Walkaway-VSP data has a uniquely superior at extracting geophysical parameters. Applying the extracted parameters to surface seismic data processing can make the processing procedure quantifiable and greatly enhance image fidelity, resolution and precision. Based on the need to improve the characterization of a fractured vuggy carbonate reservoir in the studied oilfield of western China, we extracted geophysical parameters like velocity, true amplitude recovery (TAR) factor, Q factor and anisotropy estimated from zero offset VSP and Walkaway-VSP data, and applied them to high density surface seismic data processing. The result shows that the resolution and precision of imaged surface seismic data have been improved significantly; moreover, the accuracy of geobody characterization has been enhanced. Our study indicates a promising application of the VSP technique in this field.
