Descriptions :

High water cut conditions can occur in water and steam flood productions as well as in maturing reservoirs. Measurement uncertainty of Net Oil using a 2-phase separator increases exponentially at high water cuts (>85%).

The Accuflow 3-phase separation metering system addresses this issue of measurement uncertainty at high water cuts by taking an additional step of separating water from oil. The Accuflow 3-phase Series consists of vertical pipe and a horizontal pipe sections connected together as shown. Production fluid (oil, water, and gas) enters the vertical pipe tangentially, creating a cyclonic action in the pipe where the majority of the gas is separated and flows upward to the gas flow line above. The remaining gas, in the form of small gas bubbles, is carried under with the liquid stream and enters the horizontal pipe.
