Abstract: An earth-boring tool includes a shank. The shank may include a central bore extending partially through the shank. An end-cap may be disposed within the central bore, and the end-cap may include a first flange, a second flange, and a body portion extending between the first flange and the second flange. An annular chamber may be defined between the body portion of the end-cap and an interior wall of the central bore of the shank. At least one strain gauge may be secured to an outer surface of the body portion of the end-cap. At least one stain gauge may be secured to a cap portion welded over a recess formed in the earth-boring tool.

Abstract: A pump for use with fluids having particulates has an inlet to allow the fluids into a chamber of the pump. The chamber has a direct flow path of at least one larger width than a side flow path, and has a movable blade and diffuser stack within the chamber. Power features of the pump cause the movable blade to impart a centrifugal force on the fluids within the chamber, while at least one protrusion located circumferentially with respect to the chamber causes the particulates of a direct flow path to gather or causes the particulates to divert from a direction associated with at least one cavity of the chamber.

Abstract: A method of determining a rate of penetration of a downhole tool. The method comprises introducing a downhole tool including a drill bit configured to drill through a subterranean formation in a wellbore, the downhole tool comprising at least one reader configured to communicate with identification tags using electromagnetic radiation. The method includes advancing the wellbore with the drill bit and placing, with a component of a bottomhole assembly of the downhole tool, a first identification tag at a first location proximate the wellbore and at least a second identification tag at a second location proximate the wellbore and separated from the first location by a distance. An interrogation signal is transmitting from the at least one reader toward a wall of the wellbore and response signals from the identification tags are received by the at least one reader to determine proximity of the identification tags to the reader. A rate of penetration of the downhole tool is determined, using a processor and associated memory, based at least in part on a distance between identification tags and an amount of time between receiving response signals from a first identification tag and at least a second identification tag. Downhole systems for determining a rate of penetration and other methods are also disclosed.

Abstract: An encapsulated lost circulation material includes: a particulate having a core including a compressed shape-memory polymer foam, and a disintegrating agent, the disintegrating agent including at least one of a phase change material or a gas-producing material; and a shell encapsulating the core. A method of reducing lost circulation includes: introducing into a subsurface a wellbore fluid including the encapsulated lost circulation material; heating the disintegrating agent to cause the phase change material to expand, or to cause the gas-producing material to produce a gas, or a combination thereof to break the shell; and releasing the compressed shape-memory polymer foam from the encapsulated lost circulation material; expanding the released shape-memory polymer foam; and filling a void or fracture of the subsurface with the expanded compressed shape-memory polymer foam to reduce fluid loss.

Abstract: A wellbore system includes a slip hanger arranged within a wellbore component, the slip hanger having a mechanical receptacle formed in a face of the slip hanger. The wellbore system also includes an adapter configured to couple to the slip hanger, the adapter having one or more engagement members arranged to engage the mechanical receptacle, wherein the one or more engagement members extend into the mechanical receptacle to secure the slip hanger to the adapter.

Abstract: A method and apparatus for locating respective end regions of wires of an armour layer of a segment of flexible pipe body at a respective desired positions in an end fitting, and apparatus for terminating a segment of flexible pipe body in an end fitting are disclosed. The method comprises providing an annular element radially around an exposed region of an armour layer, of flexible pipe body, that comprises a plurality of wires; locating the annular element against a terminal end of a first collar member disposed radially around the armour layer; bending the wires away from a longitudinal axis of the flexible pipe body against a guiding surface of the annular element, at a predetermined location; urging the annular element away from the first collar member in a first direction; and gripping the wires between an abutment region of the guiding surface and a cooperating abutment surface of a further collar member thereby locating respective end regions of the wires at respective desired positions in an end fitting.

Abstract: A method for measuring the temperature of a submersible pumping system motor includes the steps of obtaining an analog motor temperature signal from a motor temperature sensor, converting the analog motor temperature signal to a digital motor temperature signal using an analog-to-digital converter (ADC), providing the digital motor temperature signal to a processor, determining the absolute value of the digital motor temperature signal with the processor to produce a corrected digital motor temperature signal, and reporting the corrected digital motor temperature signal. The method is designed to correct the measurements made by the motor temperature sensor in the event the motor temperature sensor is connected incorrectly.

Abstract: In at least one embodiment, a valve removal (VR) system for an oilfield equipment includes a VR plug having a first surface and a second surface. The VR system includes a bushing to be removably associated with the first surface. The bushing is to extend, at least partly, beyond the second surface of the VR plug. The bushing is also to contact an inner surface of a valve of the oilfield equipment and to prevent the second surface from contacting the inner surface of the valve. The VR system includes a guiding rod to be associated with the VR plug to support guidance of the VR plug through the valve of the oilfield equipment. The guiding rod is also to be disassociated from the VR plug to support removal of the guiding rod from the valve with the VR plug remaining in the oilfield equipment.

Abstract: Drilling mud is flowed through a valve assembly that is set at a particular open amount, measurements are taken of mud flowrate and a force exerted by the drilling mud onto a portion of the valve assembly, and density of the drilling mud is estimated based on historical data. The historical data is generated by directing multiple flows through the valve assembly, where the flows are at different flowrates, and at each flowrate different drilling muds having different densities are directed through the valve assembly. For each flow the valve assembly is adjusted to different open amounts, and a corresponding force exerted by the flow onto the valve assembly is measured. An example of the valve assembly is a mud pulser with a plug member that engages an orifice opening, a sensor in the pulser measures force exerted by the flow of mud.
