Experimental Evaluation of the Mobility Profile of Enhanced Oil Recovery Gases

The mobility profiles of gases used in enhanced oil recovery (EOR) have been thoroughly investigated through the coupling operations data mining oilfield and experimental analyses. Mobility as an EOR objective function has not previously applied to characterize potential reservoirs for selection application, even though it is a robust combinatorial that benefits from two petrophysical variables, permeability viscosity. approach identified reliable reservoir characterisation. distribution clustering results indicate Gas have relatively higher mean than Thermal, Microbial Chemical EOR reservoirs. approach gases, CO2, CH4, N2, Air. A modified Darcy Equation State for gas flow porous media was to evaluate which gas would competitively attain oil displacement optimisation criterion mobility ratio, M ≤ 1. Coupling with results reveals can be further categorized by mobility. CH4 (18.16 mD/cp) observed the highest followed Air (14.60 mD/cp), N2 (13.61 mD/cp), CO2 (12.96 mD/cp). order significantly corresponds that implemented processes. It concluded offers relatively lower mobility, therefore, most competitive to approach ratio unity or less.
