India’s Hydrocarbon Outlook 2024 64 A Report on Exploration & Production Activities In the basin, 8 plays are identified within Basement and Tertiary. Petroleum system was modelled in 3D basis adequate datasets. Assam Shelf basin has a total hydrocarbon inplace of 2,700 MMTOE. This includes discovered in-place of 1,826 MMTOE and undiscovered risked in-place of 874 MMTOE. The discovered in-place is under commercial production. The basin has 32.4% of total inplace, potential to be explored and discovered. 2 field development plans were reviewed during the year under Pre-NELP(1) and DSF(1) regime in Onland. Commercial production, post India’s independence commenced in 1965. Major producing fields with cumulative production in parenthesis are namely Rudrasagar (11 MMT, 3 BCM), Borholla (3 MMT), Greater Naharkatiya (56 MMT, 33 BCM), Greater Moran (19 MMT, 6.5 BCM) Greater Jorajan (16 MMT, 19 BCM)Greater Hydrocarbon prospectivity and Basin maturity: Discoveries and Development: Overview of producing fields: Basin datasets, studies and opportunities: Hapjan (25 MMT, 8 BCM), Greater Chandmari (70 MMT, 8.5 BCM) Geleki & North Geleki (19 MMT, 6.7 BCM). The sub-basin has 47 fields with 1,404 wells. The maximum flow rates achieved by any field on record in 2023-24 are, Oil 20,400 BOPD and Gas 4 MMSCMD. As of 31.03.2024, NDR has archived data of 62,493 LKM 2D seismic, 40,830 SKM 3D seismic and 3,097 wells. Under various campaigns by GoI, geophysical data were acquired in onland area. Under National Seismic Programme (NSP), 3,160 LKM 2D seismic data were acquired. Wadia Institute of Himalayan Geology, Dehradun, India carried out tectonic anomaly study using AI/ML technique in Amguri field and adjoining areas. Source: DGH Internal Source: DGH Internal
