Abstract:
The goal of the project was to select between the application of waterflooding and gas injection in an actual carbonate field to ascertain which method would yield the highest recovery. This was done by performing reservoir simulation studies to observe the reservoir’s response to each of these methods. Various injection schemes, which included injection rates and location of injection wells, were simulated to obtain optimal recovery based on the setup of the injection wells, allowing for observation of the effects of injection rate, injection location, and injection start time on recovery. The performance of these enhanced oil recovery methods applied to the carbonate field studied in this report are captured and described.
