Compared with the S-wave micro-logging method, the P wave and S wave velocity ratio scanning method is more simple and practical, and has the advantages of simple operation and low cost...

... ABSTRACT It is critical to eliminate residual moveout of CMP gathers to get good seismic stacked profiles and pick AVO information correctly. This paper develops a new method of residual static correction based on matching pursuit algorithm. Taking advantage of matching pursuit algorithm...
