Interpreters are always seeking improvements to seismic data in quality, resolution, and the accuracy with which the data represent the underlying geology. Consistency of the seismic image with known control points, usually wells, is essential. The bridge between the high-resolution, geographically sparse, depth-indexed world of logs and the low-resolution, geographically ubiquitous and time-indexed world of seismic is the vertical seismic profile (VSP) in its various geometries.
