Theoretical predictions are obtained using both Eulerian and Lagrangian methods for calculating saturation profiles in two phase immiscible displacements in the presence of capillary effects. The one-dimensional simulator WFLOOD is described with Lagrangian and Eulerian options for refined calculations of saturation distributions throughout all stages of a linear core flood. WFLOOD calculations are presented to demonstrate typical waterflood performance in a one metre core using two different capillary pressure functions at high and low flow rates. Steady state and dynamic brine/tetradecane displacement experiments are described using Clashach sandstone cores with radioactive ferrocene in the oil phase for the measurement of saturation by a nucleonic method. The PORES reservoir simulation model provides a theoretical analysis of the experiments in which the non-uniform initial saturation distributions must be represented. It is shown that PORES, used in conjunction with measured steady state relative permeabilities and static capillary data, reproduces the time-dependent saturation profiles to within the accuracy of the measurements at high and low flow rates. The Lagrangian option in WFLOOD provides a theoretical benchmark which defines the levels of numerical dispersion present in the PORES Eulerian finite difference calculations.
