The Gas-Assisted Gravity Drainage (GAGD) process was developed as an alternative to conventional gas injection enhanced oil recovery (EOR) processes, which suffer from their inherent weakness of combating gravity segregation. The GAGD process, however, is aimed at taking advantage of this phenomenon and consists of using horizontal producers near the bottom of the payzone while injecting gas using vertical injection wells. It is hypothesized that the injected gas will rise to the top, thereby forming a gas cap while displacing reservoir brine/oil downward towards the producers. In this study, a single-well alternative to the multi-well GAGD process was investigated to …
