Improved Seismic Resolution through Fine Spatial Sampling - a 2D Example, Onshore Abu Dhabi

A-01 IMPROVED SEISMIC RESOLUTION THROUGH FINE SPATIAL SAMPLING - A 2D EXAMPLE ONSHORE ABU DHABI Abstract 1 During the late 1990's efforts were made by the Abu Dhabi Company for Onshore Operations (ADCO) in co-operation with WesternGeco to improve 3D seismic data quality by redistributing the source point energy over a finer spatial sampling of source points in the cross line direction. With the success of this approach and better understanding of the source-related issues consideration was given to optimization of the 3D receiver configuration. The receiver array pattern used for 3D surveys had been derived from earlier empirical 2D
