Application of a full 3D designature solution to a wide-azimuth survey

Abstract

The current drive within the industry is towards a "Full Bandwidth" solution for seismic imaging coupled with acquisition solutions such as "Multi-Azimuth", "Wide-Azimuth" and "Full-Azimuth". Additionally, changes in source array geometry and multi-sensor receivers have also been employed. The proper processing of these types of data requires that special attention is given to how the wave field is produced, its propagation through the earth and finally how it is being captured. Of particular interest, and in order of their relative impact to the wave field, are:  Surface ghost effects  Source array effects  Receiver array effects  Earth effects This paper will focus on the ghost and source array effects and the results achieved when they are handled properly.
