Hi Everyone, 


I would like to know if anyone have experienced the implementation of upstream wellhead dewatering processing unit in order to mitigate  very high water cuts experienced in specific producing reservoirs. We have existing pipeline systems which are expected to be overloaded with future associated produced water (with the produced oil) and which will surely suffer from emulsion high viscosity and increase in pressure drop. Any thoughts or experiences on how similar situations were resolved in worldwide projects?

If you have very high water cuts (>70%), the emulsion will have an apparent viscosity very close to that of water.

If you are lower than that, then yes the emulsion may be viscous (emulsion viscosity is as yet not a well understood science).  You can put separators at wellheads, but the problem then becomes what do you do with the produced water?  It likely requires processing of its own to get down to a disposable oil or salt content (don't know where you are or what your local regulations might be.

You need to define the phases with flow rate.

We have provided multiphase hydrocyclones for dewatering purposes, installed upstream of the production separators. We have many references, drop me a message I will be happy to provide.


Have a look at this:
