Oil and Natural Gas Corporation (ONGC) has signed a Technical Services Contract with BP covering 43 offshore oil and gas blocks in India’s Western Offshore Basin, expanding the companies’ collaboration beyond the Mumbai High field.
The agreement was signed on 25 June 2026 in New Delhi in the presence of India’s Minister of Petroleum and Natural Gas, Hardeep Singh Puri, and Ministry of Petroleum and Natural Gas Secretary Dr Neeraj Mittal.
Under the contract, BP has been appointed as the technical service provider for ONGC’s fields in the Western Offshore Basin. The basin is ONGC’s most productive hydrocarbon-producing basin and has contributed to India’s energy requirements for more than four decades. ONGC said it accounts for approximately 64% of India’s domestic crude oil and natural gas production.
ONGC will retain ownership and operational control of the assets. BP will work with ONGC’s multidisciplinary teams on reservoirs, wells and production facilities to identify and implement measures aimed at moderating natural production decline, improving hydrocarbon recovery, increasing operational efficiency and supporting sustained production growth.
The contract provides for a fixed fee during the first two years, followed by a service fee linked to a percentage of revenue generated from net incremental hydrocarbon production.
The agreement follows the Technical Services Provider contract signed for Mumbai High in February 2025. During the first year of collaboration, the companies said they moderated production decline and delivered growth through optimization of existing wells, enhanced surveillance and reservoir, well and facility-management initiatives.
ONGC Chairman and CEO Arun Kumar Singh said the expanded collaboration would support improved recovery, greater efficiency and sustained production growth.
BP India Chairman and Senior Vice President Kartikeya Dube said the company will bring its expertise to support production from the Western Offshore Basin.
