As both the demand of CO2 sequestration and the huge potential of enhanced recovery make CO2 injection a popular method, cyclic CO2 injection is applied to mitigate effects of a condensate bank in an Eagle Ford shale condensate reservoir and to reduce greenhouse gas emission. Roles of multicomponent adsorption modeled by an Extended Langmuir model and geomechanics modeled by both a modified Barton-Bandis Model and a novel hysteresis rebound model are investigated during primary recovery and CO2 enhanced recovery. The results display that the impacts of multicomponent adsorption on well productions are limited for both processes. The main reason is that the reservoir pressure is still much higher than the Langmuir pressure even after 10 years' production, while a slight difference in the geomechanical model results in an almost doubled initial gas rate. The results of simulation coupled with a hysteresis rebound model show that more hydrocarbons can be produced, and more CO2 can be stored during cyclic CO2 injection. This paper presents operators with a clear view of effects of multicomponent adsorption and an insight into geomechanical effects.
