Vedanta Oil and Gas, India's largest private-sector exploration and production firm, already contributes about a quarter of domestic crude. Management targets lifting that to 50% of India's domestic crude output.
NCLT sanctioned the split on December 16, 2025. It became effective May 1, 2026, and VOGL shares listed on BSE and NSE on June 15, 2026. Shareholders received one share in each of four new entities.
Parent Vedanta carried gross debt above ₹73,800 crore and net debt near ₹57,358 crore before the split. Estimates indicate VOGL assumed only 6–10% of parent standalone net debt, roughly $1.0–1.2 billion, preserving headroom for costly recovery projects.
Working interest sales volume dropped from 82.5 kboepd to 67.3 kboepd in FY25, a negative EBITDA impact of ₹1,130 crore. Gross operated production fell 19% year-over-year, and Q1 FY26 slipped further to 77.7 kboepd.
Mangala runs the world's largest full-field polymer flood, adding about 100 million stock tank barrels. An ASP pilot lifted oil cut from 8% to 70–80% within 3–4 weeks, targeting a 60% ultimate recovery factor versus 40% for polymer alone.
VOGL operates 39 OALP blocks and five discovered small field blocks. The Jaya discovery in Gujarat's Cambay Basin became the first field development plan submitted under OALP, lifting Cambay output 21% quarter-on-quarter.
Viceroy Research estimates VOGL spent about ₹4,230 crore on exploration since FY21, below the annual $200–300 million needed to replace Rajasthan declines. 2P reserves fell from 569 mmboe in FY22 to 399 mmboe in FY25.
Delhi High Court enforced Ravva arbitration awards worth up to $454 million in July 2026. Separately, a bench upheld denial of a 10-year CB/OS-2 extension, citing the Public Trust Doctrine and allowing ONGC to take over operations.
VOGL targets net-zero carbon operations by 2050 and is solarizing the 705-km Mangala pipeline across 36 installations. Protests in Tamil Nadu's Cauvery delta show how local opposition can block onshore exploration.
Post-demerger, Vedanta Oil and Gas must scale ASP flooding, prove OALP discoveries like Jaya, and manage legal risk. Read the full deep dive for the detailed financial, reservoir, and regulatory evidence behind that ambition.
