India's Hydrocarbon Outlook – 2022-2023

73 DGH: 3 DECADES OF UNLOCKING INDIA'S HYDROCARBON POTENTIAL The basin has been assessed for the first time. During 2017 Hydrocarbon Resource Assessment Study, Aerial Yield has been used on analogy of KG Basin. The study has incorporated geological map, GM data, and geochemical data (source rock samples). The 2017 resource reassessment study has incorporated750LKMof 2Dseismicdata, 2drilled well information. Gravity data and report are of good quality while Magnetic and Geochemical data are fair and 2D Seismic and Wells data are poor with 3D Seismic. The data reliability is good. Mandapeta area of the KG Basin. has been used as analogue. Inadequate geoscientific data leads to adopt areal yield method to assess the hydrocarbon resources. Less seismic data is available. Maturity of sediments is primary focus. Results may be reviewed as and when new sets of data are available. The play-level undiscovered (risked) hydrocarbon inplace for Pranhita-Godavari (PG) basin is given below: The basin is spread into the state(s) of Andhra Pradesh, Chhattisgarh, Madhya Pradesh, Maharashtra, Telangana. 4 MMTOE 44 MMTOE Paleozoic Permo-Triassic (Upper Kamthi): Paleozoic Permian: Paleozoic Permo-Triassic (Middle Kamthi): Paleozoic Carboniferous (Upper Permian): 43 MMTOE 3 MMTOE Status, available datasets and opportunities Under National Seismic Programme, conducted during 2016-22 in unappraised onland areas, 735 LKM broad-band 2D seismic data were acquired in the basin. As of March 1, 2023, NDR, for Pranhita- Godavari (PG) basin has archived 1,903 LKM of 2D seismic data, 4 drilled well information. In PG basin, 5 CBM blocks with cumulative acreage of 1,063 sq km are on offer under Special CBM Bid Round 2022. The blocks are spread in Telengana(3) and Maharashtra(2). 0 40 80 120 160 20 KM PRANHITA-GODAVARI BASIN MAHARASHTRA CHHATTISGARH TELANGANA ANDHRA PRADESH ODISHA MADHYA PRADESH LEGEND 2D SEISMIC WELLS PRANHITA-GODAVARI BASIN SEDIMENTARY BASIN DGH Internal
