India’s Hydrocarbon Outlook 2024 79 A Report on Exploration & Production Activities 8. SATPURA-SOUTH REWA-DAMODAR BASIN Satpura-South Rewa-Damodar is a Category III basin, implying that the basin has entirely undiscovered inplace, that calls for intense exploration for a potential discovery. The basin, however is commercially producing unconventional resource like coal bedmethane. Satpura sub-basin partially overlaps with the state of Madhya Pradesh. South Rewa sub-basin partially overlaps with the state(s) of Chhattisgarh, Madhya Pradesh, Odisha and Uttar Pradesh. Damodar sub-basin partially overlaps with the state(s) of Jharkhand and West Bengal. Source: DGH Internal Source: DGH Internal The Gondwana rocks of Satpura-South RewaDamodar Basin are exposed along a linear belt in Indian peninsular region. The basin has limited geoscientific data, specific to exploration of conventional hydrocarbons. The elements of conventional petroleum system in the basin are largely speculative. The basin has Gondwana sediments - both Lower Permian plays and the Upper Mesozoic. The basin has the close analogy with Cooper Basin of Australia. The study envisages the hypothetical Gondwana petroleum system, which, based on geological rationales is considered to be a close analogue with the Cooper Basin of Australia. There are three plays identified. viz. Early Permian, Mid. to Late Permian and Triassic to Cretaceous across all three sub-basins viz. Satpura, South Rewa and Damodar. Instances of igneous intrusions call for an integrated approach during mapping hydrocarbon resources. Source rock is Barakar and Bijori/ Raniganj Formation of Permian period with TOC 2.44 to 6.4%. Out of the three basins, average organic content in Damodar basin is highest (6.06-6.4 % from Raniganj and Barren Measures) with Type III organic matter with sandstone reservoirs of Permian to Triassic (Barakar/Raniganj/Panchet).
