India’s Hydrocarbon Outlook 2024 33 A Report on Exploration & Production Activities With 26 sedimentary basins mapped and assessed, India has discovered petroleum of 12.0 billion ton oil equivalent and undiscovered potential of 12.9 billion ton oil equivalent, which is duly weighed with geologic risks. While this is an estimate of conventional petroleum occurrence, unconventional petroleum exists in form of coal seam gas, shale plays, tight plays, basement fractures and gas hydrate. Sedimentary basins are divided into three categoriesmapping conventional resources and following the rationale of Petroleum Resources Management System (PRMS), a global standard for reporting petroleum resources and reserves based on techno-commercial merits.
