RESUMO
The injection of tracers are used in the investigation of ows in heterogeneous porous media, in studies related to the simulation of miscible dispacements in petroleum reservoirs and the dispersion of contaminants in aquifers. In this work we present new algorithms for the numerical approximation of tracer injection problems. We discuss recent developments of the Forward Integral-Tube Tracking (FIT) scheme which was introduced in Aquino et al. (2007a). The FIT is a locally conservative lagrangian scheme for the approximation of the linear transport problems. This scheme does not use analytic solutions of Riemann problems and is based on the construction of the integral tubes introduced in Douglas Jr. et al. (2000b). The FIT scheme is computationally very ecient and is virtually free of numerical diffusion. Numerical results are presented to compare the accuracy of the solutions provided by new implementation of the FIT scheme for the injection of tracers in petroleum reservoirs.
