ABSTRACT:
A method and apparatus is provided for drilling high-angle, directional and horizontal subterranean wells for hydrocarbon extraction. A drillstring component having at least one helical undercut pumping chamber is described, which drillstring component is designed especially for increased flexibility in directional drilling applications. The undercut pumping chamber of the invention drillstring component is designed to improve volumetric efficiency in removing cuttings from the borehole, and to reduce the incidence of differential sticking or key-seating.
