Union Petroleum Minister Hardeep Singh Puri on Saturday, 25 July 2026 hailed the commencement of drilling operations at the first appraisal well in the Mahanadi offshore basin as a historic step toward energy self-reliance, crediting the move to a decade of upstream policy reforms under Prime Minister Narendra Modi. The spudding, conducted under the 'Samudra Manthan' programme, was marked at an event in New Delhi attended by officials of state-run explorer ONGC.

Context

Puri's post, written in Hindi, described the development as 'ऊर्जा सुरक्षा की दिशा में भारत का एक और ऐतिहासिक कदम' — 'another historic step for India in the direction of energy security.' He said every metre drilled would bring the country closer to reducing import dependence, strengthening self-reliance, and realising the vision of a 'Viksit Bharat' (Developed India). The well in question is the first appraisal well to be spudded in the basin under the current offshore exploration push, with ONGC leading operations.

The Mahanadi offshore basin, located off the coast of Odisha in India's eastern offshore, is among the sedimentary basins that were opened for exploration following regulatory changes introduced between 2016 and 2018. India currently imports more than 80 per cent of its crude oil requirements, making domestic upstream discoveries a strategic priority.

Policy Backdrop

Puri specifically cited four pillars of reform that he said transformed the exploration and production (E&P) sector over the past decade. The Hydrocarbon Exploration and Licensing Policy (HELP), notified in March 2016, replaced the earlier production-sharing contract regime with a simpler revenue-sharing model, reducing government intervention in operational decisions. The Open Acreage Licensing Policy (OALP), launched in July 2016, enabled companies to nominate and bid for exploration blocks on a continuous basis rather than waiting for government-initiated rounds.

Complementing these was a transparent revenue-sharing framework and, critically, the opening of approximately 99 per cent of India's offshore acreage — previously restricted — for exploration. Puri described these steps as collectively giving India's energy sector 'a new direction.' The 'Samudra Manthan' event in Delhi served as the ceremonial occasion to mark the spudding milestone.

Stakeholders and Impact

ONGC, India's largest public-sector upstream company, is the primary operator for the Mahanadi offshore drilling. A successful appraisal campaign in the basin could add to India's proven reserve base and reduce the country's exposure to volatile global crude prices. Private and foreign E&P investors who have participated in OALP bidding rounds also stand to benefit from the regulatory environment that the government says now governs nearly all of India's sedimentary acreage.

Broader stakeholders include domestic refiners and consumers, for whom reduced import dependence would mean lower vulnerability to supply disruptions and currency outflows. India's crude import bill runs into hundreds of billions of dollars annually, making even incremental domestic production gains economically significant.

What's Next

The commercial outcome of the appraisal well will be closely watched by the upstream industry. A discovery of commercial scale in the Mahanadi basin would validate the policy reforms and could trigger follow-on development investment. The government is also expected to continue successive OALP bidding rounds to further expand the active exploration portfolio. Puri's framing of the event as 'the beginning of a new chapter' signals that the ministry intends to use such milestones to sustain momentum on the broader energy-security agenda ahead of India's long-term goal of cutting import dependence.
