Methods of processing seismic data to remove unwanted noise from meaningful reflection signals are provided for. The seismic data is transformed from , the offset-time domain to the time-slowness domain using a Radon transformation. , Preferably, the Radon transformation is applied within defined slowness limits P min , and P max, where P min is a predetermined minimum slowness and P max is a predetermined maximum slowness, and an offset weighting factor x n is applied to the , amplitude data, wherein 0 < n < 1. A high resolution Radon transformation preferably is used, where the transformation is performed according to an index j of , the slowness set and a sampling variable …

Why it's free to use
- Filed August 28, 2003 and granted October 30, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended August 28, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 28, 2025.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
