Abstract: The purpose of the method of the present invention is to provide an improved method and an improved apparatus, to displace light, medium, or viscous hydrocarbon fluid, which may be contaminated with earthen solids, from the subterranean hydrocarbon reservoir to a hydrocarbon fluid storage tank or other handling facilities on ground surface, by means of oil well production. The method is intended for use in cold primary hydrocarbon production or thermally stimulated hydrocarbon production from vertical, slant, whipstocked, or horizontal oil wells. The production system does not employ moving subsurface mechanical components.
