State-run Oil and Natural Gas Corporation (ONGC) has taken over operations and control of the disputed Cambay offshore block from Vedanta Oil & Gas Ltd following a Delhi High Court ruling, according to regulatory filings by the two companies.
Vedanta Oil & Gas Ltd has recognised an impairment charge of about ₹379 crore against assets and receivables linked to the block.
The takeover of the CB-OS-02 block took effect on July 22, 2026, after the High Court's single-judge bench dismissed Vedanta's challenge to the government's decision not to extend the production-sharing contract, ONGC said in its quarterly filing.
The block was operated by Vedanta, which held a 40 per cent participating interest; ONGC held 50 per cent, and Invenire Petrodyne Ltd had the remaining 10 per cent.
