Abstract
Summary
Natural faults are complex three-dimensional volumes with abundant displacement partitioning between individual fault segments. This displacement partitioning results in different across-fault and up-fault flow paths to those present in conventional faulted simulation models in which faults are represented as single planar surfaces. Recent research has focused on defining methods for (a) modelling realistic sub-seismic fault zone structure, and (b) representing this in flow simulation models. This presentation focuses on the second of these topics, and described a new, flow-based upscaling method that is more accurate, more flexible and easier to apply, than the existing geometry-based geometrical upscaling algorithm.
