Patent number: 10472908Abstract: An apparatus for use downhole is disclosed that, in one configuration includes a downhole tool configured to operate in an active position and an inactive position and an actuation device, which may include a control unit. The apparatus includes a telemetry unit that sends a first pattern recognition signal to the control unit to move the tool into the active position and a second pattern recognition signal to move the tool into the inactive position. The apparatus may be used for drilling a subterranean formation and include a tubular body and one or more extendable features, each positionally coupled to a track of the tubular body, and a drilling fluid flow path extending through a bore of the tubular body for conducting drilling fluid therethrough. A push sleeve is disposed within the tubular body and coupled to the one or more features.Type: GrantFiled: July 28, 2017Date of Patent: November 12, 2019Assignee: Baker Hughes Oilfield Operations LLCInventors: Steven R. Radford, Khoi Q. Trinh, Jason R. Habernal, R. Keith Glasgow, John G. Evans, Bruce Stauffer, Johannes Witte

Patent number: 10053917Abstract: Earth-boring tools may comprise rotatable cutting elements rotatably connected to protruding journals, which may be at least partially located within inner bores extending through the rotatable cutting elements. A rotationally leading end of one of the protruding journals may not extend beyond a cutting face of its associated rotatable cutting element. Alternatively, a protruding journal may comprise a chip breaker protruding from a cutting face of a rotatable cutting element. Methods of removing an earth formation may include directing cuttings forward, away from a cutting face of a rotatable cutting element when the cuttings reach an inner bore of the rotatable cutting element, and rotating the rotatable cutting element around a protruding journal at least partially located in the inner bore.Type: GrantFiled: October 23, 2017Date of Patent: August 21, 2018Assignee: Baker Hughes IncorporatedInventors: Suresh G. Patel, Bruce Stauffer

Patent number: 10024111Abstract: Downhole tools with a topographical pattern, and anti-balling material over the topographical pattern. The topographical pattern may be defined by at least one of a plurality of recesses extending into a surface of a body of the tool and a plurality of protrusions protruding from the surface. Downhole tools include an insert disposed within a recess in a body, and the insert comprises an anti-balling material having a composition selected to reduce accumulation of formation cuttings on the tools when the tools are used to form or service a wellbore. Downhole tools include anti-balling material disposed over a porous mass provided over the surfaces of the tools. Methods of forming downhole tools include providing anti-balling material over features on and/or in a surface of a body of a tool. Methods of repairing downhole tools include removing an insert therefrom and disposing a replacement insert therein.Type: GrantFiled: December 27, 2016Date of Patent: July 17, 2018Assignee: Baker Hughes IncorporatedInventors: Suresh G.

Patent number: 9027650Abstract: An apparatus for use downhole is disclosed. The apparatus includes a downhole device and an actuation device that includes: a housing including an annular chamber configured to house a first fluid therein and a piston in the annular chamber that divides the annular chamber into a first section and a second section. The piston is to a biasing member. A control unit enables movement of the first fluid from the first section to the second section to supply a second fluid under pressure to the tool to move the tool into an active position and from the second section to the first section to stop the supply of the second fluid to the tool to cause the tool to move into an inactive position.Type: GrantFiled: August 25, 2011Date of Patent: May 12, 2015Assignee: Baker Hughes IncorporatedInventors: Steven R.
