Overburden core saturator Core preparation and Core saturation Instruments

The overburden core saturator enables the end user to obtain remarkable saturation of clean, dry core samples at overburden pressure. Initially, the sample is placed in a Viton sleeve, in a hydrostatic core holder and the latter is evacuated by applying high vacuum for a few hours. Upon request, additional core holders can be added to the assembly. Once vacuum has been established, the saturation liquid, contained in a floating piston accumulator is injected by virtue of a High-Performance Liquid Chromatography (HPLC) pump capable of generating pressures up to 5,000 psi. Finally, a hydraulic manual pump generates a confining pressure on the walls of the Viton sleeve. These conditions should be maintained for at least four hours to guarantee maximum core saturation. This is confirmed by a stable reading on the manometer.
