Maximizing Information Content of Seismic Data through Optimized Acquisition Design - A Case History from South Tunisia

The objective of this Land seismic case study is to share the learnings ENI and CGG gained from a field test performed in the course of a production project located in South Tunisia. The objective of this study was to evaluate how to optimally use the available field equipment to Maximize the information content of the seismic data for the purpose of enhanced structural and quantitative interpretation. The use of single vibrators, of smaller receiver arrays and reduced slip time, did allow, using the same equipment, to efficiently acquire the seismic data with a trace density significantly higher than conventional coverage. Final Imaging results illustrate that Trace density and not source strength, is the key parameter that controls the qualitative and quantitative seismic Imaging value of the Subsurface
