ONGC kicks off deep‑water drilling in Mahanadi Basin – India’s ‘Samudra Manthan’ energy push begins

New Delhi – On a quiet Saturday morning, the Indian government quietly but proudly announced that the country has entered what officials are calling its “next energy frontier.” The announcement centred on ONGC’s commencement of deep‑water exploratory drilling in the Mahanadi Offshore Basin, a region that until now has been largely untapped.

Union Petroleum Minister Hardeep Singh Puri, perched behind his laptop, gave the virtual nod to drill the first well – labeled MN‑DW18‑1‑H‑D – and posted a short note on X. In his post, he called the exercise the kickoff of the Samudra Manthan mission, a sweeping drive to tap India’s offshore oil and gas riches.

“India’s next energy frontier is deep waters,” Puri wrote, adding that each prospect evaluated, each well drilled, and each discovery made will help lift domestic production, trim the country’s reliance on imports, and shore up energy security. He linked the effort directly to Prime Minister Narendra Modi’s broader vision of self‑reliance in energy.

The Petroleum Ministry says this is just the first of four deep‑water wells slated for the Mahanadi basin. Using state‑of‑the‑art drilling rigs, ONGC will systematically probe the basin’s hydrocarbon potential. The ministry points out that India’s eastern and western offshore basins, where water depths can exceed 3,000 metres, are estimated to hold more than 5,600 million metric tonnes of oil‑equivalent – a staggering amount that could transform the country’s energy mix.

Recent successes in the Cauvery, Mahanadi and Andaman basins have given the sector a fresh burst of confidence. Officials note that the current drive rests on a decade of policy reforms – the Hydrocarbon Exploration and Licensing Policy, the Open Acreage Licensing Programme, and the opening up of nearly 99 % of previously designated “No‑Go” offshore areas.

While the first well is only the beginning, the government is hopeful that the Samudra Manthan campaign will, over time, lift domestic hydrocarbon output significantly and lessen India’s chronic dependence on imported oil and gas. As the rig churns away in the deep blue, the nation watches, hopeful that the next big discovery may be just beneath the waves.
