Abstract
A permanent subsea sampling and analysis system is integrated into a replaceable equipment module for a choke valve of a subsea production well. The analysis system is self-contained, and separates a sample into liquid fractions consisting of crude oil, condensate and produced water and then measures the salinity of the water as well as the volumetric ratio between the liquid fractions all in the same sampling container.
