Hello
Did you figure out what was wrong with your ESP? I have a situation where the intake pressure has increased much higher than the tubing pressure, and production declined by about 500 bbls/d. There is evidence of CaSO4 scaling. I am guessing scaling in the tubing is responsible for the...
Appreciate your reply David, Great point about gas columns in the well. In a continuously injecting well, I don't presume there would be gas in the wellbore.
To clarify, the wells are in a mature very high watercut >99% field. We are using the parting pressure to determine the maximum injection...
Hello Gents,
I am implementing a script to monitor injection wells setpoint for automation. From experience we know that some of the wells are injecting at 0 surface pressure or "vacuum" at reservoir condition. I want to catch wells that may be injecting at vacuum regardless of the surface...
Hello Sirs,
We recently had to shut in few wells and in the process were able to record pressure data for build-up analysis. The PIP was used to generate the following build-up log-log interpretation. Few of the wells were showing a long period of a shallow <1/2 slope on the derivative plot. It...
Hello all,
We recently had to bleed off an injection well due to high casing pressure. After purging the well, we collected oil and water samples. I am curious to know how Oil ended up in the casing, is this an indication of casing leak? We are testing the water to see if it is formation water...
