The “PIK-RP (a)” automatic installation for reservoir fluids samples recombination

The “PIK-RP (a)” installation is designed for recombination of wellhead (separated) oil / water samples and hydrocarbon gases for further PVT studies or filtration experiments.
The main installation element is a high-pressure piston tank (recombination cell) into which the required (usually in accordance with the working gas factor) fluids volumes are transferred using a plunger pump. Required phase volumes are calculated using installation software. The recombination cell swing mechanism and additional magnetic stirrer provide efficient fluid recombination.
