    摘要: 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. A valve assembly is disposed within the tubular body and configured to control the flow of the drilling fluid into an annular chamber in communication with the push sleeve; the valve assembly comprising a mechanically operated valve and/or an electronically operated valve. Other embodiments, including methods of operation, are provided.

    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: Walk characteristics of an earth-boring rotary drill bit may be predicted by measuring locations and orientations of cutting elements thereof and calculating the magnitude and direction of an imbalance force of the drill bit using the measurements obtained. The calculated imbalance force may be compared to the imbalance force of at least one other drill bit having a calculated imbalance force and observed walk characteristics. An earth-boring rotary drill bit may be designed by constructing a database including the magnitude and direction of a calculated imbalance force and observed walk characteristics for a number of drill bits. Desired walk characteristics are selected, the database is referenced, and the bit may be configured to exhibit an imbalance force selected to impart desired walk characteristics to the drill bit. Drill bits are configured to exhibit an imbalance force oriented in a predetermined direction relative to a blade of the drill bit. A system may be employed to monitor the imbalance force of an operating drill bit and to provide or implement desirable operational parameters to compensate for same.
