The pressure equation is aproximated by Galerkin's method and the velociity field computed through a post-processing approach to recover the required accuracy. The concentration equation is approximated in space by the Streamline Upwind Petrov Galerkin (SUPG) plus a discontinuity-capturing operator. The resulting semi-discrete equations are approximated in time by a predictor-multicorrector algorithm. The pressure, velocity and concentration linear systems of equations are solved with parallel element-by-element iterative techniques. Performance measurements on the CRAY YMP and the CRAY C90 for the injection of tracer on a five-spot pattern with random small scale permeability variations are performed to demonstrate that the numerical techniques employed are accurate and result in a fast code.  aSimulação  aMathematical model  aModelagem  aSimulation of tracer injection1 aALVES, J.
