Abstract

Delineating the pay sands for exploration/development in Cambay basin is generally interpretation of facies. Sands in Chatral unit I of Younger Cambay shale of Cambay basin are localized. Drilling exploratory/development locations on the basis of structural interpretation from surface seismic data have occasionally been successful in the study area. Utilizing leads from seismic forward modeling, the facies interpretation carried out through amplitudes studies validates at all the drilled well locations. Study seems to have resolved the issue of delineating the reservoir in Chatral I unit. Mapping through this method has brought out distribution of sands. Except two producing wells, all other wells around are placed outside the sand distribution map of the unit. No well is yet drilled in the area in the East of the producing wells, where mapping shows the presence of sand. The area is available for additional oil.
