PRACTICAL DEPTH CONVERSION WITH SPREADSHEET

Richard A. Box British Gas Houston In the oil and gas business, seismic time to depth conversion problems are best solved, in many cases, by looking for velocity versus depth relationships on a spreadsheet program with graphics capability. Thus seismic data may be married with well data in a sensible way with minimum computation. The work is done by the interpreter as part of the mapping step, not by data processing contractors, or anyone else unfamiliar with the geology. The incremental
