Field Experience Level Instruments and Water Cut Meters for Crude Oil
(OP)
We are seeking operational feedback on level instrument and water cut meter manufacturers and specific technology that has been applied successfully in the field for crude oil water emulsion interface detection and outlet oil water cut metering for 3 phase production and test separators. The application is for heavy crude primary and test separators, 22API with potential stable emulsions forming, no foaming issues. FPSO installation and ships movements considered.
On level instruments for interface detection with emulsion band etc. we would appreciate feedback on any experience and recommendations on potential instruments that have been used or retrofitted successfully in similar heavy crude FPSO applications.
We are putting in a 3 phase test separator with a water cut meter in the oil outlet and are expecting to get emulsion carryover and expect accuracy issues with the meter. We would appreciate any feedback on instrument selection that you may have or could recommend.
I am aware of some of the technologies available in the market place and the reputed vendor claims however the crux of the matter is what actually works in practice and has been proven. I would appreciate any feedback and or contacts you may have.
Many thanks

* Endress-Hauser "tuning fork" for point-level detection, i.e. level switches
* Drexelbrook vertical capacitance probe for continuous interface or point interface, e.g. tank or vessel interface level monitoring
* Robertshaw for wet oil cut probe in your test separator
I guarantee you _will_ have accuracy issues with your cut probe. You can only minimize the problems. Best to set up a rigorous calibration schedule, make sure you have representative samples in the test line, i.e. no oil slugging, and make sure there is no gas in the test line. Also, the physical configuration of the oil-out leg on the test separator has a huge effect on the accuracy and repeatibility of the cut probe.
Thanks!

what is thought of as the best cut probe currently available? varying conditions 15 gravity to 34. steam conditions, gas.
thanks,

Thank you.

For interface detection we have used several technologies and the best has been Tracerco by Synetix. It is very expensive though. Other things we have tried are optical feed back by using submursible cameras.
