Feature Article in The Leading Edge

WIT authors have published an invited paper on land PSDM and RTM in the November, 2010 The Leading Edge, the SEG's flagship publication. In the words of the editors, "As you'll see, RTM has moved beyond the realm of the easy synthetic...What's more, you'll see that RTM is moving beyond the Gulf of Mexico and invading turf usually left for more mundane imaging methods such as time migration...Higginbotham et al. demonstrate that advanced PSDM workflows are not only applicable, but probably indispensible, for successful prospecting in many onshore basins...Their field data examples show that PSDM can significantly improve the resolution of faults and steep dips, even when the lateral velocity variation is not radical."

Depth imaging for land seismic?
One Houston-based company says, “Absolutely.”

Rhonda Duey, Senior Editor

There seems to be a trend these days to take technology developed for marine seismic acquisition and processing and apply it to land. Recent examples have included a company that uses land “streamers” towed behind a truck rather than a boat and the announcement from Shell and PGS that the two companies would develop a land version of PGS’ OptoSeis fiberoptic technology.

A small company called Wave Imaging Technology (WIT) hopes to accomplish a similar move to dry land in seismic processing, using depth imaging techniques commonly applied to subsalt plays onshore, particularly in shale plays. With revenues tripling this year, it might not be a small company much longer.

RTM webcast posted

Press "play" below for a "tutorial" on our reverse-time migration (RTM). This video is narrated by WIT's CEO, Morgan Brown, and is excerpted from a talk given by Dr. Brown at the June, 2010 Denver Geophysical Society luncheon. It puts RTM into the context of other prestack depth migration methods, describes the algorithm in a step-by-step fashion, and illustrates RTM with two field data examples (Gulf Coast salt dome and Wyoming anticline).

Second WIT Patent Application published

WIT's second US Patent application, "Estimation of Propagation Angles in Geology with Application to Determination of Propagation Velocity and Angle-Domain Imaging", has been published by the USPTO on May 6, 2010. This patent application protects the innovations behind WIT Angle. Please download the patent application from our website.

New RTM, US Patent Application published

WIT has rolled its new Reverse-Time Migration (RTM) into production. This advanced wave equation imaging algorithm can image "overturned" events and steep faults that one-way WEM algorithms have difficulty imaging. Above: See a comparison of PSTM and our new RTM on the classic Spindletop salt dome.

WIT's 2008 patent application for Migration Velocity Focusing Analysis (MVFA) has been published by the USPTO.
