Dear gents
What could possibly cause a well producing 1400 BPD, to produce 700 BPD intake pressure inc and discharge pressure Dec,amp is constant.
Production engineering open chock more and increase frequency, nothing happened what cause that!?
Please advise

RE: esp troubleshooting
If upstream pressure does not change with opening the choke beyond where you did see an increase in pressure on closing, then I would suspect that there is a new restriction in the tubulars upstream of the choke. Scale is a common suspect. I'd run a slickline gauge tool before I did much else.
It is very hard to believe that current, suction pressure, and discharge pressure were unchanged with a 50% reduction in flow rate. ESP's can be counter intuitive, but not that counter intuitive. Mostly the ESP power vs flow curve only gets squirrely as you approach the maximum pump head or as flow drops towards zero. Dropping rate from 14,000 to 7,000 certainly takes you to a different place on the efficiency curve, but still within the operating envelope.

I closed chock and WHP raised from 150 psi to 500 psi in 13 minits, then they did a backwash.job with diesel and and.operator the pump, nothing changed, low rate with low discharge pressure and increase intake pressure, the sample is heavy oil and gases
