Studying of the Effective Parameters on Enhanced Heavy Oil Recovery by steam injection

High viscosity of some crude oil makes difficult to recover with primary or secondary production methods. Therefore, thermal oil recovery techniques are recommended for the Enhanced Oil Recovery (EOR) of heavy oil. In this experimental study, steam injection was used to investigate the effectiveness parameters on heavy oil production rate. The result is shown that, by increasing pressure, steam reaches the breakthrough point sooner, but recovery decreases. If the oils are a little different in viscosity, recovery in the light oil is more than that in heavy oil. Also in the highly viscous oils and light oils, recovery in the heavy oil is much higher than in light oil.
