Spudding of first appraisal well, MN-DWN18-1-HD, begins in Mahanadi offshore basin

Key Highlights:

• Drilling commenced for the first appraisal well, MN-DWN18-1-HD, in the Mahanadi Offshore Basin.
• Union Minister Shri Hardeep Singh Puri marked the start, highlighting it as a step towards India's energy security.
• This is the first of four planned deepwater wells aimed at systematically evaluating a prospective offshore basin.
• The initiative seeks to unlock new hydrocarbon resources and strengthen India's domestic production capability.
• It reflects the outcome of policy and regulatory reforms in India's exploration and production sector.

Detailed Insights:

• The government has fundamentally transformed the exploration and production ecosystem through landmark policy and regulatory reforms over the past decade.
• Key reforms include the introduction of the Hydrocarbon Exploration and Licensing Policy (HELP) and the Open Acreage Licensing Programme (OALP).
• The OALP replaced the nomination-based approach with a transparent Revenue Sharing framework.
• Nearly 99% of erstwhile offshore "No-Go" areas have been opened for exploration, boosting investor confidence.
• Approximately 81% of India's active exploration acreage has been awarded after 2014.
• Sustained investments in geoscientific data generation include initiatives like Mission Anveshan and the National Seismic Programme.
• Under OALP, 172 exploration blocks covering 3.8 lakh sq km have been awarded, with committed investments exceeding USD 4.3 billion.
• In FY 2025-26, 674 wells were drilled, leading to five new discoveries and seven monetized discoveries.
• The government's strategy focuses on discovering new hydrocarbon resources and maximizing recovery from existing fields using advanced technologies.
• This effort aims to reduce import dependence, strengthen self-reliance, and contribute to the vision of Viksit Bharat.
• ONGC, Oil India Limited, and the Directorate General of Hydrocarbons are key entities involved in these exploration efforts.

Key Concepts Involved:

• Appraisal Well: A well drilled after a discovery to determine the size, characteristics, and commercial viability of a hydrocarbon reservoir.
• Hydrocarbon Exploration and Licensing Policy (HELP): A policy framework introduced in 2016 to boost exploration and production of oil and gas in India.
• Open Acreage Licensing Programme (OALP): A system allowing companies to carve out exploration blocks from a designated area, rather than bidding on pre-defined blocks.
• Viksit Bharat: A vision for India to become a developed nation by 2047, encompassing economic growth, social progress, and environmental sustainability.
