The Supreme Court has appointed a mediator to settle a long-standing gas migration dispute between the Indian government and Reliance Industries. Investors will watch the process, as the government is seeking $1.55 billion in damages for gas allegedly siphoned from ONGC blocks.
The Supreme Court of India has initiated a mediation process to resolve a long-standing legal battle between the Union government and the Reliance Industries-led consortium regarding gas migration in the Krishna-Godavari (KG) basin. The court appointed former judge Justice Ranjana Prakash Desai to lead the mediation, aiming to settle a dispute that has persisted for over a decade. The government is seeking $1.55 billion in damages, alleging that the Reliance consortium siphoned gas from neighbouring blocks owned by the state-run Oil and Natural Gas Corporation (ONGC).
The core of the dispute involves technical disagreements over how gas moves underground. The government's claim rests on the argument that Reliance exploited gas reservoirs extending into ONGC’s territory. In response, Reliance Industries and its partners, including BP Exploration and Niko Resources, have consistently denied these claims. They argue that the movement of gas between the blocks is a natural physical process caused by pressure differences within the reservoir, similar to osmosis.
The legal history of this case is complex, with multiple shifts in judicial and arbitral opinions. An international arbitration tribunal in 2018 ruled in favour of the Reliance-led consortium, rejecting the government's compensation claim. However, the legal environment became more uncertain in February 2025 when the Delhi High Court set aside a prior single-judge order that had upheld the arbitral award. With the government and the consortium unable to agree through direct dialogue, the Supreme Court has now stepped in to seek an amicable resolution, tasking the mediator with the support of domain experts to evaluate the technical and commercial aspects.
For investors, this mediation process is important as it addresses a potential multi-billion dollar liability. While Reliance Industries is a massive, diversified conglomerate, the outcome of this litigation could clarify the financial impact and provide closure to a long-running dispute that has been an overhang on the KG basin assets. For ONGC, the recovery of claimed damages would be a positive development, though the uncertainty of the outcome remains a factor.
The primary monitorable for shareholders will be the outcome of the mediation and whether both parties can agree on a settlement without further prolonged litigation. The involvement of technical experts in the mediation process suggests that the court is looking for a fact-based resolution to the underlying reservoir management question. Investors should continue to monitor exchange filings for updates on the mediation proceedings, as a final settlement would remove a significant source of legal and financial uncertainty for both energy companies.
