Experimetal Study and Numerical Modelling of the Effect of Foaming Agent Properties on Foam Flooding in Porous Media in Absence of Oleic Phase
This paper presents an investigation on the effect of foaming agents perpropeties in tetms of surfactant concentration, interfacial tension (IFT) and foam strength during foam flooding in porous media in the absence of oleic phase. The experiments consisted of the co-injection of gas and various surfactant solutions with three different formulation properties in terms of IFT reduction and foaming strength capability into Bentheimer sandstone samples initially saturated with the surfactant solution. Experiments were performed using Bentheimer sandstone cores during, where X-ray CT images were taken during foam generation to find out the stability of advancing front of foam propagation and to map the gas saturation for both the transient and steady-state flow regimes.
Then, a series of numerical simulation was conducted to investigate the effect of surfactant concentration on pressure drop across the core for the foam flooding in the absence of oil. 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, oil saturation and capillary number. To this end, the dry-out and gas velocity functions in the foam model were determined from the 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.
