Maximizing information content of seismic data through optimized acquisition design. A case history from South Tunisia

Numerous evaluations, conducted on various sites, converge towards a shared conclusion: the geophysical value of an acquisition is primarily driven by the density of traces acquired in the field. To confirm this principle also applies in North Africa, ENI and CGG agreed on a technical collaboration. The objective of the collaboration was to demonstrate, on a crew operating in South of Tunisia, that, without additional equipment, using modern high productivity schemes it was possible to efficiently increase the conventional Trace Density by a factor of 10 to 50 with a significant increase in geophysical value all along the processing, imaging and interpretation steps.
