New Delhi: Oil and Natural Gas Corporation (ONGC) has brought bp on board to enhance oil and gas production from its fields in the Western Offshore Basin, expanding a technical partnership that until now covered only the Mumbai High field. The two companies signed a Technical Services Contract on Thursday, appointing bp as the technical services provider (TSP) for Western Offshore Basin, ONGC's most prolific, in the presence of Minister of Petroleum and Natural Gas Hardeep Singh Puri and Petroleum Secretary Dr Neeraj Mittal.

The contract follows the technical services provider (TSP-1) contract for Mumbai High and marks an expansion of the ONGC-bp collaboration to the wider Western Offshore Basin. ONGC said the deal will enable wider deployment of advanced technologies, global technical expertise and best-in-class operating practices across some of India's most important mature hydrocarbon assets.
The Western Offshore Basin comprises 43 blocks and is ONGC's most prolific hydrocarbon-producing basin, having contributed to India's energy requirements for over four decades. As India's national oil company, ONGC accounts for approximately 64 percent of the country's domestic crude oil and natural gas production.
ONGC will retain complete ownership and operational control of the assets. Global major bp will work with ONGC's multidisciplinary teams to identify and implement focussed interventions across reservoirs, wells and production facilities. The collaboration aims to moderate natural production decline, improve hydrocarbon recovery and operational efficiency, and support sustained production growth.
Under the terms of the contract, bp will receive a fixed fee for the first two years, followed by a service fee linked to a percentage share of revenue generated from net incremental hydrocarbon production.
The agreement builds on the Technical Services Contract signed by ONGC and bp for Mumbai High in February 2025. During the first year of that collaboration, the two companies moderated production decline and delivered growth through optimisation of existing wells, enhanced surveillance and focused reservoir, well and facility-management initiatives.
ONGC Chairman and CEO Arun Kumar Singh said, "Building on the encouraging outcomes at Mumbai High, this expanded collaboration will support improved recovery, greater efficiency and sustained production growth."
Oil major bp India Chairman and bp Senior Vice President Kartikeya Dube said, "We look forward to bringing bp's global expertise to support enhanced production from the Western Offshore Basin and strengthen India's energy security."
