Abstract

In this study, four commonly injected EOR gases, CH4, N2, Air, and CO2, have been simultaneously investigated through an experimental method to determine the effect and correlational relevance of 28 structural and 22 fluid quantities to mobility ratio integrity. An experimental method involving five analogous structural strategies has been conducted. A total of 1,920 experimental runs were executed, and 15,360 data points were generated. The results revealed that the mobility ratio is significantly affected by the structural and fluid realities of the EOR process. The mobility integrity for the four gases were correlated to Reservoir Quality and Transmissibility variations the most. Overall the mobilities of the four gases experienced correlational variations for 12 structural parameters. Fourteen of the fluid properties have correlational relevance to CH4 mobility. N2 and CO2 have 11, and Air has 10. The findings from this study can be directly applied in selecting suitable injection gas and screening reservoirs so that the correlational dynamics are favourable to mobility objective and integrity, thereby optimising oil recovery in hetrogeneous reservoirs.
