According to the Energy Statistics India 2025 report, which of the following states holds the second-largest share of crude oil reserves in India as on April 1, 2024?

The correct answer is Assam . Key Points The Energy Statistics India 2025 report, published by the Ministry of Statistics and Programme Implementation (MoSPI) , outlines the status of hydrocarbon reserves in the country as of April 1, 2024 . The total estimated reserves of Crude Oil in India are recorded at approximately 597.58 Million Tonnes (MT) . The Western Offshore region remains the largest contributor to India's total crude oil reserves, holding a share of 32.57% (194.58 MT). Among the states, Rajasthan possesses the largest share of crude oil reserves, accounting for 24.30% (145.24 MT) of the national total. Assam holds the second-largest share among the states, with estimated reserves of 133.51 MT , representing 22.34% of India's total reserves. The state of Gujarat follows in the third position among states, with a share of 11.96% (71.49 MT). Additional Information Assam's Petroleum Legacy : Assam is the pioneer of the Indian petroleum industry, with the Digboi Oil Refinery , commissioned in 1901 , being the oldest operating refinery in Asia . The state features prominent oil fields such as Naharkatiya , Moran-Hugrijan , and Rudrasagar , which are primarily managed by Oil India Limited (OIL) and ONGC . Other States : Nagaland : It holds a relatively small portion of reserves (approx 2.38 MT ) located within the Assam-Arakan Basin . Tripura : While rich in Natural Gas , its crude oil reserves are not as significant as those in the Brahmaputra valley. West Bengal : Exploration in the Bengal Basin has shifted focus toward Coal Bed Methane (CBM) and shale gas due to the lack of substantial crude oil deposits. Institutional Framework : The Directorate General of Hydrocarbons (DGH) under the Ministry of Petroleum and Natural Gas oversees the management of these resources to ensure energy security .
