Abstract


Rift-fill play of Early Cretaceous age have emerged out to be most important exploration targets in the Krishna -Godavari basin in particular offshore area, as a number of similar play has been established. Recently, commercial oil bearing reservoirs of multi-stacked channel sands were encountered in well-C from Nandigama-Arenaceous unit equivalent to rift-fill sequence. This has necessitated studies to delineate the reservoir. An inversion study has been undertaken with an objective of delineating the reservoir

Keywords
