Abstract
Fluid flow in hydrocarbon reservoirs and consequently optimum scenario for hydrocarbon production, is heavily influenced by reservoir heterogeneities. Faults are one of the most common types of heterogeneity found in reservoirs. Leaky faults, baffles (limited extent faults) and complex multiple fault geometries are among the most complicated and important types of faults that are difficult to characterize. Leaky faults, unlike the sealing faults, are in partial communication with other portions of the reservoir. Because of faults' effect on reservoir connectivity and possible infill drilling plan for accessing all parts of the reservoirs, possible communication across the fault must be precisely modeled.
