Drill Bit With Integral Cuttings Splitter And Method Of Making
US Patent:
2011021, Sep 1, 2011
Filed:
May 11, 2011
Appl. No.:
13/105365
Inventors:
Timothy K. Marvel - The Woodlands TX, US Michael R. Wells - Lakewood CO, US
Assignee:
BAKER HUGHES INCORPORATED - Houston TX
International Classification:
B29C 33/42
US Classification:

Core Bit Having Features For Controlling Flow Split
US Patent:
7055626, Jun 6, 2006
Filed:
Mar 15, 2002
Appl. No.:
10/099873
Inventors:
Michael R. Wells - Lakewood CO, US Luc Van Puymbroeck - Kingwood TX, US Holger Stibbe - Humble TX, US
Assignee:
Baker Hughes Incorporated - Houston TX
International Classification:
E21B 49/02, E21B 10/02, E21B 10/61
US Classification:
175 58, 175393, 175404
Abstract:
A core bit for cutting core samples in subterranean formations. The core bit has interior geometric features configured to control the quantity of drilling fluid, or flow split, flowing into a narrow annulus defined by an inside diameter of the core bit and an outside diameter of a core shoe. Reducing the flow split minimizes fluid invasion of a core being cut; thus, the core bit provides increased core quality and recoverability. The core bit is also adaptable for use with conventional core barrel assemblies and conventional coring techniques.
System, Method, And Apparatus For Variable Junk Slot Depth In Drill Bit Body To Alleviate Balling
US Patent:
7694755, Apr 13, 2010
Filed:
Oct 15, 2007
Appl. No.:
11/872069
Inventors:
Timothy King Marvel - The Woodlands TX, US David A. Trivas - Houston TX, US Michael R. Wells - Lakewood CO, US
Assignee:
Baker Hughes Incorporated - Houston TX
International Classification:
E21B 10/43
US Classification:
175398
Abstract:
An earth boring drill bit design for alleviating balling varies the junk slot depth in junk slots subject to balling from the other junk slots. Using variable depth bit bodies enhances the hydraulic characteristics of the bit as well as assists in the placement of the nozzles for machining purposes. This flexibility optimizes the area changes along the ducts required by the bit's operation.
Method And Apparatus To Thwart Bit Balling Of Drill Bits
US Patent:
2010027, Oct 28, 2010
Filed:
Apr 28, 2009
Appl. No.:
12/431204
Inventors:
Michael R. Wells - Lakewood CO, US Timothy K. Marvel - The Woodlands TX, US Chad J. Beuershausen - Magnolia TX, US
Assignee:
BAKER HUGHES INCORPORATED - Houston TX
International Classification:
E21B 10/00, E21B 10/42
US Classification:
175 57, 175426, 175435
Abstract:
Disclosed herein is a drill bit. The drill bit includes, a body of the drill bit having at least two blades defining a junk slot therebetween, at least one cutter positioned on at least one of the at least two blades, and at least one diverter positioned downstream of the at least one cutter defined by a direction of travel of the cuttings, the at least one diverter configured to divert cuttings to travel along a trajectory more parallel to a profile of the junk slot.

US Patent:
8146688, Apr 3, 2012
Filed:
Apr 22, 2009
Appl. No.:
12/427980
Inventors:
Timothy K. Marvel - The Woodlands TX, US Michael R. Wells - Lakewood CO, US
Assignee:
Baker Hughes Incorporated - Houston TX
International Classification:
E21B 10/46, E21B 10/58, E21B 10/62
US Classification:
175430, 175378, 175426, 175434
Abstract:
A downhole drill bit includes, a body, a plurality of cutters attached to the body, and at least one prefabricated splitter having a proximal portion and at least one distal portion. The proximal portion is encased within the body and the at least one distal portion extends outwardly of the body. Further the at least one distal portion is in operable communication with at least one of the plurality of cutters such that the at least one distal portion bifurcates cuttings cut by the at least one cutter.
