TCA & CCA pessure
TCA & CCA pessure
(OP)
higuys whats up
am a FSE and monitoring a well with ESP at a new compmany that use guage from measureng TCA & CCA prssure
first its my first time to deal with both parameters so can any one help me to undertnad them how they are calculated and what is the important of them and how they affect my pump performance and if there is any papers i can read to understand more.
secnd thing TCA was about 887 psi and WHP was 416 psi and Casing presure was 400 psi ,,,suddeny TCA value became -3.2 psi and WHP DEC TO 254 PSI AND casing PRESSURE Become 900 psi,,,,is that danger on pump ?
your help is higly appreciated.

RE: TCA & CCA pessure
Explain both a bit more, but changes like you've described don't sound good.
Remember - More details = better answers
Also: If you get a response it's polite to respond to it.
RE: TCA & CCA pessure
as i menioned above ,,at the well starting TCA was 800 psi and in a aweek it raised to 886 psi. during tis week Casing pressure remained 400 psi and CCA remained -1.2 psi. Production was decreasing but ampere was constant,,WHP WAS bout 417 psi with 50% CHOKE. ALL SURFACE GUAUGE ARE CONTROLLED BY Scada by the client i have no accese to change it from the well i jut inform them by phone.
from 3 days ago TCA dec to negative value -1.2 then to -3.2 PSI ,, WHP dec to 357 then 302 then 254 psi in 3 days,,choce in cto 60 % and production started to inc .
now y you say it doesnt sound good can you explain more?

Big changes like you describe are normally not a good sign, but this remains a very confusing set of data

Tubing is normally the inner tube, casing is an outer tube and annulus the gap between. Hence "Tubing casing annulus" makes no sense to me.
Needs a drawing or diagram of your system to try and make some sort of sense of this I'm afraid

Did someone perhaps vent down a casing or annulus which has no flowing fluid??
Get the P &ID and a description of flow before you go anywhere else.
