Appeal Court Affirms Halkin E&P’s Ownership of Atala Marginal Field, Bolstering Regulatory Integrity
The Federal Court of Appeal in Port Harcourt has definitively affirmed Halkin Exploration and Production Limited’s legal ownership and operational rights over the Atala Marginal Oil Field (OML 46) in the Niger Delta. This landmark decision upholds a 2025 ruling by the Federal High Court in Yenagoa, bringing a significant legal dispute to a close and reinforcing the integrity of Nigeria’s upstream regulatory processes.
A three-member panel, led by Justice Mohammed Sirajo, dismissed an appeal lodged by Bayelsa Oil Company Limited, deeming it unmeritorious. The appellate court also awarded costs of N1 million against the appellant in favour of the four defendants. This judgment effectively terminates Bayelsa Oil Company’s challenge to the re-awarding of OML 46 to Halkin E&P, a process initially contested in the Federal High Court and subsequently appealed.
The Court of Appeal’s ruling rested on two key findings: that Bayelsa Oil Company’s case was statute-barred, and crucially, that the company lacked the legal standing to challenge Halkin E&P’s established ownership and operational rights. This dual finding significantly curtails any further legal avenues for Bayelsa Oil Company to reclaim the asset through the courts.
This protracted legal battle has been closely monitored within Nigeria’s upstream oil sector, a segment frequently subject to scrutiny regarding the processes governing the bidding and reallocation of marginal field licenses. The Nigerian Upstream Petroleum Regulatory Commission (NUPRC), which oversaw the re-awarding of OML 46 to Halkin E&P, has consistently defended the transparency and fairness of its procedures.
Reacting to the judgment, Chikaosolu Ojukwu, Senior Advocate of Nigeria representing the NUPRC, described the ruling as a “victory for the upstream oil and gas sector.” He emphasised that the outcome, delivered a year after the High Court’s initial decision, reaffirms the “seriousness and integrity of the bidding and re-awarding process” managed by the NUPRC.
Marginal fields, typically smaller deposits overlooked by major international oil companies, represent an increasingly vital component of Nigeria’s oil production base, particularly as large multinational operators divest onshore assets. The government has actively sought to promote indigenous participation in this segment through licensing rounds and reallocation exercises. The Atala field has been a prominent example of the competing claims that can arise within this dynamic sector.
While neither Halkin E&P nor Bayelsa Oil Company have issued immediate public statements, it remains to be seen whether Bayelsa Oil Company will pursue a further appeal to the Supreme Court. The NUPRC’s ongoing efforts to boost domestic participation in the oil and gas sector through successive marginal field licensing rounds underscore the strategic importance of such regulatory clarity and legal certainty for investors and operators alike.
