India is preparing for a major expansion of offshore oil and gas exploration through the Samudra Manthan – National Offshore Exploration Scheme, an ambitious programme aimed at discovering and developing the country’s offshore energy resources.The initiative focuses on exploring deepwater and ultra-deepwater regions, where large quantities of oil and natural gas may remain undiscovered. The programme is expected to use advanced exploration technologies, including large-scale seismic surveys, geological studies and scientific drilling, to identify promising offshore resources.The Union Government has approved an estimated ₹84,084-crore investment for the scheme through FY 2030–31. The programme is intended to accelerate exploration activity and encourage greater participation in India’s offshore energy sector.A major component of Samudra Manthan is the systematic mapping of India’s offshore sedimentary basins. Modern 2D and 3D seismic surveys will help identify geological structures beneath the seabed that could contain hydrocarbons.Deepwater exploration is technically challenging and requires specialised equipment, advanced vessels, sophisticated data analysis and highly skilled personnel. The scheme aims to strengthen these capabilities and create a more advanced domestic offshore exploration ecosystem.
India remains heavily dependent on imported crude oil and natural gas to meet its growing energy requirements. Increasing domestic exploration and production could help reduce import dependence and strengthen the country’s long-term energy security.The government expects the programme to contribute significantly to the country’s domestic resource base, with the potential to add more than 600 million metric tonnes of oil equivalent (MMTOE) through additional exploration and resource development.Samudra Manthan is also expected to support the development of Indian capabilities in offshore exploration technology. Greater use of domestic equipment, services and expertise could create opportunities for Indian companies involved in engineering, technology, marine services and energy infrastructure.The initiative could therefore extend beyond oil and gas discovery, helping develop a wider ecosystem around India’s offshore energy industry.
Advanced geological and geophysical technologies will play an important role in the programme. High-resolution seismic data can help scientists and exploration companies better understand underground formations and identify areas that warrant further investigation.Scientific drilling and improved interpretation of geological data can then help determine whether potential discoveries are commercially viable.Large-scale offshore exploration can generate activity across several sectors, including engineering, shipping, offshore construction, equipment manufacturing and specialised technical services.The programme could also create new opportunities for Indian businesses and skilled professionals while supporting investment in the country’s energy infrastructure.
With energy demand expected to remain high as India’s economy expands, offshore resources could become an important part of the country’s future energy mix. Samudra Manthan represents a strategic attempt to explore these resources using modern technology and large-scale investment.The success of the programme will ultimately depend on the results of exploration, the commercial viability of discoveries, technological execution and responsible management of offshore operations.Samudra Manthan therefore marks an important phase in India’s search for greater energy self-reliance, stronger offshore capabilities and a more secure domestic energy future.
