1. A device adapted for storing instructions, said instructions adapted to be executed by a processor of a workstation, said workstation adapted to receive data including horizon data representing one or more horizons in an earth formation and fault data representing one or more faults intersecting at least some of said horizons, said instructions, when executed by said processor of said workstation, conducting a process comprising the steps of:

  • (a) computing a preliminary unfaulted horizon model using only said horizon data,(b) computing intersections between said preliminary unfaulted horizon model and each of the faults intersecting said horizon model, at least some of said intersections between said horizon model and said each of said faults being inconsistent intersections, and(c) filtering in the vicinity of said inconsistent intersections.
