Abstract

Krishna Godavari Basin is a peri-cratonic passive margin basin on the east coast of India (Figure 1). The onland part consists of 28 000 km2 and is mostly alluvium covered. Krishna and Godavari are the two major river systems which drain the area and discharge in the Bay of Bengal. The offshore basinal area covers 24 000 km2 to the isobath of 200 m. However, the basin extends into deeper water and covers a much larger area. The basin's characteristic feature is its en-echelon horst and graben system which is filled with a thick pile of sediments of Permian-to-Recent age and emerging as one of India's most promising petroliferous areas. Commercial accumulation of hydrocarbons occurs in sediments from the Permian to as young as the Pliocene.
