    摘要: Casing bits include an expander for enlarging an inner diameter of expandable casing at least partially disposed within a body of the casing bits. Drilling assemblies include a casing bit attached to an end of expandable casing, and an expander disposed in proximity to the casing bit and a distal end of the expandable casing. Methods of forming casing bits include positioning an expander in proximity to a body of a casing bit. Methods of forming drilling assemblies include positioning an expander in proximity to a body of a casing bit and a distal end of expandable casing, and attaching the casing bit to the end of the expandable casing. Methods of casing a wellbore include one or both of drilling and reaming a wellbore using a casing bit attached to a distal end of expandable casing, and forcing an expander through the expandable casing.

    摘要: Downhole tools are provided with a topographical pattern, and anti-balling material is provided 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.

    摘要: Earth-boring tools comprise a body and one or more replaceable cutting structures attached to the body at a face region of the body. Each replaceable cutting structure comprises an attachment member and a cutting portion configured to engage an underlying earth formation. Methods of forming an earth-boring tool comprise attaching one or more cutting elements to a replaceable cutting structure; positioning the replaceable cutting structure proximate a region of a body of an earth-boring tool that is susceptible to at least one of localized wear and localized impact damage; and attaching the replaceable cutting structure to the body. Methods of repairing an earth-boring tool comprise bringing a replaceable cutting structure proximate at least one portion of a body of an earth-boring tool exhibiting at least one of localized wear and localized impact damage; and attaching the replaceable cutting structure to the earth-boring tool at the at least one portion.

    摘要: An expandable reamer apparatus for drilling a subterranean formation may include a tubular body, one or more blades, each blade positionally coupled to a sloped track of the tubular body, a push sleeve and a drilling fluid flow path extending through an inner bore of the tubular body for conducting drilling fluid therethrough. Each of the one or more blades may be configured to ream a subterranean formation. The push sleeve may be disposed in the inner bore of the tubular body and coupled to each of the one or more blades so as effect axial movement thereof along the track to an extended position responsive to exposure to a force or pressure of drilling fluid in the flow path of the inner bore. Each blade may include one or more roller elements for reaming a wellbore.
