Abstract

Summary

The main objective of DFN models is to accurately represent the fractures-matrix effect on the porosity and permeability which condition the dynamic behavior of the reservoir. However, this process can be laborious and high computing demanding. Therefore, we propose an approach to consider the fractures in a single medium using a Multipoint Statistic Model which represents the fracture (joint) pattern and the matrix with its associated petrophysical properties.

Through a synthetic case of a fractured reservoir, we compare both techniques: DFN and MPS. A complete DFN modelling workflow is applied generating several realizations to select the representative case. The base case is compared with a bunch of MPS matrix-fracture model realizations which have been ranking using streamlines. In fact, we demonstrate that MPS matrix-fracture models give comparable results to a DFN model in a reducing time.

This approach will provide a comparable result as a full DFN model simulation and a faster assessment of the dynamic behavior of the reservoir, avoiding the time-consuming and the complexity of DFN methodology. Geological uncertainties are also taken into account by generating several realizations and ranking them to obtain the best flow scenarios that reproduce more accurately the conditions observed in the reservoir.
