    摘要: An electro-hydraulic actuator includes a housing having an interior portion a first opening and a second opening, a transducer is arranged in the interior portion. The transducer includes a sensor operatively coupled to a signal source at the first opening. A selectively activatable valve component is arranged at the second opening. The selectively activatable valve component maintains a desired pressure in the interior portion of the housing. An actuator is operatively coupled to the transducer and operable to activate the selectively activatable valve component exposing the interior portion to a volume of fluid in response to a signal from the transducer to activate a downhole system.

    摘要: An object including a housing, a cone movably received in the housing, a piston body attached to the cone, a valve disposed as a part of the object and separating hydrostatic pressure from pressure at an interface between the housing and the piston body, and a trigger configured to open the valve at a selected circumstance. A method for moving a selected downhole tool including running an object into a borehole, counting features in the borehole using a sensor in the object, opening the valve at a selected count, flooding the interface with hydrostatic pressure, driving the piston body away from the housing, and moving a radially expandable shoulder member toward a larger diameter end of the cone. A borehole system including a borehole in a subsurface formation, a string disposed in the borehole, and an object disposed within or as a part of the string.

    摘要: A frac dart including an electric counter in the frac dart, an inductor in the frac dart, in electrical communication with the counter, the inductor generating a voltage responsive to the dart moving through a magnetic field. A method for selectively landing a dart on a landing feature in a well including sensing a landing feature by generating an inductor signal with an inductor pursuant to the inductor passing through a magnetic field associated with the landing feature in the well. generating a count in an electrical counter of the dart responsive to the inductor signal, applying a count signal to a switch of the dart based upon the count, selectively passing the count signal to an activator or an actuator of the dart based upon switch position.

    摘要: A screen connection area assembly configured to mount between adjacent sand screens of a gravel pack string including a body attachable to a screen connection area between two adjacent sand screens of the gravel pack string, the body configured to displace fluid and present a radial dimension between about 75% and 100% of a radial dimension of the adjacent sand screens. A method for packing a gravel pack string including disposing an assembly as in any prior embodiment on a screen connection area between adjacent sand screens of the string, running the string into a borehole, supplying a slurry to the borehole proximate the sand screens, packing the sand screens and the screen connection area between adjacent sand screens without altering a flow regime of the slurry.

    摘要: An embodiment of a fluid control device includes a housing, a fluid channel defined within the housing, the fluid channel having a first surface and a second surface opposing the first surface and having an inlet, and a flow control body disposed in the fluid channel, the flow control body tapering toward the inlet. The body, in use, causing fluid flowing through the channel to diverge into at least a first path between the first surface and a first side of the body, and a second path defined by at least by the second side of the body. A geometry of the first path and the second path selected is based on a subcool of the fluid at a pressure of the fluid entering the fluid channel, and the geometry is selected to induce cavitation of the fluid to choke fluid flow through the fluid channel.
