A poppet valve having an elongated tubular housing and an internal bore. A flange extends within the internal bore supporting an interior tubular member. The interior tubular member itself has a central aperture and an inwardly protruding lip extending into the central aperture. A stem having collet fingers may be partially received in the central aperture of the interior tubular member. The collet fingers have a protrusion which is engagable with the inwardly protruding lip. A biasing element is provided biasing the stem toward a first position. An elastomeric seal may be disposed around the stem. When the stem is in a first position the elastomeric seal forms a fluid tight seal preventing fluid flow through the internal bore, and wherein upon application of a predetermined fluid pressure the stem transitions from the first position to a second position, whereby fluid flow is permitted through the internal bore.

Disclosed are systems of positional tracking of a downhole projectile using a downhole monitoring tool. One downhole monitoring tool includes a body, at least one sensor arranged on the body and configured to detect a wellbore projectile, an indicator chamber defined in the body and configured to retain an indicator substance, and an actuation device operatively coupled to the indicator chamber and in communication with the at least one sensor, wherein, when the at least one sensor detects the wellbore projectile, a command signal is sent to the actuation device to actuate the indicator chamber and thereby release at least a portion of the indicator substance through an ejection port.

Tracking the position of a downhole projectile

A float valve assembly includes a cylindrical housing defining an inner flow path and a check valve is positioned within the housing and movable between an open position, where uphole and downhole fluid flow through the inner flow path is allowed, and a closed position, where uphole fluid flow is prevented while downhole fluid flow is allowed. An activation member is movably positioned within the housing between a first position, where the activation member holds the check valve in the open position, and a second position, where the activation member moves axially and out of engagement with the check valve. A drag body is coupled to the activation member and fluid flow in the downhole direction generates a drag force on the drag body that places an axial force on the activation member to move the activation member to the second position.

Float valve assembly with drag force dependent deactivation

A float valve can include a selection mechanism having an open configuration in which flow into and out of the valve is permitted, and a closed configuration in which flow out of the valve is permitted and flow into the valve is prevented. The selection mechanism can be actuated from the closed configuration to the open configuration. A method of actuating a float valve can include actuating the valve from a closed configuration in which flow into the valve is prevented but flow out of the valve is permitted, to an open configuration in which flow into and out of the valve is permitted. The valve can actuate from the open configuration to the closed configuration, and from the closed to the open configuration, in response to a flow rate through the valve being greater than a predetermined level.

Float valve with resettable auto-fill

A debris separator device for use with a casing system is provided. The debris separator device may include an impeller having a plurality of blades to generate a vortex of mud in the section of the casing system when the casing system is lowered into a wellbore. The device may also include a baffle disposed in the section of the casing system, the baffle having an annular cup shape that forms an outer circumferential pocket to capture debris from the vortex of mud. The impeller and baffle may enable the debris separator device to separate debris and other debris from a flow of mud through the casing system so that the debris does not clog a float collar of the system. The disclosed debris separator device may be flushable so that the device does not become clogged with debris and can thereby maintain auto-fill through the casing system.
