Patent number: 10472898Abstract: A superabrasive-impregnated earth-boring rotary drill bit includes cutting features extending outwardly from a bit body in a nose region of the drill bit. The cutting features comprise a composite material including superabrasive particles embedded within a matrix material. The cutting features extend from an outer surface of the bit body by a relatively high average distance. Methods of forming a superabrasive-impregnated earth-boring rotary drill bit include the formation of cutting features that extend outwardly from a bit body of a drill bit in a nose region of the drill bit. The cutting features are formed to comprise a particle-matrix composite material that includes superabrasive particles embedded within a matrix material. The cutting features are further formed such that they extend from the outer surface of the bit body by a relatively high average distance.Type: GrantFiled: November 12, 2015Date of Patent: November 12, 2019Assignee: Baker Hughes, a GE company, LLCInventors: Christopher J.

Patent number: 10445841Abstract: Systems and methods may be used to select a drill bit design for an earth-boring rotary drill bit for use in a particular drilling application. The systems may include a computer server, and a remote device configured to communicate with the computer server through a network. The computer server may include a database including information relating to normalized scores for a plurality of drill bit responses for a plurality of differing drill bit designs. The computer server may receive information from the at least one remote device, to select one or more potential drill bit designs from the at least one database based on the information, and to transmit information relating to the selected one or more potential drill bit designs to the remote device. Such systems may be used in methods of selecting drill bit designs for earth-boring rotary drill bits for use in respective drilling applications.Type: GrantFiled: April 8, 2015Date of Patent: October 15, 2019Assignee: Baker Hughes, a GE company, LLCInventors: John M. Meerdo, Scott F. Donald, Robert A. Laing, Danielle VeLoise Roberts, Chaitanya K. Vempati

Patent number: 10082003Abstract: A main bore is drilled and a treatment assembly is located. A packer is located to support a whipstock for drilling the lateral. This packer serves as a lower seal on a main bore diverter. The whipstock is installed on the packer and a mill drills a window and the lateral. The mill is pulled and the whipstock removed with a fixed lug tool. A bottom hole assembly is run into the lateral which includes a diverter that is landed by the window. If cementing is called for it is done at this time. A top string is installed that isolates the upper casing. The lateral is treated with the main bore isolated. The diverter is retrieved through the top string. The main bore diverter is run in through top string and landed in the junction with the window and lateral isolated. The main bore diverter is removed through the top string. The treatment bottom hole assembly has a series of sliding sleeves operated by a single size ball.Type: GrantFiled: May 16, 2016Date of Patent: September 25, 2018Assignee: Baker Hughes, a GE company, LLCInventors: Joseph Sheehan, Mihai Marcu, Dennis M. Collins, Jr., Scott F. Donald, Richard R. Lafitte

Patent number: 10047569Abstract: A cutting element for an earth-boring tool includes a volume of superabrasive material on a substrate. The cutting element has an elongated shape in a lateral dimension parallel to a front cutting face of the cutting element, and has a maximum lateral width in a first direction parallel to the front cutting face of the cutting element and a maximum lateral length in a second perpendicular direction parallel to the front cutting face of the cutting element. The maximum lateral length is significantly greater than the maximum lateral width. An earth-boring tool includes one or more such cutting elements mounted to a body of the earth-boring tool. A method of forming such an earth-boring tool includes selecting at least one such cutting element and mounting the cutting element to a body of an earth-boring tool.Type: GrantFiled: March 11, 2016Date of Patent: August 14, 2018Assignee: Baker Hughes IncorporatedInventors: Danny E. Scott, Scott F. Donald

Patent number: 9920575Abstract: Earth-boring tools include a cutting element positioned on a drill bit body at a radial distance from a longitudinal axis thereof. At least two formation-engaging elements are positioned at the same radial distance from the longitudinal axis as the cutting element. The formation-engaging elements are recessed from a cutting profile of the cutting element by a distance within about 10% of d, wherein d=(?*x)/(1800*y), where ? is an angle between the formation-engaging element and the cutting element, x is a rate of penetration of the drill bit body, and y is a rotation speed of the drill bit body. Additional earth-boring tools include at least one cutting element and at least two formation-engaging elements recessed from a cutting profile of the at least one cutting element at a common angle. Methods relate to forming such earth-boring tools.Type: GrantFiled: April 28, 2014Date of Patent: March 20, 2018Assignee: Baker Hughes IncorporatedInventors: Matthew J. Meiners, Scott F.
