Open the CIPO recordAbstract From the Canadian patent
A computer implemented apparatus and method (Fig 3) for discovering hydrocarbon bearing formations yields a direct indication of hydrocarbon resulting from analyzing seismic amplitude data. The method uses an algorithm for determining a seismic attribute dip (DAD) (28) in which each sample point of each seismic trace in a survey is analyzed to determine a planar dip associated with the reflection point (20) and a normalized delta amplitude in , the direction of dip. Displaying the DAD values in time slice or horizon slice (21) provides a direct indicator of hydrocarbons. The inventive method automatically analyzes each digitized data point in the survey by crosscorrelating the traces …

Why it's free to use
- Filed November 1, 1999. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended November 1, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 1, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
