Abstract

Abnormal pressured rocks are typical of many sedimentary basins world wide. Prediction of over / high pressures in the sedimentary sequences in any sedimentary basin is indeed a challenging problem. In Krishna Godavari Basin, over / high pressures occur in the subsurface from 1500m downwards and in thick sections of fine-grained sediments. Over / high pressures in a formation is a concern during all phases of Oil/Gas field operations viz., drilling, logging, testing, stimulation, completion and reservoir evaluation.
