Percussion Drilling Assembly And Hammer Bit With Gage And Outer Row Reinforcement

View page
US Patent:
8387725, Mar 5, 2013
Filed:
Apr 14, 2008
Appl. No.:
12/102324
Inventors:
Shantanu Swadi - Cypress TX, US

Alan J. Marshall - Lost Creek WV, US
Assignee:
Smith International, Inc. - Houston TX
International Classification:
E21B 10/36
US Classification:
1754201
Abstract:
A hammer bit for drilling a borehole in earthen formations comprises a bit body having a bit axis and a bit face. The bit face includes an inner region extending from the bit axis to about 50% of the bit radius and an outer region extending from the inner region to the outermost radius. In addition, the bit comprises a plurality of gage cutter elements mounted to the bit face in a circumferential gage row in the outer region. Further, the bit comprises a plurality of adjacent to gage cutter elements mounted to the bit face in a circumferential adjacent to gage row in the outer region. The cutting profile of at least one cutter element in each row in the outer region radially overlaps with the cutting profile of at least one other cutter element in a different row in rotated profile view.

Percussion Drill Bit With V-Shaped Splines

View page
US Patent:
20070137895, Jun 21, 2007
Filed:
Dec 21, 2005
Appl. No.:
11/313551
Inventors:
Alan Marshall - Lost Creek WV, US
Shantanu Swadi - Cypress TX, US
Assignee:
Smith International, Inc. - Houston TX
International Classification:
E21B 10/38
US Classification:
175057000, 175293000, 175414000
Abstract:
A drill bit is disclosed for use in a percussion drilling apparatus of the type for boring into the earth. Embodiments of the drill bit comprise an elongate body with a first end, a second end, and a longitudinal surface extending between the first and second ends. Embodiments further comprise a plurality of splines on the longitudinal surface of the drill bit, with at least one of the plurality of splines comprising an apex, a root, and a planar surface between the apex and root. In preferred embodiments, the planar surface is oriented at an angle between 10 and 45 degrees to a plane extending from a center of the drill bit to a midpoint of the apex.

Inline Bladder-Type Accumulator For Downhole Applications

View page
US Patent:
20070284010, Dec 13, 2007
Filed:
Jun 8, 2006
Appl. No.:
11/449046
Inventors:
Lance D. Underwood - Cypress TX, US
Shantanu N. Swadi - Cypress TX, US
Assignee:
Smith International, Inc. - Houston TX
International Classification:
F16L 55/04
US Classification:
138 30, 138 31, 138 26
Abstract:
An accumulator comprises a housing connected to a hydraulic system, an elastomeric bladder separating a gas compartment from a fluid compartment, and an anti-extrusion device. A method for operating an accumulator comprises connecting the accumulator to a hydraulic system, injecting an inert gas into a gas compartment to a precharge pressure, moving an anti-extrusion device to prevent a bladder from extruding into the hydraulic system, running the accumulator and the hydraulic system downhole, moving the anti-extrusion device to allow fluid communication between the hydraulic system and a fluid compartment, generating pressure fluctuations within the hydraulic system, and expanding or contracting the bladder in response to the pressure fluctuations without moving the anti-extrusion device. A method of improving fluid hammer performance comprises connecting the fluid hammer to an accumulator that produces a greater delivered horsepower from the fluid hammer as compared to a baseline horsepower when operating without the accumulator.

US Patent:
20100236835, Sep 23, 2010
Filed:
Mar 19, 2009
Appl. No.:
12/407338

James A. Simson - Meadows Place TX, US
Assignee:
Smith International, Inc. - Houston TX
International Classification:
E21B 10/36
US Classification:
175417
Abstract:
A percussion drilling assembly includes an outer tubular, an inner tubular coupled within the outer tubular, a drill bit slideably disposed within the inner tubular, and a locking system that is actuatable by translation of the drill bit relative to the locking system, whereby the locking system is configured to prevent rotation of the inner tubular relative to the outer tubular in at least a first direction. In some embodiments, the locking system includes a plurality of locking members, each rotatable between an engaged position, wherein the inner tubular is prevented from rotating relative to the outer tubular in the first direction, and a disengaged position, wherein the inner tubular is rotatable relative to the outer tubular in a second direction opposite the first direction. In other embodiments, the locking system includes a locking member which is extendable to prevent rotation of the inner tubular relative to the outer tubular in at least the first direction.
