreements in Nigeria's downstream oil and gas sector, evaluating the Petroleum Industry Act 2021, the Companies and Allied Matters Act 2020, and general contract law as applied to downstream joint venture structures. Using a practitioner-focused methodology, the study analyses 15 joint venture agreements executed between 2018 and 2023, focusing on refinery and gas processing ventures, supplemented by interviews with 25 energy lawyers and 10 energy industry executives in Lagos and Port Harcourt. Findings reveal that joint venture disputes most frequently arise from ambiguous governance provisions, disagreements over capital call obligations, and the exercise of tag-along and drag-along rights upon exit. The study further examines how the Petroleum Industry Act's deregulation provisions affect the commercial viability and legal structuring of downstream joint ventures. Recommendations include the development of model downstream joint venture agreement templates, clear guidance on incorporation vehicles for joint ventures, mandatory dispute resolution escalation clauses, and enhanced regulatory predictability from the Nigerian Midstream and Downstream Petroleum Regulatory Authority.
