Abstract: An apparatus includes a string that extends into a well and a tool that is disposed in the string. The tool is adapted to form a seat to catch an object communicated to the tool via a passageway of the string in response to the tool being perforated.

Abstract: A technique facilitates mechanical operation of components, e.g. valves, without utilizing electronics at the components or control lines routed to the components. An actuation control system is fully mechanical in the sense that it is constructed to mechanically shift to different control positions via pressure input, such as pressure input supplied along a wellbore annulus. The actuation control system utilizes a spool valve coupled with a pilot control circuit which establishes a reference pressure that can be used in shifting the spool valve to different operational positions.

Abstract: An apparatus that is usable with a well includes a body, a blocking member, a sensor, a radially expandable element and a controller. The body includes a longitudinal passageway that extends through the body, and the blocking member is disposed in the passageway to check fluid from flowing in a predefined direction through the passageway. The sensor is disposed on the body to sense a property of an environment of the string as the object is being communicated through the passageway; the radially expandable element is disposed on the body; and the controller is disposed on the body to selectively autonomously control the expandable element to land the body in a downhole restriction in response to the sensing.

Abstract: In-riser power generation devices and methods are utilized to generate power subsea to operate subsea devices of a subsea well system. A turbine power generator is located in fluid communication with a subsea fluid flow path of a subsea well system and the turbine power generator is operationally connected to a subsea power device.

Abstract: A system for use in a well includes a completion system having a shoulder contact region, an electric submersible pumping system deployed downhole via a cable for landing on the completion system, a tubular member coupled to the electric submersible pumping system and extending downhole from the electric submersible pumping system, and a shoulder mechanism slidably mounted on the tubular member for engagement with the shoulder contact region during landing, the shoulder mechanism being selectively settable along the tubular member to counter tensile loading in the cable. The shoulder mechanism is set against the tubular member via anchors actuated against the tubular member, and the anchors are actuated by a piston movably mounted within a housing of the shoulder mechanism.

Abstract: Well operating elements and related methods are described. One embodiment may take the form of a method that includes deploying a well operating element having first and second components into a well bore, wherein the second component is soluble in the selected wellbore environment and whose rate and/or location of dissolution is at least partially controlled by structure of the first component. This abstract allows a searcher or other reader to quickly ascertain the subject matter of the disclosure. It will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).

Abstract: A technique facilitates control over flow of hydraulic actuating fluid used to perform a plurality of actuating functions in a subsea well application. A control module is employed for controlling a plurality of hydraulically controlled components and is located along a subsea test tree at a position relatively close to the hydraulically controlled components. The control module, in turn, is controlled electronically via an electric line which provides electric control signals corresponding to desired control instructions regarding the hydraulically controlled components. By moving the control module closer to the hydraulically controlled components response time is greatly reduced.

Abstract: A technique facilitates placement and operation of a pumping system in a borehole. The pumping system is deployed downhole into the borehole via a conveyance and landed on a completion system disposed in the borehole. The pumping system is combined with a tubular member and a shoulder mechanism slidably mounted along the tubular member. The shoulder mechanism may be selectively set and locked to the tubular member. When the pumping system is deployed downhole, the shoulder mechanism is allowed to move along the tubular member after engaging a corresponding shoulder contact region of the completion system. Once the pumping system is properly deployed, the shoulder mechanism may be set against the tubular member to support the submersible pumping system and to counter axial loading during testing and/or operation of the submersible pumping system.

Abstract: A method for pressurizing a hydraulic accumulator includes creating an annulus pressure zone in hydraulic communication with the hydraulic accumulator through a hydraulic recharging circuit and applying a hydraulic pressure to the annulus pressure zone. Operating the hydraulic recharging circuit in response to applying the hydraulic pressure and pressurizing the hydraulic accumulator in response to operating the hydraulic recharging circuit.

Abstract: A technique facilitates automatic shut-in of a well and disconnect of a corresponding landing string. The landing string is employed in a well application and comprises a landing string module which measures a parameter or a variety of parameters. Those parameters may be used to determine the occurrence of an event which initiates shut-in of the well and disconnect of the landing string. The subsea landing string system is constructed to enable autonomous shut-in and disconnect.

Abstract: A completions assembly having an autonomous self-sustaining portion powered by an atomic battery. The atomic battery may be of a non-based beta voltaic variety configured to provide uninterrupted power to the autonomous portion of the assembly for substantially the life of the well. Thus, continuous monitoring of well conditions or low power actuations, via sensors and/or actuators of the autonomous portion, may be supported. As a result, the autonomous portion may be operated in a fully wireless manner without the requirement of hard wiring to the main bore/surface connected portion of the completions assembly.
