Abstract
An automatic well test system (100) utilizes a two phase vortex separator 104 connected to a pair of Coriolis flowmeters (154, 166) to measure volumetric flow rates in three phase flow. Measurements are performed according to a process (P200) including an iterative convergence technique. Measurements are enhanced by the use of real time density and water-cut measurements from a water-cut meter (172) and a water density meter.

A multiphase flow measurement system for use in flow environments including multiple liquid phases and a gas phase comprising:
- means for separating an incoming multiphase flow into a majority liquid component having a majority liquid content with entrained gas and a majority gas component having a majority gas content;
- and
- means for measuring a flow rate of said majority liquid component when said majority liquid component contains entrained gas, wherein said means for measuring a flow rate of said majority liquid component uses a calculation to quantify flowrates of discrete liquid and gas phases in said majority liquid component, said calculation being selected from a group consisting of iterative convergent calculations, rigorous calculations, and combinations thereof.
A method of performing multiphase flow measurements in flow environments including a liquid phase and a gas phase, said method comprising the steps of:
- separating an incoming multiphase flow into a majority liquid component having a majority liquid content with entrained gas and a majority gas component having a majority gas content;
- and
- measuring a flow rate of said majority liquid component when said majority liquid component contains entrained gas, wherein said step of measuring a flow rate of said majority liquid component includes
- calculating to quantify flowrates of discrete liquid and gas phases in said majority liquid component, said step of calculating includes use of a calculation selected from a group consisting of iterative convergent calculations, rigorous calculations, and combinations thereof.
