Claim 14:
15. A geologic modeling method for extracting hydrocarbons, the method comprising:
obtaining a physical space geologic model representing a subsurface region in physical space;
mapping the physical space geologic model to a design space model which represents an unfaulted subsurface region;
gridding the design space model to obtain a design space mesh with one or more associated properties for each cell;
employing a physical-to-design space mapping to map a first set of faults from the physical space geologic model to the design space mesh;
partitioning the cells in the design space mesh along the first set of faults to obtain a partitioned design space mesh with one or more associated properties for each cell;
reverse mapping the partitioned design space mesh and properties for each cell to physical space to obtain a first physical space simulation mesh having one or more associated properties for each cell, wherein said mapping employs a first design-to-physical space mapping;
mapping the partitioned design space mesh and properties for each cell to a second physical space to obtain a second physical space simulation mesh having one or more associated properties for each cell, wherein said mapping employs a second design-to-physical space mapping; 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.
