Identification and mapping of carbonate bank in eastern part of Surat depression, Bombay Offshore Basin and its hydrocarbon prospects. Banerjee et al. Indian J. Petrol. Geology, December 1996, 5(2), 37--46.
A carbonate bank has been identified and mapped in clastic dominated eastern homoclinal part of Surat depression. Post rift tectonic activity, indicated by the presence of horst blocks at Early Eocene level, caused relative shallowing up of the depositional floor. This coupled with the absence of clastic influx led to the carbonate sedimentation in the area due to shoaling over horst block. Primary porosity pods are the main targets for hydrocarbon exploration. 10 refs.
