    Abstract: Method of operating earth-boring tools may involve activating a selectively activatable hydraulic fracturing device secured to the earth-boring tool to impact an underlying earth formation with a fluid from the selectively activatable hydraulic fracturing device. A crack may be at least one of initiated or propagated in a portion of the underlying earth formation utilizing the fluid in response to activation of the selectively activatable hydraulic fracturing device. The selectively activatable hydraulic fracturing device may be subsequently deactivated. Earth-boring tools may include a selectively activatable hydraulic fracturing device configured to transition between an activated state in which fluid is permitted to flow through the selectively activatable hydraulic fracturing device to engage with an underlying earth formation and a deactivated state in which fluid does not flow through the selectively activatable hydraulic fracturing device. The selectively activatable hydraulic fracturing device may be configured to at least one of initiate or propagate cracks.

    Abstract: Methods of forming earth-boring tools include using a plasma spray device to gouge at least one recess through a hardfacing material and into a body. At least a portion of the recess may define a cutting element pocket in which a cutting element may be received and bonded. The recess formed using the plasma spray device optionally may be further machined to form the cutting element pocket. Earth-boring tools are fabricated using such methods.

    Abstract: An earth-boring tool includes a tool body, at least one cutting element, and a retaining member comprising a shape memory material (e.g., alloy, polymer, etc.) located between a surface of the tool body and a surface of the cutting element. The shape memory material is configured to transform, responsive to application of a stimulus, from a first solid phase to a second solid phase. The retaining member comprises the shape memory material in the second solid phase, and at least partially retains the at least one cutting element adjacent the tool body. The shape memory material may be trained in a first phase to a first shape, and trained in a second phase to a second shape. The retaining member may be at least partially within a cavity in the first phase, then transformed to the second phase to apply a force securing the cutting element to the tool body.

    Abstract: Methods of operating earth-boring tools may involve extending a selectively actuatable cutting element outward from a face of the earth-boring tool. A portion of an underlying earth formation may be crushed by a crushing cutting action utilizing the selectively actuatable cutting element in response to extension of the cutting element. The selectively actuatable cutting element may subsequently be retracted. Earth-boring tools may include a selectively actuatable cutting element mounted to a blade, the selectively actuatable cutting element configured to move between a retracted state in which the selectively actuatable cutting element does not engage with an underlying earth formation and an extended state in which the selectively actuatable cutting element engages with the underlying earth formation. The selectively actuatable cutting element may be configured to perform a gouging or crushing cutting action at least upon initial positioning into the extended state.

    Abstract: Wellbore sensor systems and related methods are disclosed. A wellbore sensor system includes a first sensor node and a second sensor node. The first sensor node is operably coupled to a drill string at a first location. The second sensor node is operably coupled to the drill string at a second location. A method includes taking first sensor readings from the first sensor node relative to a first spatial frame of reference, and taking second sensor readings from the second sensor node relative to a second spatial frame of reference, and using the first sensor readings and the second sensor readings to estimate parameters of a mathematical transform configured to transform the second sensor readings into the first spatial frame of reference. The method also includes transforming the second sensor readings into the first spatial frame of reference with the estimated mathematical transform.
