Abstract: An embodiment of a PCD insert comprises an embodiment of a PCD element joined to a cemented carbide substrate at an interface. The PCD element has internal diamond surfaces defining interstices between them. The PCD element comprises a masked or passivated region and an unmasked or unpassivated region, the unmasked or unpassivated region defining a boundary with the substrate, the boundary being the interface. At least some of the internal diamond surfaces of the masked or passivated region contact a mask or passivation medium, and some or all of the interstices of the masked or passivated region and of the unmasked or unpassivated region are at least partially filled with an infiltrant material.

Abstract: Methods, systems, devices, and products for performing well logging in a borehole intersecting an earth formation to obtain and transmit an acoustic reflection image of the formation. Methods include identifying a set of features in the acoustic reflection image substantially fitting a pattern, wherein the set of features corresponds to a portion of at least one reflecting structural interface of the formation; and using a representation of the pattern as the compressed representation of the acoustic reflection image. The features may be amplitude peaks in the acoustic reflection image, and the pattern may be a line segment therein that is obtained from the amplitude peaks. Identifying the set of features may include generating a binary image of the amplitude peaks.

Abstract: A system including a subsea module, a tool hanger, and an in-well tool string coupled to and extending from a lower portion of the tool hanger is provided. The subsea module includes a subsea spool with a main bore formed therethrough, and the main bore includes a tool hanger interface. The subsea module also includes a connector for mounting the subsea module on a subsea component, wherein the connector includes a grip configured to engage the subsea component, and a first seal coupled to the connector and configured to seal the connector against the subsea component. The tool hanger is disposed within the main bore and coupled to the tool hanger interface via at least a second seal configured to seal the tool hanger against the main bore of the subsea spool. The in-well tool string is configured to couple the tool hanger to an in-well tool.

Abstract: A method of treating a subterranean formation penetrated by a wellbore comprises: introducing into the subterranean formation a treatment fluid comprising a carbonate producing agent, urea, and a cation source; allowing a carbonate precipitate to form, the carbonate precipitate comprising a cation from the cation source and having a water solubility of less than about 0.1 g/100 mL at 25° C. and atmospheric pressure; and reducing or substantially preventing the passage of formation particles from the subterranean formation into the wellbore while allowing passage of formation fluids from the subterranean formation into the wellbore.

Abstract: A system and method for logging in a wellbore where sensor assemblies on a logging tool are deployed and landed in the wellbore. After the sensor assemblies are landed in the wellbore and released from the logging tool, the logging tool is pulled uphole. Moving the logging tool uphole from where the sensor assemblies are landed, reduces interference of the logging tool with measurements obtained with the sensor assemblies. The sensor assemblies include sensors for detecting fluid flow, pressure, temperature, fluid density, formation resistivity, and which can be mechanical, optical, acoustic, or electromagnetic.

Abstract: Activation modules for selectively sealing entrances to inner barrels of coring tools may include an activator body and an activation rod movable between a first position and a second position. A locking element may temporarily hold the activator body in place and a sealing element may form a temporary seal. The activation rod may include a locking portion, a releasing portion of a smaller diameter, a sealing portion, and an unsealing portion of a smaller diameter. The locking portion may be aligned with the locking element and the sealing portion may be aligned with the sealing element when the activation rod is in the first position. The releasing portion may be aligned with the locking element and the unsealing portion may be aligned with the sealing element when the activation rod is in the second position.

Abstract: Systems and methods for controlling downhole linear motors to minimize connections to surface equipment. In one embodiment, an ESP system is coupled by a power cable to equipment at the surface of a well. The ESP system includes a linear motor and a reciprocating pump. The motor has a set of position sensors that sense the position of a mover in the motor. Combining circuitry (E.G., XOR gate) combines the outputs of the position sensors into a single composite signal in which signal components corresponding to the position sensors are indistinguishable. A single channel carries the composite signal from the ESP system to the surface equipment. A control system determines a starting position of the motor and determines its subsequent position based on transitions in the composite signal. The motor is then operated based on the position determined from the composite signal.

Abstract: Systems and methods for reducing vibration in an electric motor using rotor bearing assemblies that are positioned within a bore of the stator to support the motor's shaft and rotor sections so that they can rotate within the stator bore. Each rotor bearing assembly includes an outer bearing and an inner bearing sleeve that rotates within the bearing. The bearing is secured so that its rotation within the stator is inhibited, but it can move axially. Each end of the bearing sleeve has a conically tapered contact surface which contacts and secures the corresponding rotor section and centers the rotor section with respect to the axis of rotation of the bearing. The contact surfaces of the rotor sections may be chamfered at an angle complementary to the tapered contact surface of the bearing sleeve to distribute the contact pressure between them over a greater contact surface area.

Abstract: Methods of evaluating prototype cutting elements for earth-boring tools may involve generating first and second sets of virtual representations of cutting elements from first and second sets of used cutting elements. First and second sets of measures of damage corresponding to damage for each of the first and second sets set of virtual representations of cutting elements may be determined. A best-performing set of cutting elements from the first and second sets of used cutting elements according to the first and second sets of measures of damage may be identified by performing a statistical analysis.

Abstract: Methods of using a component in a subterranean wellbore include positioning a component including a degradable thermoset polymer material in a wellbore location, obstructing flow with the component, exposing the component to an acidic solution to degrade the selectively degradable thermoset polymer material and to remove the component from the wellbore location, and flowing a fluid through the wellbore location where the component was positioned. Methods of forming a component of a wellbore system include forming at least a portion of the component to comprise a degradable thermoset polymer material. Wellbore systems include at least one component including a selectively degradable thermoset polymer material. The selectively degradable thermoset polymer material may be a polyhexahydrotriazine (“PHT”) material.
