India’s Hydrocarbon Outlook 2024 36 A Report on Exploration & Production Activities 1. KRISHNA-GODAVARI (KG) BASIN Krishna-Godavari (KG) is a Category I basin, implying that the basin has significant commercial discovered inplace, potential to be produced at an optimum level. Source: DGH Internal Source: DGH Internal Krishna-Godavari (KG) is located along the east coast of Indian peninsula, lying between Mahanadi basin in the north and Cauvery basin towards south. The basin is most prospective and largely proven with maximum resources (38% of total offshore), and is known for country’s largest deepwater gas field. Both deepwater and shallow water are extensively appraised with large-scale datasets, which is an opportunity for intensive exploration of stratigraphic traps, majorly the channelized deposits. Commercial hydrocarbon occurrences spread over a wide stratigraphic horizons ranging from Permian to Pliocene with geographical distribution over onland, offshore including ultradeep bathymetry. Several oil and gas fields have been discovered, both onland and offshore. The KG basin consists of sediments with thickness of more than 7,000m, ranging in age from the Early Permian to Recent. The basin’s onland part is mostly covered by the alluviums deposited by the two major river systems, viz., Godavari and Krishna and several stratigraphic sequences including Lower Gondwanas that are outcropped near the basin margin. The reservoirs are primarily sandstones with isolated occurrences of limestone and unconventional reservoirs like fractured basalts. Effective source rocks are identified to be the shales of Permian to Eocene. Biogenic reservoirs and gas hydrate deposits have been established in the basin. The geographical area of the basin partially overlaps with the state of Andhra Pradesh.
