| Summary: | Foam injection is one of the available Enhanced Oil Recovery (EOR) techniques in recovering the residual oil saturation after the application of the secondary recovery techniques. Foam injection makes use of the presence of the foam in the reservoir. In the case where gas is injected without the presence of foam, the mobility of the gas is high. This will lead to viscous fingering and gravity override of the gas. With the addition of the foam to the gas injection, the mobility of the gas will be low, minimizing the intensity of the viscous fingering and gravity override.
The generation of the foam, stability, and the effectiveness of the foam injection will be depending on how the foam is being injected into the reservoir. So, the objective of this project is to determine the best foam injection strategy. Precisely, we will be focusing on the details of the foam injection operation such as the surfactant concentration and injection rate along with when the injection to be carried out after a period of natural production (primary recovery).
In order to complete this task, we will be using ECLIPSE reservoir simulator to simulate the production performance of the reservoir model for several cases of foam injection. The cases will be varying according to foam concentrations and foam injection rates. |
