Abstract

Summary

The pressure and temperature changes play an important role in the productivity during SAGD process. In the present study a simplified geomechanical model has been added to the reservoir simulation in order to take into account the petrophysical properties modification induced by significant pressure and temperature variations. Our reservoir model is based on the 3D outcrop observation which contains a number of heterogeneities at various scales and the porosity and permeability are defined from measured data of core plugs of heavy oil field. As a first approach, we used a semi-analytical formulation to describe the pressure and temperature dependence of the petrophysical properties. We demonstrated that the productivity is underestimated if the pressure and temperature effects are ignored in the reservoir simulation. Thus, it is essential to properly take into account the geomechanical effect on the petrophysical properties for a better productivity estimation.
