Abstract: In one aspect, a rotary union for a wheel end system including a wheel hub having a passageway. The rotary union includes a pressurized air receiver configured to be mounted to a vehicle spindle, an air inlet of the pressurized air receiver, a pressurized air distributor rotatable around an axis relative to the pressurized air receiver, and an air outlet of the pressurized air distributor. The pressurized air distributor is configured to be mounted to the wheel hub and rotate therewith. The rotary union further includes a seal axially spaced from the air inlet so that the seal and the air inlet are offset from one another along with the vehicle spindle. The seal is shiftable from a disengaged configuration to an engaged configuration to permit pressurized air received at the air inlet of the pressurized air receiver to flow to the air outlet of the pressurized air distributor.

Abstract: In one aspect of the present disclosure, a wheel hub is provided that includes a wheel hub body having an inboard end and an outboard end. The wheel hub body has a wheel mounting portion, such as a flange, intermediate the inboard and outboard ends. The wheel hub body has a central opening, an interior surface extending about the central opening, and an exterior surface opposite the interior surface. The wheel hub includes a passageway having an interior port at the interior surface of the wheel hub body and an exterior port at the exterior surface of the wheel hub body. The interior port is outboard of the inboard end of the wheel hub body. The exterior port is intermediate the wheel mounting portion and the outboard end of the wheel hub body.

Abstract: A casing removal system includes a flow diversion valve. The flow diversion valve includes a flow switch that engages an upper end of an inner casing. When the flow switch engages the upper end of the inner casing, the flow diversion valve opens and at least a portion of the fluid flow through the casing removal system exhausts to the annulus. The remaining fluid flow below the flow diversion valve is insufficient to operate a mud motor that drives a casing cutter. In other embodiments, when the flow switch is not engaged with the inner wall of casing, the flow diversion valve prevents fluid flow to components that are downhole of the valve and when the flow switch is engaged with the inner wall of casing, the flow diversion valve allows for fluid flow to components that are downhole of the valve.

Abstract: A device, such as a valve, includes a hard seat having an axial bore extending along a central axis. A flapper pivotally connected with the hard seat at a hinge axis and pivotal between an open position to allow flow through the bore and a closed position to block flow through the bore, the flapper having a flapper sealing surface that slopes inward toward the central axis along a full circumference of the flapper sealing surface and the hard seat having a hard sealing surface that slopes inward toward the central axis conforming to the flapper sealing surface and on which the flapper sealing surface bears when in the closed position.

Abstract: A device in accordance to an embodiment includes a tubular housing having an inside diameter defining an axial bore, a top surface and an outer surface, a groove formed along the outer surface below the top surface, a flapper pivotally connected with the housing and pivotal between an open position to allow flow through the bore and a closed position to block flow through the bore and a torsion spring having a spring diameter and disposed in the groove and in connection with the flapper to bias the flapper to one of the open and the closed position. The torsion spring may be nested in a C-shaped groove.

Abstract: A shaped charge includes a casing defining an interior volume, wherein the casing is prepared by sintering a metal powder or a mixture of metal powders; a liner located in the interior volume; and an explosive between the liner and the casing. A method for manufacturing a shaped charge casing includes the steps of mixing a metal powder or a metal powder mixture with a binder to form a pre-mix; pressing the pre-mix in a mold to form a casing green body; heating the casing green body to a first temperature to vaporize the binder; raising the temperature to a second temperature in an inert or reducing atmosphere to sinter the metal powder or the metal powder mixture to produce the shaped charge casing.

Abstract: A device, such as a valve, having a soft seat disposed in a groove formed in and circumferentially along a hard seating surface of a hard seat and one or more retaining elements disposed in the groove in contact with the soft seat and the hard seat.

Abstract: An actuation method according to one or more embodiments includes axially translating an operator in a first direction in response to applying a tubing pressure to a first side in excess of an annulus pressure acting on a second side, axially translating the operator in a second direction to an actuation position in response to applying an underbalance pressure level to the operator and operating a tool element from a first position to a second position in response to translating the operator to the actuation position.

Abstract: A shifting tool having a release mechanism of predictable deforming radial character. The tool may be utilized for activating any of a variety of different types of downhole actuators. Once more, due to the controlled and predictable manner of deformation employed in the release mechanism, load pulls directed at the actuator may be significant without undue concern over unintended or uncontrolled tool breakage. So, for example, a stuck actuator arm engaged with the shifting tool may be safely pulled at substantially greater loads thereby increasing the odds of dislodging. Thus, the occurrences of added follow-on interventional applications addressing stuck actuator arms may be reduced, resulting in tremendous time and cost savings.

Abstract: An actuator that may be used in a wellbore to change the state of a downhole tool. The actuator has an operator that is axially movable in response to changes in tubing pressure. The actuator includes a hydraulic circuit that creates a temporary reference pressure against which the tubing pressure indexes the operator.

Abstract: Pressure cycle independent indexer devices and methods include an indexing logic having a trigger sequence path defining a pressure event (e.g., one or more pressure events) between a starting slot and an actuation slot and each pressure event being located between a sequence transition point from an incoming sequence leg into an outgoing sequence leg of the trigger sequence path and a return transition point from the trigger sequence path into a return path. The indexing logic may permit cycling hydraulic pressures in a well without inadvertently cycling through the trigger sequence path.
