Seismic survey design, data acquisition and processing of complex Andean structures

Narrow offset seismic data has limitations in areas with structural complexity. Seismic acquisition cost makes prohibitive to acquire quality seismic data, therefore balancing acquisition cost and data quality is a challenge. Combining technologies such as recording Wide Offset seismic to be processed in the Shot-Receiver domains using Wave Equation Migration (WEM) algorithms is a rational approach. A reduced number of shots during acquisition results in lower operational costs. Forward WEM modeling is required during the survey design to estimate the correct shot decimation in the presence of noise, to avoid losing of structural information.
