HOUSTON –TGS-NOPEC Geophysical Co. has added its reverse time migration algorithm to its commercial product list for the first time.
With this addition, TGS proprietary depth migration tool box includes two-way and one-way wave equation, and Kirchoff and beam algorithms complemented with velocity modeling which covers WEM scan, full-azimuth tomography, and anisotropic parameter estimation.
"The TGS RTM implementation combines the best attributes of one-way wave equation migration's ability to image events under salt and Kirchoff migration that can image steeply dipping and even overturned events" said Zhiming Li, vice president of Imaging Services for TGS.
