Discharge and intake pressure

[Mostafaelec86]

Dear all

i have a case that well is running with Discharge pressure less than Intake pressure,well is 60 % WC

pi 2960 psi
pd 2881 psi
ti 230 F
tm 275 F

Well is running on 34 A @ 50 hz and flow is mixed of Gases and water,

if we have a case like this, what is the reason that causes Discharge pressure to be less than Intake pressure?

You should define where those are, but I assume you're talking abouit inlet and outlet pressure into a downhole pump?

Flowrate more than the pump can handle?
Pressure transmitters not reading right?
What were they before?
Flowrate?
Depth of well?
Pressure at the surface?

The pressure of the column of fluid (including gas content) being lifted up is lighter than the sum of the pressure of the column of fluid being pumped down + bottom hole pressure - flow losses.

When gas content of the produced fluid increases, surface discharge pressures increase, because of less lifted weight in the discharge column and usually a lower frictional flow loss of gas.

So it looks like your pump is actually reducing the flow very slightly, but not really doing anything it would seem...

Maybe it's creating a lower pressure at the well base than would otherwise be the case?

I thought he was talking about the well inlet and discharge pressures, not the pump pressures.
"The well is running". He does not say "the pump is running".
If its pump pressures, reduce the flow, or increase its speed.
