A technique provides a desired control over incremental actuation of hydraulic devices. A hydraulically actuated tool is combined with a control module. The hydraulically actuated tool has an actuator piston positioned in a piston chamber and movable between operating positions. The control module comprises a hydraulic indexing circuit arranged to enable incremental movement of the actuator piston in a first direction and full stroke movement in a second direction based on hydraulic input delivered via control lines. The hydraulic indexing circuit comprises an indexing piston system and at least one check valve working in cooperation with the indexing piston system to enable the incremental and full stroke movements.

A system and method for fracturing multiple zones along a length of a wellbore during a single run are provided. A single magnetic shifter device may be lowered on coiled tubing to shift open multiple sleeve assemblies set along the wellbore to expose different fracture zones for desired fracturing treatments. The sleeve assemblies may each include a magnetic sensing system designed to detect a magnetic field output from the shifter device. The magnetic sensing system may output a control signal to an electro-hydraulic lock to collapse a baffle component of the sleeve assembly. Once the baffle is collapsed, an isolation component of the shifter device may engage the collapsed baffle to form a plug through the wellbore. Pressure applied from the surface may push the baffle and a sliding sleeve of the sleeve assembly downward, thereby exposing fracturing ports through the casing of the wellbore.

A method and apparatus for controlling the flow of fluid in an injection well includes a main valve assembly having a valve and a retrievable nozzle selective lock assembly (RNSLA). The RNSLA is operable when positioned within the valve body to open the valve when fluid is pumped into the well and closes the valve when fluid flow is terminated. The RNSLA includes a replaceable orifice nozzle so that orifices of different dimensions may be used in conjunction with the valve assembly. In an alternate embodiment, the RNSLA includes a variable output nozzle assembly to maintain the valve in a protected open position without chattering over a wide range of flow rates.

Apparatus and methods pertaining to an adapter mechanically connecting a wireless actuator to an SCSSV subassembly that includes an SCSSV. The adapter mechanically connects to the SCSSV subassembly so that the adapter is situated uphole of the SCSSV subassembly when set in a tubular of a wellbore. An actuating piston is carried by the adapter. The actuating piston transfers an opening force to the SCSSV in response to receipt by the adapter of pressurized fluid from the wireless actuator, thereby opening a flapper of the SCSSV.

A valve for use in a wellbore includes a replaceable choke device that is threaded into at least one opening formed through a sidewall of a tubular housing of the valve. The choke device is sealable on the sidewall of the tubular housing with an elastomeric sealing component, and the choke device controls at least one of fluid pressure within the tubular string and a pressure drop across the valve. The valve also includes a flow sleeve carried by the tubular housing for movement relative thereto between a first position in which fluid flow s permitted across the valve, a second position in which the flow sleeve prevents fluid flow across the valve, and a third position in which the flow sleeve is locked in place relative to the tubular housing by a lock ring.

Provided is a communications sub. The communications sub, in one aspect, includes a fluid chamber, and a pressure-activated indexing device positioned within the fluid chamber, the pressure-activated indexing device including a lock mandrel configured to incrementally move between an engaged state and a disengaged state when subjected to two or more pressure cycles. The communications sub, in accordance with one aspect, further includes a latch body positioned in the fluid chamber, the latch body configured to be fixed in place by the lock mandrel and close a fluid path from the fluid chamber to a control line when the lock mandrel is in the engaged state, and configured to be allowed to move and open the fluid path from the fluid chamber to the control line when the lock mandrel is in the disengaged state.

A valve assembly for connection to an opening provided in a housing of a well tool device includes a fluid communication channel, a flapper valve device, a flapper element supporting device, and a securing device. The fluid communication channel provides fluid communication from an outside of the housing to a bore provided on the inside of the housing. The flapper valve device includes a flapper element configured to be in a closed position in which the fluid communication channel is closed and an open position in which the fluid communication channel is open. The flapper element is biased to the closed position. The flapper element supporting device supports the flapper element when the flapper element is in the open position. The securing device secures the flapper valve device and the flapper element supporting device to the opening. The securing device includes a through bore forming a first part of the fluid communication channel.

A toe valve to control the injection of fluid into a toe of an oil or gas well and including: a body with a bore, the body having a port adapted to permit fluid flow between the bore and an outlet on an external surface of the toe valve when the port is open; a closure member adapted to move from an initial closed position in which the port is closed, to an open position in which the port is open; and an actuating mechanism which can be actuated to urge the closure member from the initial closed position toward the open position, and which can be reset when the closure member is moving between the closed and open positions to return the closure member to the initial closed position.

A downhole tool includes a tubular having an outer surface, an inner surface, a recess extending from the inner surface toward the outer surface, and an opening extending from the outer surface to the recess. A hydraulic passage extends through the tubular. The hydraulic passage includes an inlet, a first and a second branch. The second branch is fluidically exposed at the inner surface. A piston is arranged in the recess. A locking ring is arranged radially inwardly of the piston and a member is arranged in the tubular spaced from the inner surface. Application of hydraulic pressure in the first branch urges the piston radially inwardly clamping the locking ring against the member and application of hydraulic pressure in the second branch urges the member axially in a first direction relative to the tubular.
