WIT Inc. has the capability to efficiently and effectively image 3D offset VSP data in "lookahead" mode, using our 3D Shot Gather Migration. VSP imaging can be thought of simply as imaging from a topographic datum, albeit one where the source and receiver planes are roughly orthogonal.

Once the rig has stopped to acquire the VSP, the timetable to process and interpret the VSP image is critically short. Thus, any time spent in preparation of VSP acquisition can reduce turnaround time and improve the results. Our 3D Acoustic Wavefield Simulation algorithm can perform waveform modeleling of a VSP prior to acquisition, helping processors to understand head waves and multiples that may lead to spurious interpretations when the real VSP is acquired.
