India’s Hydrocarbon Outlook 2024 94 A Report on Exploration & Production Activities 15. KAREWA BASIN Karewa 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 Jammu and Kashmir. Source: DGH Internal Source: DGH Internal Karewa is an intermontane basin, located in Kashmir valley of northwestern Himalayas. It is an oval-shaped basin between Pir-Panjal Range in the southwest and Zanskar Range to its northeast. The elements of petroleum system in the basin are largely speculative. The basin has the close analogy with Potwar Basin of Pakistan. The identified three plays viz. Paleozoic Play, Triassic Limestone Play and PlioPleistocene Play has six assessment units each. The Mesozoic shales and carbonates are considered to have optimal TOC in the range of 2.12-2.82% to act as source for the Devonian, Carboniferous, and Pliocene sediments. In the basin, 3 plays are present within Paleozoic, Mesozoic and Plio-Pleistocene. Aerial Yield approach is used on analogy of Kohat Potwar Basin (Pakistan). 14,000m sedimentary thickness has been envisaged in the basin. Karewa basin has a total hydrocarbon in-place of 6 MMTOE and this is entirely undiscovered risked in- place. Hydrocarbon prospectivity and Basin maturity:
