Linking Shelf Delta to Deep Water; Krishna-Godavari Basin

Krishna-Godavari basin located on the east coast of India represents a complete depositional setting with well defined shelf to shelf edge delta to deep water. This basin has a lateral stretch of about 500 km and extends more than 200 km from the coast into the deep sea. This basin has been fed dominantly by Krishna and Godavari river systems along with numerous tributaries. The area is adequately covered by several vintages of 2D and focused 3D seismic data which has been primarily used for subsurface imaging. Further the depositional units have been identified by interpreting seismic stratal pattern and the facies distribution in a sequence stratigraphic framework. This is supplemented by information from wireline logs and cores. The gradational facies pattern, sequence boundary, transgressive surface, maximum flooding surface, channel architecture etc. have been demonstrated in selected seismic sections far developing the concept. Linking the depositional elements from shelf to deep water in a sequence stratigraphic framework for this basin is a good guide for hydrocarbon exploration.
