ONGC and Oil India Embark on Rs 3,200 Crore Offshore Exploration with BP's Expertise
ONGC and Oil India are initiating a Rs 3,200 crore stratigraphic drilling campaign in untapped offshore areas, set to begin in early 2026. The project aims to boost India's domestic hydrocarbon production and reduce import dependency. Four deep-sea wells will be drilled across the Andaman, Mahanadi, Saurashtra, and Bengal Basins. BP will provide technical expertise for the project. The government will compensate ONGC and Oil India for campaign costs. This initiative aligns with India's strategy to reduce its oil and gas import bill, currently at about $150 billion annually.

State-run oil explorers Oil & Natural Gas Corporation (ONGC) and Oil India Ltd are set to launch an ambitious Rs 3,200 crore stratigraphic drilling campaign in untapped offshore areas. The initiative, slated to commence in early 2026, aims to bolster India's domestic hydrocarbon production and reduce its substantial import dependency.
Exploration Strategy
The campaign's first phase involves drilling four wells in deep-sea areas across diverse sedimentary basins:
- Andaman Basin
- Mahanadi Basin
- Saurashtra Basin
- Bengal Basin
ONGC plans to utilize its available rig for the drilling operations, which are expected to begin in early 2026.
BP's Technical Expertise
In a significant move, British oil major BP will provide technical expertise for the project. BP's role will be crucial in:
- Identifying optimal drilling locations
- Supporting drilling operations
The Indian government has agreed to compensate both ONGC and Oil India for the campaign costs, including BP's service fees.
Stratigraphic Drilling: Unveiling Geological Secrets
The primary objective of stratigraphic drilling is to study underground geological formations. This exploration technique helps determine whether areas contain commercially viable hydrocarbon resources. Each stratigraphic well is estimated to require:
- Three months for drilling
- Three to four quarters for results interpretation
Government Ownership and Future Plans
Currently, the government owns the blocks where drilling will take place. Any discoveries made during this campaign will be subject to government decisions on monetization methods.
Reducing Import Dependency
This exploration initiative aligns with India's broader strategy to reduce its hefty oil and gas import bill. Key statistics highlight the importance of this campaign:
Metric | Value |
---|---|
Oil import dependency | 88% |
Natural gas import dependency | 50% |
Current oil and gas import bill | ~$150 billion |
By increasing domestic production, the government aims to significantly cut down on these import expenses.
Timeline and Expectations
With drilling set to commence in early 2026, the results of this extensive exploration campaign are eagerly anticipated by the energy sector. The findings could potentially reshape India's domestic oil and gas landscape, paving the way for reduced import dependency and enhanced energy security.
As this strategic initiative unfolds, it marks a significant step in India's quest for energy self-sufficiency, combining state-run expertise with international technical knowledge in the exploration of promising offshore reserves.
