Abstract
A method and system for producing fluid from a subsea wellbore. An amount of fluid is sampled from fluid being produced and retained for a period of time until constituents in the fluid stratify. A fluid characteristic is sensed at spaced apart vertical locations in the sampled fluid. A water fraction as well as gas content can be ascertained from sensing the sampled fluid. The fluid characteristic is used for calibrating a multi-phase flowmeter that measures flow of the fluid being produced from the wellbore.
