ONGC Expands BP Partnership To Lift Output From Western Offshore Fields
State-run ONGC has widened its ONGC BP partnership to boost oil and gas output from India’s Western Offshore Basin. The two signed a new technical services contract on June 25, 2026. Under it, British energy major BP will help ONGC pump more from a group of ageing but vital offshore fields. The deal builds on early success at the famous Mumbai High field.
An “offshore basin” is a large area under the sea where oil and gas are found. The Western Offshore Basin has been ONGC’s main producing region for over four decades. It includes 43 blocks. A “block” is a marked area of seabed given out for exploring or producing oil and gas. This basin alone accounts for about 64% of India’s own crude oil and natural gas output.
What the new contract covers
BP will act as a technical services provider. That means BP brings its know-how, tools and methods to help ONGC get more out of existing fields. This is not a sale of the fields. ONGC keeps ownership. BP simply helps run them better.
The payment is built to reward results. In the first year, BP gets a fixed fee. After that, BP earns a performance-based fee linked to the extra oil and gas produced because of its work. So the more BP helps lift output, the more it earns. This ties BP’s reward directly to India’s gains.
Building on the Mumbai High success
BP was first brought in for Mumbai High in 2025. Mumbai High is one of India’s biggest and oldest offshore oil fields. Old fields tend to produce less over time, a problem called “natural decline.” In its first year there, BP helped slow that decline.
The gains came from steps like well optimisation and better reservoir surveillance. “Well optimisation” means tuning each well so it produces as much as possible. “Reservoir surveillance” means closely watching the underground oil and gas pool to manage it wisely. After these results, ONGC chose to extend BP’s role across the wider basin.
Key facts
| Item | Detail (as reported) |
|---|---|
| Partners | ONGC and BP |
| Contract signed | June 25, 2026 |
| Area covered | Western Offshore Basin (43 blocks) |
| Share of India’s output | About 64% of domestic crude and gas |
| First-year payment | Fixed fee |
| Later payment | Performance-based on extra output |
| Earlier scope | Mumbai High (BP since 2025) |
The signing took place in the presence of Union Petroleum and Natural Gas Minister Hardeep Singh Puri and Petroleum Secretary Dr Neeraj Mittal. Their presence shows how important the government sees this output push.
Why it matters (especially for India and founders)
India imports most of the oil it uses. That costs huge amounts of foreign currency and leaves the country exposed to global price swings. Squeezing more output from existing fields cuts the need to import and supports energy security.
For businesses and founders, steadier home-grown energy can mean more stable fuel and power costs over time. It also shows India teaming up with global experts to modernise its core industries. This sits within a broader trend of large infrastructure and energy bets, much like Tata Power’s Rs 15,000 crore grid upgrade in Mumbai.
FAQ
Is ONGC selling its fields to BP?
No. ONGC keeps ownership. BP is only a technical services provider that helps run the fields better in return for a fee.
How will BP be paid?
BP gets a fixed fee in the first year. After that, its fee is performance-based, linked to the extra oil and gas produced because of its work.
Why is the Western Offshore Basin so important?
It has been ONGC’s main producing region for over 40 years and accounts for about 64% of India’s own crude oil and natural gas output.
The takeaway is that ONGC is bringing in BP’s global expertise to slow decline and lift output from India’s most important offshore fields. If it works across the basin like it did at Mumbai High, India could pump more of its own oil and gas and lean less on imports.
