    摘要: A technique facilitates generation of electric power in well environments. The technique involves combining a cooperating stator and rotor assembly to create an electromagnetic generator. The cooperating stator and rotor assembly utilize an electromagnet which works with a generator coil to create electrical power. Use of the electromagnet enables the electromagnetic field created during generation of electrical power to be selectively eliminated. Elimination of the electromagnetic field allows magnetic particles to be freely flushed from the electromagnetic generator.

    摘要: Well operating elements are described, one embodiment comprising a first component that is substantially non-dissolvable when exposed to a selected wellbore environment and a second component that 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. A second embodiment includes the component that is soluble in the selected wellbore environment, and one or more exposure holes or passages in the soluble component to control its solubility. The second embodiment may or may not include a substantially non-dissolvable component. Methods of using the well operating elements in oilfield operations are also described. 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.

    摘要: An apparatus and method for plugging a wellbore completion. The apparatus includes a body and a variable diameter ring. The body includes a first portion having a first diameter, and a second portion having a second diameter that is smaller than the first diameter. The variable diameter ring is disposed around the body and slidable on the first and second portions. The ring is configured to engage a flow path reduction device when located on the first portion, and to move past the flow path reduction device when located on the second portion.

    摘要: An apparatus that is usable with a well includes an operator and a generator. The operator is disposed in the well and configured to respond to a differential pressure between hydraulically isolated zones of the well to produce mechanical motion. The generator is disposed in the well to convert the mechanical motion into electricity. A method that is usable with a well is provided including maintaining hydraulic isolation between a first and second zone of a well. While maintaining the hydraulic isolation, the method further includes producing a mechanical motion in response to a differential pressure between the first and second zones and generating electricity in response to the mechanical motion.

    摘要: A technique is provided that utilizes one or both of a control line actuation mechanism and a connector protection mechanism for use in a wellbore environment. Upon landing a lower well assembly and an upper well assembly at a desired wellbore location, control line connectors are engaged. The control line actuation mechanism and/or connector protection mechanism facilitate the formation of a desirable control line connection.

    摘要: Well surface equipment is provided to seal around the outer surface of portions of tool sections as the tool sections are assembled or disconnected in a portion of the well surface equipment. The portion of the well surface equipment is isolated from wellhead pressure to enhance well operator control during assembly or disassembly of a tool string. Also, if a fluid path is opened up due to activation of the tool string (such as initiation of a detonating cord that is placed in the fluid path), a barrier mechanism is actuated to block fluid communication through this fluid path so that a portion of the well surface equipment can remain isolated from wellhead pressure to enable convenient retrieval and disconnection of tool sections.
