A Full-Field Simulation Study of the Effect of Foam Injection on Recovery Factor of an Iranian Oil Reservoir

In some of Iranian oil reservoirs gas is injected for pressure<br>maintenance as well as displacement of oil by gas. In some of<br>these fields, it comes to a premature breakthrough of injected<br>gas due to high permeability in some regions of the reservoir<br>or because of the geometry of the reservoir.<br>Foam injection appears to be a promising tool in solving<br>the problem with thief zones and low recovery from EOR<br>methods such as immiscible gas injection in Iranian oil<br>reservoirs. It can also mitigate the effect of gravity override<br>and achieve increased displacement efficiency in these<br>reservoirs.
