India’s Hydrocarbon Outlook 2024 50 A Report on Exploration & Production Activities Petroleum system model results show prospective trend towards northeast part of offshore adjoining Bengal offshore. High resolution seismic acquisition for delineating deeper plays and supporting pore-pressure study in high pressure area are the key focus. In the basin, 10 plays exist within CretaceousTertiary. Petroleum system was modelled in 3D basis adequate datasets. Onland sub-basin has a total hydrocarbon in-place of 22 MMTOE and this is entirely undiscovered risked inplace. The basin has 100% of total inplace, potential to be explored and discovered. Offshore sub-basin has a total hydrocarbon inplace of 375 MMTOE. This includes discovered in-place of 77 MMTOE and undiscovered risked in-place of 298 MMTOE. The discovered in-place is subject to commercial development. The basin has 79.5% of total inplace, potential to be explored and discovered. 2 discoveries were notified during the year under OALP regime in Deepwater. Shale-coal couplet of Early Cretaceous-Late Jurassic in the syn rift grabens is the likely kitchen with TOC up-to 9.5%, followed by Miocene post-rift marine shales having TOC 0.99-6.81%.
