A fluid density valve housing includes a pilot fluid inlet and outlet and a primary fluid inlet and outlet. A shuttle is disposed within the housing. The shuttle comprises a portion having a reference density and a portion defining a cavity fluidically connected to the pilot fluid inlet, the shuttle permitting or denying primary fluid flow depending upon a density of a pilot fluid flowing through the cavity versus the reference density. A method for controlling flow, including comparing density of a pilot flow with a reference density, moving a valve between fully open, fully closed, and choked depending upon the differential density between the pilot fluid and the reference density. A borehole system, including a borehole in a subsurface formation, a string in the borehole, and a fluid density valve disposed within or as a part of the string.

An embodiment of a downhole device includes an elongated body configured to be deployed in a borehole in an earth formation, the borehole including a borehole fluid. The device also includes a propulsion system attached to the body and configured to move the device through the borehole. The propulsion system includes one or more rotor blades configured to generate thrust using the borehole fluid. At least part of the one or more rotor blades is disposed external to the elongated body.

Element

A system includes a tubular having an interior surface, a longitudinal axis, a flowbore, and a main portion having a first inner diameter. A vibration inducing feature is disposed along the interior surface of the tubular and is immovable with respect to the tubular, and has a second inner diameter within the tubular that is different than the first inner diameter. The feature has a beveled first end surface and a beveled second end surface, the beveled first and second end surfaces longitudinally displaced from each other. The feature is configured to increase turbulence within the flowbore and configured to dissuade a capture of objects passing therethrough. A sensing system includes a sensor arranged to detect vibration within flow passing the vibration inducing feature, and is configured to output a command signal in response to sensed data reaching a threshold value or indicative of a predetermined pattern.

A valve assembly for a plug to close off a zone in the well for further treatment above the plug features a valve member initially pinned in an open position where flow up to a predetermined level can move through without dislodging the valve plug to move to its associated seat. If the perforating gun misfires a replacement gun can be run in with flow as the plug is still retained in the position for flow through the plug. On the other hand flow around the plug above a predetermined level will shear retainers for the plug and let the plug land on its seat closing flow in a downhole direction for treatment.

Flow activated valve

A flow device includes a flow-through region comprising at least one stage having a pocket configured to create a first pressure drop across the flow-through region in response to flow through the flow-through region in a first direction and a second pressure drop in response to flow through the flow-through region in a second direction. The first pressure drop is less than the second pressure drop under the same flow rates. The flow device has no moving parts to create the difference in pressure drop between the first direction and the second direction, the pocket has a larger cross sectional flow area than a first opening and a second opening fluidically connected to the pocket and a baffle positioned within the pocket having a 'U' shape with a concave side of the baffle facing toward the second opening.

Activation devices operable based on oil-water content in formation fluids

A subterranean debris catcher swirls the incoming debris laden stream by putting grooves or spiral projections on the inside of the inlet pipe. The solids come out of openings in the side of the inlet pipe or the solids can exit near the top either directly into the enclosed solids holding volume as the liquid exits straight out or the solids can be discharged out the end of the inlet pipe into the bigger open space defined by the housing. In the latter case the inside housing wall can have a screen or vanes that slow down the solid particles as the fluid continues to a housing exit and eventually to an exit screen before being discharged to either go to the surface or recirculate back along the outside of the tool to the inlet pipe while picking up additional debris.

A circulation sub is provided that has a ball seat and a circulation port that is closed when a ball is landed on the seat. An axial passage directs the pressure surge created with the landing of the ball on the seat to the port with the actuation piston for the tool. The surge in pressure operates the actuation piston to set the tool, which is preferably a packer. Raising the circulation rate through a constriction in a circulation sub breaks a shear device and allows the restriction to shift to cover a circulation port. The pressure surge that ensues continues through the restriction to the actuating piston for the tool to set the tool.
