    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: 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: 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: 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.

    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: 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.
