Claim 0:
1. A geologic modeling method for extracting hydrocarbons, the method comprising:
obtaining first and second physical space geologic models representing subsurface regions in physical space, the first and second physical space geologic models having different structural interpretations of one or more features;
mapping each of the first and second physical space geologic models to associated first and second design space models each representing an unfaulted subsurface region, said mapping employing associated first and second physical-to-design space mappings;
determining a design-to-design space mapping between the first design space model and the second design space model;
gridding the first design space model to obtain a design space mesh with one or more associated properties for each cell;
employing the first physical-to-design space mapping to map a first set of faults from the first physical space geologic model to the design space mesh;
employing the second physical-to-design space mapping together with the design-to-design space mapping to map a second set of faults from the second physical space geologic model to the design space mesh;
partitioning cells in the design space mesh along the first set of faults to obtain a first partitioned design space mesh with one or more associated properties for each cell;
partitioning cells in the design space mesh along the second set of faults to obtain a second partitioned design space mesh with one or more associated properties for each cell;
reverse mapping the first and second partitioned design space meshes and properties for each cell to physical space to obtain for the first and second physical space geologic models associated first and second physical space simulation meshes having one or more associated properties for each cell; and
outputting the first and second physical space simulation; and extracting hydrocarbons from a hydrocarbon-bearing formation using data from the first and second physical space simulation meshes.
