On Modeling of Multiphase Flows in Fractured Media with Application to History Matching Problem

In the paper, study of some typical situations related to presence of fractured zones in the inter-well media is carried out using numerical simulation of multiphase flows. Such zones can be revealed particularly by interpretation of the electrical prospecting measurement data. With some degree of accuracy, it allows to determine the location and the orientation of the fracturing. It is known that fracturing has sufficient influence on the distribution of fluids in the reservoir in general and, in particular, on the production rates. Both these facts are confirmed by numerical simulations performed in this paper. Several approaches of fracture modeling are considered. These methods allow to avoid direct numerical fractures simulation associated with several difficulties due to a strong grid cells sizes heterogeneity and a permeability contrast. The comparison results demonstrate sufficient correspondence between methods concerned. The issue of model adjustment using measurement data is discussed. The methods described can be applied for the simulation of the real reservoirs.
