Multiphase Flow Meter for emulsified crude oil Production

Hi Als,
Can anyone explain for the application and accuracy of multiphase flow measurement for emulsified crude oil production fields.
Best Regards
 
Application - you can estimate the quantities of oil gas and water in a single pipe.

Accuracy - varies widely depending on the metering technique used, the ratio of oil / water / gas and the vendor claims. You often find that a certain meter or vendor is good for one ratio of components, but once you vary that by 30-40% the accuracy versus a separator gets more variable

Personally I don't think it gets much better than 10% and often a whole heap less in the field as the conditions vary so much, including how much slugging is going on.

An emulsified liquid phase would be difficult I suspect or need some sort of radioactive measurement device.

Best to do a trawl of the relevant vendor product data sheets and see how it matches your particular fluid.
 
As I review the literature, I’ve observed that the dielectric constant tends to vary frequently due to changes in conductivity and fluid density as well. This variability could significantly affect the accuracy of production flow measurements. I would appreciate hearing from field experts regarding their practical experiences. How have such variations impacted your measurement accuracy in real-world applications.
 
You're possibly in the wrong forum for that.

There is a Petroleum.set of forums allied more to field issues than plant issues
