| 6018497 | Method and apparatus for generating more accurate earth formation grid cell property information for use by a simulator to display more accurate simulation results of the formation near a wellbore A Petragrid method and apparatus generates grid cell property information that is adapted for use by a computer simulation apparatus which simulates properties of an earth formation located near one or more wellbores. An interpretation workstation include... | 01/25/2000 |
| 6014343 | Automatic non-artificially extended fault surface based horizon modeling system An automatic, non-artificially extended, fault surface based horizon modeling method and apparatus produces a final faulted horizon model which is a three dimensional representation of a faulted earth formation including all the horizons and all the fault... | 01/11/2000 |
| 5999885 | Method and apparatus for automatically identifying fault cuts in seismic data using a horizon time structure An interpretation workstation based apparatus having an "Auto Fault" software stored therein automatically identifies a plurality of fault cuts in each of a plurality of horizons in a seismic data volume in response to a plurality of predetermined "horizo... | 12/07/1999 |
| 5995907 | Seismic signal processing method and apparatus for generating time slice or horizon maps in response to seismic traces and quadrature traces to determine geologic features A method and associated apparatus for generating time slice maps and/or horizon maps, representative of a time slice or a horizon in an earth formation that is subject to a seismic operation, in response to received seismic data includes the steps of: (a)... | 11/30/1999 |
| 5982707 | Method and apparatus for determining geologic relationships for intersecting faults A novel fault framework method and apparatus automatically computes the relationships between intersecting fault surfaces. When faults are loaded into the novel fault framework apparatus, all intersecting fault pairs are determined and the fault fault int... | 11/09/1999 |
