India's Hydrocarbon Outlook – 2022-2023

34 DGH: 3 DECADES OF UNLOCKING INDIA'S HYDROCARBON POTENTIAL India has a sedimentary basin cover of 3.4 million sq km and is appraised through geoscientific surveys to the extent of 61% of total area. However, the exploration through drilling has penetrated to less than 10% of the area. The country is favourably located with thick sedimentary rocks, in suitable geological settings of Rift, Fold-belt and Foreland regions. It belongs to Region 8 (South Asia) and is part of 171 Hydrocarbon Provinces mapped by USGS in 2012. There are 26 sedimentary basins mapped using latest GIS tools and categorized into three, based on conventional hydrocarbon resources, following the rationale of Petroleum Resources Management System (PRMS), a global standard for accounting of petroleum resources and reserves based on techno-commercial merits. There are 9 offshore basins, which account for 51% of total basin area. Based on conventional resource potential, 7 basins, which are commercially producing, are grouped under Category-I covering 30% of total basinal area (1.0 million sq km) and a total hydrocarbon of 21,487 MMTOE, which is 86% of country's total that includes discovered as well as risked undiscovered potential. These 7 basins are namely Krishna-Godavari (KG), Unlocking Hydrocarbon Potential of India’s Sedimentary Basins 2 34
