State-owned Oil and Natural Gas Corporation (ONGC) is inviting foreign technical services providers to boost declining output at Mumbai High fields. The tender seeks partners with a minimum annual revenue of $75 billion. Selected providers will analyze field performance, propose improvements, and implement technologies to enhance production and recovery. Bids, due by September 15, 2024, must include quotes for quarterly incremental production and revenue share. ONGC aims to tap the field’s remaining reserves of 80 million tonnes of oil and 40 bcm of gas. This move follows previous considerations of stake sales, which faced opposition.
