Abstract

This paper presents a coupled geomechancal and fluid flow simulation for a hydrocarbon reservoir in exploitation process. Two simulators have been used: 1. Geomechanical simulation software FLAC3D which uses Finite Difference Method and 2. tNavigator which is a Finite Element solver engin for fluid flow simulation in porous media. The parameters connecting fluid flow and geomechanical simulators mainly are porosity and reservoir pressure. Pore pressure changes in depletion process of reservoir cause changes in stress and strain tensor in hydrocarbon bearing and adjacent formations. Changes in spherical stress tensor in its turn cause a reduction in porosity, which affects the results of the fluid flow simulation. To verify the geomechanical computations, calculated stress distribution has been compared with analytical and empirical solutions. With coupled reservoir simulation we can predict flow rate for each well, recoverable reserves and also other required parametrs in reservoir life and production process, more accurate and reliable. We will be able to evaluate tensors of stress and strain for hydrocarbon bearing formations and adjacent layers. These stress data can be used in wellbore stability analysis in whole reservoir life.
