Abstract
In many oil producing regions in Egypt and worldwide, we have reached the stage where the total rate of production is nearing the decline phase. The older and larger fields face abandonment with 50%+ of the original oil in place (OOIP) unrecovered. This situation provides a major challenge: how to extract more oil economically and delay abandonment.
Using nano technology in the petroleum industry, especially Enhanced Oil Recovery (EOR) processes, revealed solutions to some of the challenges associated with old EOR techniques. This method that utilizes particles in the order of 1 to100 nm brings specific thermal, optical, electrical, rheological and interfacial properties which are directly useful to release the trapped oil from the pore spaces in the order of 5 to 50 microns of tight oil formations.
In this research, comprehensive literature review about the nanoparticles and its interactions with the porous medium will be presented. In addition, the core flooding and micro model studies for the application of the nano flooding for EOR will be introduced.
A new mathematical model for nanoparticles transport and retention for two phase flow porous medium will be developed. This mathematical model accounts for fluid saturation, the nanoparticles concentration distribution, the variation of the porosity and absolute permeability. Sensitivity analysis for the effect of different parameters like injecting nanoparticles concentration, dispersion coefficient and depositional factor on the fluid flow saturation, and nanoparticles concentration distribution through porous medium.
The mathematical model will be validated by using set of experimental data conducted by Haiyang for nanoparticles transport and retention in two phase flow water and oil through porous medium.
