Abstract: A method of retarding sand build up in heavy oil wells involving a first step of providing a pumping apparatus with subterranean impellers coupled to a rotary top drive unit by a plurality of connective rods. The plurality of connective rods have fixed outwardly extending vanes that rotate with the plurality of connective rods and are configured to provide a supplementary lifting force. A second step involves positioning the plurality of connective rods in a heavy oil well having a circumferential sidewall. A third step involves activating the rotary drive unit to rotate the plurality of connective rods. The vanes attached to the connective rods assist in lifting sand to surface with the heavy oil.
