📌 Summary:

• Union Petroleum Minister Hardeep Singh Puri marked the spudding (start of drilling) of the first appraisal well, MN-DWN18-1-HD, in the Mahanadi Offshore Basin — the first of four planned deepwater wells to systematically evaluate one of India's most prospective offshore basins
• Described as "a new chapter in India's journey towards energy security"; the programme uses world-class deepwater drilling technology to unlock new hydrocarbon resources and reduce import dependence
• Credited a decade of exploration & production reforms: Hydrocarbon Exploration and Licensing Policy (HELP); Open Acreage Licensing Programme (OALP) replacing the nomination-based approach; a transparent Revenue Sharing framework; and opening of nearly 99% of erstwhile offshore "No-Go" areas for exploration
• Nearly 81% of India's active exploration acreage has been awarded after 2014

🎯 UPSC Relevance: GS3 Economy/Energy — energy security, upstream oil & gas sector reforms, reducing import dependence and self-reliance.
