Abstract: Methods for modeling and simulating fractured subterranean volumes include a method including obtaining geological data representing a subterranean volume, generating a structural model thereof in depositional space and in structural space. The method includes selecting a first cell and a second cell in the model, the first and second cells being juxtaposed in geological space and defining a fault face where the first and second cells are intersected by a fault, identifying a first point on the fault face, and calculating slip curves. Respective slip curves originate at the point and extend across the fault in geological space to a respective second point of a plurality of second points. The second points are co-located with the first point in the depositional space. The method includes calculating fault rock properties at the first point based on the slip curves and adjusting the model to include the fault rock properties.

Abstract: A method, apparatus, and program product evaluate fracture abundance in a subsurface formation by modeling a fracture network in a three-dimensional volume using geometric primitives and based at least in part on geomechanical simulation of mechanical properties of the subsurface formation.

Abstract: A method, apparatus, and program product utilize projection-based area operations to accelerate the determination of subsurface structure parameters for subsurface structures such as fractures, faults and horizons in a subsurface formation.

Abstract: A method can include mapping a stairstepped grid to a surface where the stairstepped grid and the surface represent a discontinuity in a geologic environment; based at least in part on the mapping, adjusting properties associated with the stairstepped grid to compensate for spatial discrepancies between the stairstepped grid and the surface; and simulating flow in the geologic environment using the stairstepped grid and the adjusted properties.

Abstract: A method, apparatus, and program product evaluate fracture abundance in a subsurface formation by modeling a fracture network in a three-dimensional volume using geometric primitives. A fracture abundance parameter, e.g., a P32 fracture density, may be determined in part based upon the combined areas of the primitives with cells of a three-dimensional grid.
