Combining CRS Technology and Sparse 3D Seismic Surveys – A New Approach to Acquisition Design

P182 Z-99 Combining CRS technology and sparse 3D seismic surveys – a new approach to acquisition design Introduction 1 Seismic acquisition in frontier areas faces a high risk when dealing with remote areas with difficult access limited operation times due to seasonal influences and governmental restrictions and a large uncertainty in the design of optimum acquisition parameters. Under such circumstances high-fold 3D seismic surveying is not feasable but 2D surveying may also not be appropriate to describe the areal extent of potential targets. Sparse 3D surveys are frequently used as a compromise. A land data example from North Africa is
