Abstract
A method and apparatus for cleaning a rock core sample loads the sample into a cell where it is supported within an interior chamber of the cell. For at least one interval of time, the sample is soaked with a liquid phase solvent pressurized at elevated pressure and temperature without any flow of the liquid phase solvent into, through, and out of the chamber. The liquid phase solvent is then allowed to drain from the cell. The cell can include a fluid inlet and outlet that are both in fluid communication with the chamber. A controller can be used to control at least one parameter related to the soaking. The at least one parameter can be selected from the group consisting of i) the duration of the time interval, ii) pressure of the liquid phase solvent during the time interval, and iii) temperature of the cell during the time interval.
