Computational Study of CO2 Injection for Enhanced Oil Recovery and Storage

Abstract

After a while of oil production from reservoir, pressure of reservoir will be decreased, and the rate of production will be decreased too as a result some oil will remain in the reservoir.

One of the main problems is choosing the best method for having better production.

The solution for increasing the reservoir pressure is injecting a fluid into the reservoir by a new well. It can be steam or gas or any other fluid. Different valves can be used in the well such as ICD or AICV. And, by decreasing the viscosity which affects directly on the mobility of oil and production rate. One of the best software which is effective for simulating the reservoir is CMG which is used in this thesis too.

As a conclusion, by increasing the injection of fluid in long period, more production can be achieved. And ICD can store more gas in the reservoir in compared to openhole which is so effective for environmental issues.
