    Abstract: Described herein are embodiments of systems and apparatuses that include a dart and/or a clutch for a dart plunger. In an exemplary embodiment, the clutch consists of a one-piece unit having a length, an outside diameter, and an inside diameter where at least a portion of the inside diameter is sized to create a frictional interface with a dart. The clutch may also include a gap, a slot, and/or a spiral cut. The dart may include a shaft having opposite ends and a shaft diameter that varies between the opposite ends.

    Abstract: A body of a shear pin can be positioned in a pad stopper of a steering pad of a rotary steerable system. The rotary steerable system can be used to steer a drill in a wellbore. The steering pad can be positioned on the rotary steerable system such that a head of the shear pin is coupled with a lateral pad of the rotary steerable system. The head of the shear pin can deactivate the steering pad by preventing the steering pad from actuating. A fluid pulse can be output in the wellbore to break the shear pin for enabling the steering pad to actuate to cause the rotary steerable system to steer the drill in the wellbore.

    Abstract: A rotary steerable drilling system can be positioned in a subterranean formation to steer a drill to form a wellbore in the subterranean formation. An orientation of a steering valve, which is positioned in the rotary steerable drilling system, can be adjusted to cover each channel of one or more channels of a valve seat adjacent the steering valve to deactivate each steering pad of one or more steering pads of the rotary steerable drilling system. The orientation of the steering valve can be adjusted to activate at least one steering pad of the one or more steering pads of the rotary steerable drilling system.

    Abstract: Provided is a float for use with a fluid flow control device, a fluid flow control device, a method for manufacturing a float, and a well system. The float, in one aspect, includes a fluid tight enclosure. The float, according to this aspect, further includes density specific material located within the fluid tight enclosure, the fluid tight enclosure and the density specific material creating a net density for the float that is between a first density of a desired fluid and a second density of an undesired fluid, such that the float may control fluid flow through a flow control device when encountering the desired fluid or the undesired fluid.

    Abstract: A downhole tool includes a body defining a bore axially therethrough and a port in communication with the bore and extending radially through the body, an inner cap positioned in the port, the inner cap sealing the port, and an outer cap positioned in the port. The outer cap is spaced apart from the inner cap, and the outer cap seals the port, such that a chamber is defined between the inner and outer caps in the port. The inner cap is configured to move toward outer cap in response to a first pressure differential between bore and the chamber across the outer cap. The inner cap is configured to dislodge the outer cap from the port in response to the inner cap engaging the outer cap and a second pressure differential between the bore and an exterior of the downhole tool being reached across the inner cap.
