APPLICATION OF BOUNDARY ELEMENT METHOD TO STREAMLINE GENERATION AND PRESSURE TRANSIENT TESTING

摘要: Reservoir geometry and heterogeneities significantly influence the flow field consequently pressure transient response in underground reservoir fluid flow. With advent of accurate instrumentation, it is important to include behavior complex systems design analysis procedures. Boundary element method used this work account for such effects. The usefulness lies fact that solutions obtained are highly do not suffer from usual drawbacks other domain type numerical schemes. Also geometries with multiple wells can be handled due good boundary conformance elements. Such desirable features realized because analytical nature solution preserved use free space Green’s function govi:ming differential operator as weighting weighted residual approach. A collocation resulting integral equations. Also, since a procedure, dimensions problem reduced by one. This, reduction dimensionality cases where there no distributed sources/sinks initial conditions homogeneous. restricts application linear problems constant coefficients. variety have been considered herein. Generation streamlines demonstrated odd shaped reservoirs wells. Two different formulations single phase fluids homogeneous anisotropic porous media also presented. Both
