Prediction of liquid recovery from a gas condensate reservoir
The primary purposes of this research are to predict the behavior of gas condensate reservoirs, and predict the recovery of liquid hydrocarbons from these reservoirs. Factors involved in liquid recovery are fluid phase behavior (retrograde condensation and liquid revaporization), reservoir heterogeneity, perforation strategies, gas injection versus depletion, cross flow between reservoir layers, injection gas fingering, and pattern geometry. The first factor is extremely important to predicting liquid recovery from a gas condensate reservoir. In order to evaluate fluid phase behavior, an equation of state material balance compositional model was developed to simulate the condensate liquid recovery from laboratory constant volume expansion (CVE) experiments and liquid revaporization in the reservoir that results from dry gas injection. The second factor was evaluated using a multi-purpose 3 phase, 3 dimensional simulator to predicting gas and liquid recovery for development of two different field areas. The last five factors were evaluated by employing a compositional simulator and multiple sector models. Conclusions are summarized.
