Open the CIPO recordAbstract From the Canadian patent
Methods are provided for processing seismic data acquired during marine seismic operations when the seismic streamer cables or sources deviate from their desired acquisition track. The method initially processes the data using conventional normal moveout techniques, then applies conventional dip moveout techniques, followed by regularization of the cross-line data, and then 3-D migrating the regularized data. Regularization involves determining the signals at preselected cross-line positions based upon the signals detected and recorded at the measured cross-line CMP positions.

Why it's free to use
- Filed October 30, 1989. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended October 30, 2009.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 30, 2011.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
