    摘要: A method and system of subsea intervention comprises lowering one or more assemblies of intervention equipment into the sea. Underwater marine units (such as remote operated vehicles or small submarines) may be employed to connect the assemblies to each other and to the subsea wellhead equipment. The subsea wellhead equipment includes a carrier line spool (e.g., coiled tubing spool, wireline spool, slickline spool) and equipment to inject a carrier line from the carrier line spool into the subsea well. The carrier line spool can be located underwater, such as on the sea floor or positioned above the subsea wellhead equipment. The carrier line spool can also be located on a sea vessel. Also, to switch tools, a carousel system having multiple chambers containing different types of tools can be used.

    摘要: A perforating gun contains charges which are rotatable between a stored position and a deployed position, the charges being connected to an enclosed carrier tube via a mechanical link retaining apparatus which is capable of bending but is incapable of stretching by any substantial distance. A primacord is held by said retaining apparatus firmly onto a top of each charge thereby preventing relative movement between the primacord and the charge when the charge is deploying between its stored position and its deployed position. A set of pullrods connect to each pivot of each charge. Thus, when an upward force is placed on the pullrods, an accompanying force is placed on the pivots of each charge. Since the retaining apparatus connects to the top of each charge and to the carrier, and since the retaining apparatus is incapable of stretching by any substantial distance, the accompanying force on the charge pivots creates a torque which rotates the charges between the stored position and the deployed position.

    摘要: Methods include introducing a casing into a wellbore penetrating a subterranean formation, the casing forming an annulus with the wellbore surface, where the casing is subject to a first pressure value at a distal end and a second pressure value at a proximal region within the casing, and where a shoe is positioned at the distal end of the casing. Then, placing a sealable valve within the proximal region of the casing, injecting a first cement composition into the casing, through the sealable valve and shoe, and into the annulus, and the placing a second cement composition in a medial region of the tubular formed between the distal end and the proximal region. Afterward, the sealable valve is closed.

    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: An actuating method includes applying an input pressure to a first side of a tool operator and to a second side of the tool operator and moving the tool operator from a first position to a second position in response to depleting the input pressure applied to the second side. A state of a tool element can be changed in response to moving the tool operator from the first position to the second position. The input pressure may be depleted from the second side of the tool operator by transferring hydraulic fluid to a confined diameter container disposed in an annular region of the actuating device or to the first side of the tool operator.

    摘要: A passive liquid flow monitoring system includes a monitoring device made of a liquid-soluble material in which coded transponders are releasably retained. The monitoring device may be deployed proximate a region of interest in a hydrocarbon-producing well. Characteristics of a liquid flow in the region of interest may be determined based upon detection of transponders that are released from the monitoring device when the monitoring device is exposed to the liquid flow.

    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.
