ABSTRACT:
The method includes circulating steam, solvent or fluids through a material such as sand while constantly agitating the material to scrub and wash entrained substances such as oil, bitumen or the like free whereupon the substances are carried back to the surface. A vibrating probe assembly is utilized which is highly maneuverable and which fluidizes the sand immediately surrounding same thus facilitating the movement of the probe and assisting in the scrubbing and separating action of the solvents or steam upon the sand. The probe includes means for extending same into the sand to the bottom of a well bore so that the vibration in conjunction with the probe configuration moves the probe through the sand in a horizontal plane or, if desired, up and down at an angle from the horizontal. The voids remaining in the clean sand are filled with water so that the probe floats on the surface of the water. The substances which have been separated from the sand normally float on the water to the well bore and thence may be elevated to the surface by the pressure of the steam, solvent or fluid circulation.
