Two Phase video separator Special core analysis Instrument

The apparatus separates the two expelled fluids from the core at reservoir conditions. Upon entering the separator, the mixture flows into a vertical bore, deemed the “separation bore”. The latter communicates at the top and bottom with the “visualization bore” via two horizontal bore sections. By virtue of gravity, the lighter fluid comes to rest above the heavier fluid. In the separation bore, an emulsion of both fluids prevents accurate volume determination, whereas in the visualization bore, a neat interface can be observed. The fluid interface in the separator is constantly monitored by a video camera with integrated zoom. Placing a light behind the tube further facilitates discernment of the liquid/liquid or gas/liquid interface. A proprietary software continuously displays the streaming images, interprets them and calculates the produced fluid volumes and core saturation levels.
