Claim One:
1. A method of modeling a reservoir ( 115 ) having a horizon surface with a reverse fault ( 220 ), the method comprising: a) partitioning a volume ( 135 ) of the reservoir ( 115 ) into fault blocks ( 615, 625 and 635 ), wherein a bounding surface ( 645, 655 ) of each of the fault blocks ( 615, 625 and 635 ) includes a portion of the reverse fault, wherein an interior of each of the fault blocks ( 615, 625 and 635 ) includes only single valued horizon surfaces; b) partitioning horizon data describing the reservoir ( 115 ) into data sets, the data sets defining patches ( 710 and 720 ), wherein each patch corresponds to a fault block, wherein the patches ( 710 and 720 ) include an up-thrown ( 475 ) and down-thrown ( 485 ) fault trace on opposing sides of the reverse fault ( 220 ); and c) developing continuity constraints ( 905 ) along artificially extended fault block boundaries ( 680 ), wherein the continuity constraints ( 905 ) match endpoints ( 610 and 620 ) of the up-thrown ( 475 ) and down-thrown ( 485 ) fault trace.
