Effect of IFT Variations and Gravity Segregation on Gas Injection Process
Abstract/Contents
- Abstract
- This work is based on the analytical theory of multiphase, multicomponent gas drive in porous media. A brief review of the mathematical theory is presented. Analytical solutions are derived for dispersion-free, one-dimensional displacement processes in three component hydrocarbon systems. The effect of gravity and interfacial tension is included into the mathematical model through the introduction of mixed functions for the relative permeabilities at high and low interfacial tension and modification of fractional flow functions with respect to gravity. The phase equilibrium behavior is taken into account through the Peng-Robinson equation of state. A systematic study is performed on ternary systems with example solution presented under different circumstances. The effect of various initial oil and injection gas composition, variation in mobility ratio, gravity number and interfacial tension is studied. The solution construction method is then extended to the gas displacement process in condensate reservoirs, where gravity and interfacial tension play relatively more important roles.
