The processing of 7504.05 line km of offshore 2D Seismic data, acquired in CORAL SEA, N.E. Australia acquired during 1973-74 by Geophysical Service International for Shell Development (Australia) PTY. LTD. under the survey name Shell Scientific Marine Seismic. Speculative Processing was done by Samit Spectrum EIT Pvt. Ltd in 2019. Processing was carried out using state of art processing software SeisSpace/ProMAX running on Linux Cluster. Quality control procedures and interactive evaluation was done at every step of processing to obtain the final outputs at acceptable international standards. The data processing was independently Quality Controlled . Parameter testing was done at every stage of processing to finalize the optimum parameters for Pre Stack Time Migration (PreSTM) Processing.
All 42 lines totaling 7504.05 LKM were processed for Pre Stack Time Migration. Details of lines (SP Range, CDP Range, LKM) are given in the processing report.
