... or submersible pumps. The pumps usually operate under constant withdrawal rate until gas breakthrough, at which time the pumping rate would be influenced by the presence of gas at the production side. It is evident that pumping rate dictates both pressure and fluid flow regimes in the volume which is under...

... and producer liquid withdrawal rate during different SAGD operation periods. Finally, experimental design and response surface generation techniques were applied to build a polynomial response surface through which the net present value (NPV) of the SAGD project is correlated with uncertain parameters...
