A new, fully integrated method for seismic geohazard prediction ahead of the bit while drilling

摘要

Geohazards create safety risks and increase drilling costs. Many are caused by uncertainties in the estimated formation pressures and the locations of geological structures. We introduced a new technique that decreases these uncertainties ahead of the bit during drilling. The method involves integration of surface seismic data, LWD or wireline well data, rock-physics information, logistics and planning, and fast turnaround times for "in-time" results.
