India’s Hydrocarbon Outlook 2024 45 A Report on Exploration & Production Activities Source: DGH Internal Source: DGH Internal In the basin, 16 plays are located within Middle Jurassic-to-Early Cretaceous in Onland and Middle Jurassic-to-Trap-to-Middle Miocene in Offshore. Petroleum systemwas modelled in 3D where datasets were adequate and Aerial Yield method was used where data were limited. Onland sub-basin has a total hydrocarbon in-place of 33 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 267 MMTOE. This includes discovered in-place of 70 MMTOE and undiscovered risked in-place of 197 MMTOE. The discovered in-place is subject to commercial development. The basin has 73.8% of total inplace, potential to be explored and discovered. Sub-basalt imaging, variable basalt thickness and sub-optimal onland seismic data are some areas of focus for exploring Cretaceous plays. Late Jurassic and Early Cretaceous shale with Discoveries and Development: 1 field development plan was reviewed during the year under NELP regime in Shallow water. As of 31.03.2024, NDR has archived data of 196,462 LKM 2D seismic, 29,624 SKM 3D seismic and 38 wells. Under various campaigns by GoI, geophysical data were acquired, initially in onland basins and later, extended to offshore areas. Under National Seismic Programme (NSP), 2,306 LKM 2D seismic data were acquired. In another initiative, titled Mission Anveshan 660 LKM 2D seismic are planned as an in-fill data acquisition campaign of NSP. The offshore was part of 46,453 LKMWest Coast EEZ 2D seismic survey. The basin has been identified for drilling of one stratigraphic well under the GoI-approved plan. TOC- 0.80% is expected to be the main source rock for clastic and carbonate reservoirs. Low frequency 2D seismic API could add to improved sub-trappean imaging. Hydrocarbon prospectivity and Basin maturity: Basin datasets, studies and opportunities: Pandit Deendayal Energy University(PDEU), Gandhinagar, India has carried out geoscientific data analysis as a part of basin-scale research study.
