India has commenced the technology-testing phase of the ₹84,084 crore Samudra Manthan mission to reduce reliance on energy imports. State-run ONGC is spearheading this initiative with a ₹1 lakh crore investment plan to drill 87 deepwater wells over the next five years. Investors are monitoring this long-term expansion as the company aims to offset natural production declines in older oil fields.
India has officially kicked off the initial technology-testing phase for the Samudra Manthan National Offshore Exploration Scheme. Approved by the government on July 31, 2026, this massive ₹84,084 crore initiative is designed to scale up domestic hydrocarbon production. The mission aims to address the country’s high energy import dependency, with India currently sourcing approximately 85% of its crude oil and half of its natural gas from international markets.
ONGC's Capital Commitment
Oil and Natural Gas Corporation (ONGC) is leading the charge in this sector-wide effort. The company has announced a significant internal investment plan of ₹1 lakh crore to be deployed over the next five years. This capital is earmarked for the drilling of 87 deepwater and ultra-deepwater wells. To support this, the government has introduced a funding mechanism where exploratory wells can receive financial assistance of up to 50% of costs, capped at ₹675 crore per well.
For investors, the recent financial performance of ONGC provides some context on its ability to fund this expansion. The company reported a consolidated net profit of ₹49,793 crore for the fiscal year ending March 2026, marking a 30% increase from the previous year. This profit growth offers a baseline for the company's financial flexibility as it begins to allocate large sums toward high-risk, high-reward offshore projects.
Long-Term Risks and Operational Challenges
While the financial and strategic commitment is significant, the path to commercial output involves several hurdles. Industry standards suggest that deepwater energy projects typically have a long gestation period, often spanning five to 10 years from discovery to actual extraction. This means that while the Samudra Manthan mission is a structural move for energy security, it is unlikely to provide an immediate reduction in import bills.
Additionally, the company faces the operational challenge of natural production declines in its existing, aging oil fields. Sustaining current output levels while simultaneously executing a complex deepwater expansion strategy requires precise capital management. The success of this mission will depend on the technical execution of subsea drilling and the government's ability to maintain clear funding and regulatory support throughout the project lifecycle.
Moving forward, the key monitorables for shareholders will be the progress of the 87 planned wells, the successful procurement of advanced deepwater drillships, and the effective utilization of the government's financial support scheme. Investors will also look for management updates on how the company plans to balance its massive capital spending on offshore exploration with the need to maintain healthy operational margins in its traditional fields.
