The Scaling of the Gas-assisted Gravity Drainage Process Using Dimensionless Groups

Abstract

Scaling of the gas-assisted gravity drainage process using inspectional analysis leads to a better understanding of the process. Seven scaling groups were derived by using inspectional analysis for the gas-assisted gravity drainage process and were reduced to five independent dimensionless groups. Based on these five dimensionless groups, a new dimensionless group was proposed for better representing all factors and forces that affect the process. The newly proposed dimensionless group was derived from experimental data in the literature and was validated by using reservoir simulation data. This number that is derived from experimental data in the core scale can predict oil recovery in reservoir scale by some modification in gravity number.
