In damaged zones, cracks and geological faults generally have a great effect on the effective permeability of rock masses. One of the most important characteristics of naturally fractured rocks for simulating the flow in the hydrocarbon reservoir is permeability. Mapping fracture networks and estimating their properties such as porosity and permeability to be used as input data in simulation studies are two critical steps in modeling of fractured reservoirs.
Optimal Reservoirs’ Fault Damage Zone fracture network and associated Conduit Mapping is a deterministic method. We providing a reliable solution for structurally related conduits in fractured reservoirs mapping and characterization, using 3D seismic data. These conduits is identified and mapped by a three dimensional adaptive, multi-directional, multi-component logical operator. Mapping structurally related conduits, is lowering exploration and development costs.
Mapping small faults intersections can provide considerable information about fault damaged zones delineation and their associated conduits for fluid flow. These points of intersections are suitable indicators for conduit mapping because of the following reasons:
They strongly influence solute dispersion and channeled transport.
They integrate and focus the flow of liquid within a fracture network.
They have continuous flow behavior because of the enhanced capillary barrier effects and the connectivity of fracture networks, generally measured in terms of fracture intersections, because circulating flow in local flow cells arises from the interplay between distributed hydraulic potential along fracture intersections and no-flow fracture edges. Flow and transport in three dimensional fracture intersections may contribute to the re-distribution of solute.
