India’s Hydrocarbon Outlook 2024 86 A Report on Exploration & Production Activities 11. NARMADA BASIN Narmada is a Category III basin, implying that the basin has entirely undiscovered inplace, that calls for intense exploration for a potential discovery. The geographical area of the basin partially overlaps with the state(s) of Dadra and Nagar Haveli, Daman and Diu, Gujarat, Madhya Pradesh, Maharashtra and Telangana. Source: DGH Internal Source: DGH Internal The basin is located in the northwestern part of Indian Peninsula and it extends up to the eastern limit of Cambay Basin while eastward it merges with the western boundary of Satpura. The elements of petroleum system in the basin are largely speculative. Based on Gravity and DSS data, sedimentary thickness of the basin is envisaged to be in the range of 300 m to 2.0 kms. The basin has the close analogy with Cooper Basin of Australia. The basin has Pre-Trappean Gondwana play, which is divided into four assessment units based on available geological rationales. Basin is largely covered by Decan trap basalts. Sub-trappean sediments are the focus area of exploration. The hydrocarbon potential of Narmada Basin is envisaged mainly based on MT and DSS data in absence of conventional seismic and deep drilling information. Based on analogy of Satpura Basin, The Gondwana shale and limestone are expected source rocks. Reservoir rocks are envisaged to be Nimar sandstone and Bagh limestone along with Gondwana sediments. In the basin, 1 play is identified within sub-trappean Gondwana. 400-1,500m of sedimentary thickness was envisaged in the basin. Aerial Yield method was used on analogy of Cooper Basin, Australia. Narmada basin has a total hydrocarbon in-place of 9 MMTOE and this is entirely undiscovered risked in- place. Hydrocarbon prospectivity and Basin maturity:
