Özet

This paper presents several analytical models for the pressure distribution in hydraulically fractured reservoirs depleted by horizontal wells with the aid of cyclic CO2 injection. The objective is to eliminate uncertainties in predicting reservoir performance after the enhancement by CO2 injection and develop accurate tools for designing CO2 injection projects. This paper's primary purpose is to present novel analytical models for flow regimes and validate them. The proposed models are unique because they are derived without using an approximated approach, they consider multiphase flow and can be utilized for injection applications.
