Reservoir Models for Input into Flow Simulators

  • F. Jerry Lucia


Reservoir characterization is defined as the construction of realistic three-dimensional images of petrophysical properties to be used to predict reservoir performance. A key element in constructing reservoir models is modeling the high and low permeabilities. In the past, these images have been prepared by several different methods including (1) the layered reservoir method, (2) the continuous pay method, and (3) the facies method (Fig. 1). In the layered reservoir method, the reservoir is divided into pay zones using correlations based on gamma ray logs, and the net feet of porosity (net pay maps) or the porositytimes-oil-saturation (SoPhiH maps) isopached for each layer. The layers commonly lump several petrophysical rock types, and the average petrophysical values do not characterize the flow properties of the reservoir.
