Краткое описание

Water alternating gas injection has been proposed as a method to increase reservoir oil recovery; however, the three-phase flow occurring in this process is somewhat difficult to describe, and many basic data are needed, including the three-phase relative permeabilities. We present measurements from petrophysical data, flowing tests, and analytical calculations for a three-phase flow process. The displacements have been conducted in a steady-state mode. In the analytical calculations we use the water, oil, and gas continuity equations. We solve this hyperbolic system of partial differential equations by the method of characteristics and symbolic calculation facilities. The literature describes the methodology to calculate bank propagation. Here we use a similar methodology to compare the experimental and analytical results to access the validity of the methodology.
