Mumbai, January 14, 2026 – Indian Oil Corporation Limited (IOC), in partnership with Bharat PetroResources Limited, has reported multiple oil discoveries in Onshore Block 1 in Abu Dhabi, marking a significant milestone in India’s public-sector energy companies’ overseas upstream operations.
The two companies jointly operate the Onshore Block 1 exploration concession through their equal joint venture, Urja Bharat Pte Limited, which secured the block in Abu Dhabi’s 2019 bid round. The latest discoveries reinforce the block’s hydrocarbon potential across both unconventional and conventional reservoirs.
Unconventional Shilaif Play Shows Strong Results
The first discovery was made in the unconventional Shilaif play through the XN-76 exploratory well. Following successful hydro-fracturing operations, the well flowed light crude oil to the surface from the Shilaif formation. The test results have confirmed the presence of unconventional oil resources within the concession area.The joint venture is encouraged by the performance of the well and plans to move ahead with appraisal activities to further establish the economic deliverability of the reservoir.
First Oil Find in Habshan Reservoir
In a separate development, Urja Bharat also recorded an oil discovery during testing of exploratory well XN-79 02S. The well flowed light crude oil, making it the first oil find in the Habshan reservoir within Onshore Block 1.This discovery is expected to undergo detailed appraisal and maturation to assess its potential for commercial development, adding another prospective layer to the block’s resource base.
Strategic Significance for Indian PSUs
The discoveries represent a notable achievement for Indian Oil and Bharat PetroResources as international upstream operators, strengthening their presence in one of the world’s most prolific hydrocarbon regions. Beyond these finds, the joint venture is also progressing development plans for the existing Ruwais field and continuing exploration of additional hydrocarbon prospects within the concession area.The positive drilling outcomes underline the growing role of Indian public-sector energy companies in overseas exploration and production, supporting long-term energy security through diversified international assets.
