Open the CIPO recordAbstract From the Canadian patent
A technique is provided for controlling the quality of processed seismic data without requiring subjective intervention. Seismic data for instance acquired , by land or marine techniques are supplied as input (1) and a portion for testing is selected (2). First and second combinations of seismic data processing steps are selected (3 and 6). The selected data portion is processed (4 and 7) using these combinations and the thus-processed portions are analyzed to calculate the attributes thereof (5 and 8). These measures are compared (9) and the combination of processing steps giving the better attributes is then used to process the input seismic data (10 or 11).

Why it's free to use
- Filed August 12, 1996 and granted March 20, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended August 12, 2016.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 12, 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.
