Publication number: 20010030063Abstract: A rotary drag bit and method for drilling subterranean formations including a bit body being provided with at least one cutter thereon exhibiting reduced, or limited, exposure to the formation so as to control the depth-of-cut of the at least one cutter, so as to control the volume of formation material cut per bit rotation, as well as to control the amount of torque experienced by the bit and an optionally associated bottomhole assembly regardless of the effective weight-on-bit. The exterior of the bit preferably includes a plurality of blade structures carrying at least one such cutter thereon and including a sufficient amount of bearing surface area to contact the formation so as to generally distribute the weight of the bit against the bottom of the borehole without exceeding the compressive strength of the formation rock.Type: ApplicationFiled: December 15, 2000Publication date: October 18, 2001Inventors: Mark W. Dykstra, William Heuser, Michael L. Doster, Theodore E. Zaleski, Jack T. Oldham, Terry D. Watts, Daniel E. Ruff, Rodney B. Walzel, Christopher C. Beuershausen

Publication number: 20010030064Abstract: A self-contained excavation device, with specific application as a beach umbrella excavator and anchor apparatus, includes a cutting head with a stepped cutting edge to penetrate thin shell layers, recesses defining anchor shelves to prevent pullout from wind, and anchor sweep faces for severing a structural connection between the compacted formation material and the recesses for easy removal of the device. The self-contained excavation device also includes a pressure limit chamber to prevent overpressure of the drilling fluid, a floating piston with straight intake ports for easy maintenance, and a self-cleaning valve to prevent debris from accumulating and clogging the valve.Type: ApplicationFiled: February 22, 2001Publication date: October 18, 2001Inventor: Michael C. Thompson

Publication number: 20010030065Abstract: A PDC-equipped rotary drag bit especially suitable for directional drilling. Cutter chamfer size and backrake angle, as well as cutter backrake, may be varied along the bit profile between the center of the bit and the gage to provide a less aggressive center and more aggressive outer region on the bit face, to enhance stability while maintaining side cutting capability, as well as providing a high rate of penetration under relatively high weight on bit.Type: ApplicationFiled: May 14, 2001Publication date: October 18, 2001Inventors: Christopher C. Beuershausen, Mark W. Dykstra, Roger Fincher, Roland Illerhaus, Steve R. Matson, James A. Norris, Michael P. Ohanian, Rudolf C.O. Pessier

Publication number: 20010030066Abstract: A rotary cone drill bit is provided with enhanced fluid flow near the bottom of an associated borehole resulting in improved removal of cuttings and other debris from the bottom of the borehole. The drill bit includes a plurality of fluid passageways extending from the bit body to the exterior of the drill bit. The bit body may include an enlarged cavity with the fluid passageways extending therefrom. One end of the cavity preferably includes an opening to receive fluid from a drill string attached to the drill bit. The end of the cavity opposite from the opening may have a generally parabolic configuration. For one application, a web member extends from the lower portion of the bit body, occupying a void area between each cutter cone assembly. The web member preferably contains a plurality of fluid passageways which direct drilling fluid from the drill string, through the bit body, through the web member, and exiting at nozzles adjacent to the bottom of the associated borehole.Type: ApplicationFiled: February 16, 2001Publication date: October 18, 2001Inventors: Graham MacDonald Clydesdale, Alan Dee Huffstutler, Harry Morales Campos, Edward Charles Spatz, Lawrence Lee Tso

Publication number: 20010030067Abstract: A method is disclosed comprising the steps of locating, on a surface of a downhole component, a plurality of thermally stable polycrystalline diamond (TSP) bearing elements, and then applying to the surface a settable facing material which bonds to the surface between the bearing elements and embraces the elements to hold them in place. A method in which bearing elements each comprising a body of TSP at least partly surrounded by a layer of less hard material are secured to the surface by welding or brazing part of the surface of each bearing element which comprises said less hard material to said component is also described.Type: ApplicationFiled: March 6, 2001Publication date: October 18, 2001Inventors: Stephen Martin Evans, Terry R. Matthias, Tom Scott Roberts
