A Beam Steering Process for Seismic Data
A computer program has been developed on the Cyber 205 supercomputer at the University of Calgary that performs a beam steering process on physical model seismic reflection data. The routine is applied during the synthesis of receiver array configurations used to compress raw shot records from the modeling system. Spatial and velocity filtering methods for the suppression of random and coherent noise are applied during the process. The computationally intensive approach used is facilitated by the high speed of the vector computer, generating each beam steered output trace in less than one second.
