India's Hydrocarbon Outlook – 2022-2023

157 DGH: 3 DECADES OF UNLOCKING INDIA'S HYDROCARBON POTENTIAL 7.1.3 Status of the awarded CBM blocks The first commercial production from the CBM blocks commenced in the year 2007 from the Raniganj South block operated by M/s. Great Eastern Energy Corp. Ltd. (GEECL). Thereafter three (3) more CBM Blocks, Raniganj (East) Operated by M/s. Essar Oil & Gas Exploration & Production Ltd (EOGEPL), Sohagpur (West) operated by M/s. Reliance Industries ltd. (RIL) and Bokaro operated by M/s. Oil and Natural Gas Ltd. (ONGC) started its commercial production in 2016, 2017 & 2019 respectively. In addition to this incidental CBM gas is being produced during the testing of CBM wells in Jharia block operated by ONGC. At present, the active acreage for CBM exploration & production is around 6200 Sq km, having peak production potential of 18MMSCMD. Twelve (12) CBM Blocks are under operation currently of which 4 are in exploration, 3 in development and 5 are in production stage. The cumulative CBM production as of 31 st Dec 2022 is 5.6 BCM with average rate of 1.9 MMSCMD. 7.1.4 CBM Resources and Block Performances The Gondwana sediments of eastern India host the bulk of India’s coal reserves and all the current CBM-producing blocks. The majority of the best prospective areas for CBM development are found to be in eastern India, situated in the belt of Damodar-Koel valley and Son valley. CBM’s initial reserve & ultimate reserve has increased drastically since last 10 years. Taking 2008 as base year the initial reserve has increased approximately by 108% and ultimate reserve has increased approximately by 90%.
