The “PIK-SLIMTUBE” installation for studying dynamically mixed fluids filtration

The PIK-Slimtube installation is designed to study fluids dynamic mixing processes (determine minimum miscibility pressure) at reservoir conditions on a sand packed tube.

 A long (24 m) thin (3.2 mm diameter) tube filled with prepared quartz sand is used as a reservoir model. During the experiment, recombined oil is displaced from the reservoir model by gas (hydrocarbon, nitrogen, carbon dioxide, etc.) or liquid solvent to evaluate the displacement efficiency depending on the discharge pressure. Viewing window with a video recording system provides visual control of outgoing fluid nature. The outgoing fluid volume is measured with a burette, and the gas – with a gas meter.

 The installation can be equipped with a chromatograph and high pressure densitometer for continuous monitoring of outgoing fluid composition and properties during the experiment.
