3-Phase Video Separator for Hi-Pressure, Hi-Temperature
Manufacturer: Vinci Technologies
Model Number: VSE-700-3
The apparatus segregates at reservoir-representative conditions, the components of a three-phase mixture expelled from a core sample. The separator’s wetted parts comprise two vertical bores communicating with each other via a narrow slot whose height equals that of the bores. The narrow slot enhances the phase segregation process. Upon entering the separator, the mixture flows into the first bore, deemed the “separation bore”. By virtue of gravity, the lightest fluid comes to rest at the top, the heaviest fluid, at the bottom, and the intermediate fluid, in the middle; in the separation bore, an emulsion of all fluids prevents an accurate volume determination, whereas in the other bore, two neat interfaces can be observed. Embedded in the separator wall, on the visualization bore is a see-through window cell made of two windows mounted opposite each other. The three level video tracker constantly monitors the position of the two interfaces. The position of the interface is directly proportional to the volumes of fluids produced from the core sample and hence the change in saturation profile. The system comprises three high-resolution cameras for each level, a back-lighting installed in the rear of the separator and an image processing software for data storing and monitoring. The latter can automatically detect fluid interface levels and computes both produced fluid volumes and saturation.

- The separator is a compact tool which can be easily installed into core flooding air baths.
- The full visibility of the produced phases enables the end user to simultaneously get phase volume changes and real time images of the water/oil and oil/gas interface heights. Cross checking between the actual images and calculated data is then possible.
- The use of three high resolution cameras to monitor a 10 cm column of produced fluids allows very accurate meniscus detection and thus volume changes.
