Abstract

The effect of cold-water induced reservoir cooling on tertiary gas injection processes is investigated. Numerical and analytical models of fluid and heat flows are employed to analyse the reservoir cooling phenomena. For the conditions studied, the injected water cools a significant volume of the reservoir. The altered formation temperature distribution affects significantly the displacement and sweep efficiencies, from the phasebehaviour point of view. Equation-of-state and compositional simulation approaches are adopted to analyse and quantify this effect. It is shown that a partially cooled hydrocarbon formation. can bring about a significantly larger tertiary oil bank than that without considering the temperature alteration.
