Three phase video separator Special core analysis Instruments

The three-phase video separator is a high precision visualization device enabling the separation and volumetric determination of produced liquid and gas phases during multiphase experiments at ambient conditions. A three-phase mixture first enters a vertical glass tube section, deemed the “separation tube”. The latter communicates at the top, middle and bottom with the “visualization tube” via three glass tube sections. There are three dedicated inlet and outlet ports for each of the three phases. The injection fluid will be ejected from the separator via its outlet. Gas being compressible, a wet gas meter is required to measure the quantities produced. By virtue of their incompressibility, produced water or oil can be determined from a mass balance on the system.

Under the action of gravity, the lightest fluid comes to rest above the heavier fluid while the heaviest fluid settles at the bottom. In the separation tube, an emulsion of all three fluids prevents accurate volume determination, whereas in the visualization tube, two neat interfaces can be observed. These interfaces are constantly monitored by two Degree-of-Freedom video cameras with integrated zoom. Placing a light behind the tube further facilitates discernment of the liquid/liquid and gas/liquid interfaces. A proprietary software interprets the streaming images and calculates produced fluid volumes and core saturation levels. The system is also perfectly suited for two-phase flow studies.
