Abstract:

The Krishna-Godavari (KG) Basin is located in the central part of the eastern continental margin of India. The KG Basin contains a thick sequence of sediments with several cycles of deposition ranging in age from Late Carboniferous to Holocene. It is a major delta with 5-7 kilometers thick, argillaceous facies that has prograded seaward since the late Cretaceous and is a hydrocarbon exploration target. It has proven as Category I type basin i.e. proven petroliferous basin having potential reservoirs ranging in age from Permian to Ploiocene. In this paper the structural and stratigraphic mapping within the KG Basin is being carried out using some geophysical methods. Primarily seismic method is used for the exploration of oil and gas in KG Basin. The main objective of the study is to get the general geological setup of the area and to correlate it with some seismic sections and key refector with the log data.

Keywords: geophysical methods, structural setup, petroliferous, hydrocarbon exploration.
