Abstract

3D seismic data of three volumes pertaining to Jotana area of Cambay basin was acquired in two phases using scorpion I/O-IV recording system. This data was taken for reprocessing to improve imaging at Mehsana, Mandhali and Linch equivalent levels. These sands in Mehsana block of North Cambay Basin are known for multiple hydrocarbons bearing sand reservoir within Younger and Older Cambay Shale. The limitations for the area are complex weathering and sub weathering media resulting into low signal-to-noise ratio and low frequency content in the recorded data. The data also contained high frequency noise burst and ground roll. All the due care was taken during the processing of the data .The final processed output shows a marked improvement at all the levels
