چکیده مقاله:

This paper presents numerical simulations of foam flooding experiments into Bentheimer sandstone rocks in absence of oil. Numerical simulations were conducted to investigate the effect of surfactant concentration on pressure drop across the core for foam flooding. The foam model implemented is based on a local equilibrium and describes dependency of foam mobility reduction factor using several independent functions, such as liquid saturation, foam velocity, and capillary number. To this end, Parameters of the dry-out and gas velocity functions in foam model were determined from experimental data obtained at low and high-quality regimes of foam flow at a constant injection velocity. Next, pressure drop profiles of foam flooding at two different surfactant concentrations were modelled to determine the parameters of the surfactant-dependent function in the foam model. The simulation results fit the experimental data of pressure drops very well.
