Method of designing geophysical surveys

摘要

A method for the design of VSP surveys for the purpose of imaging a reef in the formations surrounding the well in question. The basic steps include: building a geophysical model; defining receiver locations in the well within the model; defining the target (reef); ray tracing from receivers to surface via target; defining source locations on surface based on ray density pattern; and validate by ray tracing from source locations to receiver locations via target.
