Abstract
A cleaning system for oil and gas core samples includes a vapor extraction chamber configured to receive and drain liquid solvents, a movable portion including a movable tray, a lid and a sample cooler, a heater configured to provide heat to the chamber to produce heated and vaporized solvents, a vapor extraction chamber chiller, a controller, and a dryer. A method of cleaning oil and gas core samples includes a vapor extraction step and a drying step. The vapor extraction step includes transferring core samples into and sealing the vapor extraction chamber, heating liquid solvents and maintaining an elevated temperature and a positive pressure in the chamber until an extraction time expires, cooling and transferring the core samples out of the chamber. The drying step includes transferring the cleaned core samples into a dryer, drying the core samples until substantially free of solvents, and cooling the core samples.
