Open the CIPO recordAbstract From the Canadian patent
The invention relates to a method of processing seismic data (102 104) on , parallel processors (106, 108 110), preferably on a massively parallel processor (MPP) (100). The input to the process is seismic data from one or more of a number of seismic lines (2). The end product of the invention is a DMO corrected, zero-offset seismic image of the subsurface. By repeating the method on different input offsets, the variation in reflection strength of a reflector as a function of the angle of incidence can be examined. The method includes a two stage parallelization. First a parallelization over the , incoming traces generates a suite of DMO-corrected partial images for each point on …

Why it's free to use
- Filed October 2, 1996 and granted February 5, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended October 2, 2016.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 2, 2018.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
