Pump selection

Post by pank27 »

I have a well (Coal bed methane well ie. water production form tubing and gas production form annulus) which will be completed with a PCP. Casing size is 5 1/2" (ID-4.99"). how do i select a PCP on the stator OD??

I have to Stator one with 4.2" OD and one with 3.5" OD of same capacity?

If i select 4.2" there will be very less annular space for the gas to travel to annulus and major free gas would go to pump?? but i want to avoid gas into the pump.

my question is How does the annular space in the well affect the gas flow in the annulus??
