India’s Hydrocarbon Outlook 2024 127 A Report on Exploration & Production Activities Andaman Seismic Survey: Upon completion of seismic survey of onland basin areas under NSP, similar programme was planned in unappraised offshore area of Andaman Basin. The basin with 6,64,080 sq. km of India’s Exclusive Economic Zone (EEZ) was hitherto appraised to the extent of 36% with 71,290 LKM of 2D seismic, 13,710 sq. km of 3D seismic data and 22 exploratory wells, mostly drilled in the easterly located forearc areas of the basin. The basin area surrounding the Andaman & Nicobar (A&N) islands had established the presence of hydrocarbons; however, exploration activities were then restricted as most of the area (~370,000 sq km) was designated as “NoGo” Zone. Pursuant to inter-ministerial deliberations through Empowered Coordination Committee (ECC), DGH and the Department of Space (DoS) in coordination with the Island Development Authority (IDA) formulated a plan to carry out 22,500 LKM 2D seismic survey in unappraised areas of A National Seismic Program (NSP): Launched in October 2016, Government of India conducted 2D seismic survey in unappraised onland areas of Indian sedimentary basins. Under the programme, acquisition, processing, and interpretation (API) of 48,243 Line Kilo Metre (LKM) of 2D seismic survey was proposed. A total of 46,960 LKM (97% of the target) of 2D seismic data were acquired, processed and interpreted. The data acquisition programme was completed in February 2022. The processed seismic data along with reports were kept at National Data Repository (NDR). Gujarat Energy Research and Management Institute (GERMI), Gandhinagar , India conducted technical assurance study of the NSP data as the third party and such report was made available at NDR. DATA FOR COMPLETE APPRAISAL OF SEDIMENTARY BASINS ndaman Basin as a part of data acquisition campaign for hydrocarbon exploration. Started in August 2021, acquisition of 22,564 LKM broadband seismic data in ultra-deepwater at a water depth 1,500-3,000m was completed in February 2022. Post processing and interpretation, data along with reports were made available at NDR in October 2022.
