A locally conservative Eulerian-Lagrangian method (LCELM) is described for the numerical solution of two-phase, immiscible displacement in a 3-D porous medium. This method, introduced by Douglas, Pereira, and Yeh for two-dimensional problems, is directly applicable to scalar nonlinear transport problems. We first describe the method and then discuss some issues related to its implementation. The result of a numerical experiment will be presented.
