Test of a 1 inch Roxar Watercut meter on light condensate with very low water content

摘要

Condensate applications, close to a reservoir but after separation, are known to be very stable processes. The water content is generally very low, since water separates fairly easy from the condensate. Also, any process changes are generally slow, due to the fact that the condensate has had time to settle down and mix in the separator tank. On an application of light condensate with very low water content, it is possible to achieve very low measurement uncertainty with the method 'local characterization' implemented into the Watercut meter. The method is basically an advanced way of inline calibrating a meter, and taking into considerations local effects of different hydrocarbon compositions. The method will cancel out local effects on the special offset of the local hydrocarbon composition, as well as small local differences from the general correction of the density versus the hydrocarbon permittivity.
