Overburden core saturator


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.
