Slim-tube System

Slim-tube System

Manufacturer: Vinci Technologies
Model Number: sts-700

The STS 700 system excellently performs dynamic miscibility tests studies at reservoir conditions of temperature and pressure. Specifically, the miscibility tests allow for the evaluation of the minimum miscibility pressure (MMP), the minimum miscibility composition (MMC), the optimization of injection parameters and composition of lean and enriched gas, the determination of oil in place recovery and the assessment of experimental condition sensitivity on recovery. The gas to be tested is injected at a desired pressure through the slim tube previously cleaned and saturated with oil by means of a high pressure pump. The effluents flowing from the slim tube can be observed through a capillary sight glass tube. They are then expanded to atmospheric pressure and temperature through a back pressure regulator which maintains a constant system outlet pressure. The effluent liquid volumes are continuously monitored using a digital volume measuring detector whereas the produced gas is measured by a wet gas meter. The recovery curve is then plotted using the raw data obtained during the different miscible displacement experiments. Additional components such as a density meter or gas chromatograph may be added to the STS 700 to extend its capabilities.
