India's Hydrocarbon Outlook – 2022-2023

64 DGH: 3 DECADES OF UNLOCKING INDIA'S HYDROCARBON POTENTIAL Kerala-Konkan (KK) is a Category III basin, and it has an area of 580,000 sq. km. with 90,380 sq. km. shallow water area and 489,620 sq. km. deepwater area. In the basin, 5 plays are present within Early Cretaceous-to- Miocene. Kerala-Konkan Basin is a potential petroliferous province, characterized by carbonate-siliciclastic shallow to deepwater sediments. The basin outline covers mainly the offshore provinces with isolated fringes of Miocene and younger sediments in coastal onland area. Situated on the south-west tip of India, Kerala-Konkan basin is flanked by two prominent North-South oriented oceanic fracture zones. The basin is a rifted passive margin basin that hosts sediments, ranging from Mesozoic to Recent. Situated on the south-west tip of India, Kerala-Konkan basin is flanked by two prominent North-South oriented oceanic fracture zones. Deepest play is the Early Cretaceous and shallowest are Oligo-Miocene. Petroleum system model could be constructed based on corroborative datasets of broad-grid seismic and wells. Prospectivity The Kerala-Konkan (KK) basin has a total hydrocarbon inplace of 605 MMTOE, which is entirely undiscovered and potential for intense exploration. The basin has been assessed earlier during 1995- 96 study along with 14 other basins. During 2017 Hydrocarbon Resource Assessment Study, 3D PSM approach has been used due to availability of adequate datasets. The 2017 resource reassessment study has incorporated 142,061 LKM of 2D seismic data, 13,529 SKM of 3D seismic data, 20 drilled well information. Seismic coverage is broad grid and well data are sparse. Gravity, 2D seismic data and reports are good while magnetic, geochemical, 3D seismic and 13. KERALA-KONKAN (KK) BASIN DGH Internal DGH Archive Resources are entirely undiscovered. Prospective area points to shelf area around Cochin Low. Half of total resources envisaged in Late Cretaceous play are below basalts.
