摘要： An axial position-controlled operation toolstring for conducting an axial position-controlled operation in a well includes from below and up: a casing cutter tool including knives; a tag sub with dogs arranged for landing on a protrusion in said well; a pipe spear; and a drill pipe string. The knives of the casing cutter tool are spaced out a predetermined initial distance below the dogs of the tag sub. The dogs are arranged for being collapsible by weight loading against the protrusion. A method includes using the toolstring.

摘要： A side pocket mandrel for use in a gas lift system includes a primary flow bore that is linearly aligned with the primary longitudinal axis of the production tubing. The side pocket mandrel also includes valve pocket that is laterally offset from the primary flow bore, where the valve pocket includes a port that extends through the side pocket mandrel to the annular space (annulus) to place the interior of the valve pocket in fluid communication with the annulus. To prevent the unintended passage of fluids from the interior of the side pocket mandrel to the annulus through the valve pocket and port, the side pocket mandrel includes an integrated check valve within the port that permits the flow of fluids from the annuls into the side pocket mandrel, while preventing the passage of fluids from the side pocket mandrel to the annulus.

摘要： Provided is a method for deploying a multi-zone completion assembly, as well as a downhole tool and a well system. In one aspect, the method for deploying the multi-zone completion assembly includes coupling a casing scraper assembly to an inner service tool string hanging from a beginning section of a packer assembly suspended from a rig floor, the inner service tool string located within and extending below the beginning section of the packer assembly, and the casing scraper assembly located entirely below the beginning section of the packer assembly string. In one or more other aspects, the method includes completing the packer assembly string from the rig floor as the inner service tool string and casing scraper assembly are hanging therefrom.

摘要： A kickover tool for retrieving a used gas lift valve installed within a gas lift mandrel connected along a wellbore tubular string and installing a new gas lift valve within the gas lift mandrel. The kickover tool may include a housing, a first holder configured to hold the used gas lift valve, a first displacement mechanism operable to move the first holder between a retracted first holder position in which the first holder is adjacent the housing and an extended first holder position in which the first holder is spaced away from the housing, a second holder configured to hold the new gas lift valve, and a second displacement mechanism operable to move the second holder between a retracted second holder position in which the second holder is adjacent the housing and an extended second holder position in which the second holder is spaced away from the housing.

摘要： Apparatuses and methods for positioning a flexible hose into a wellbore with a protective housing are disclosed. A flexible hose is contained within a protective housing and both are positioned into a wellbore to a desired depth. Pressure can be applied to an interior of the protective housing, and a packoff seals between the flexible hose and the protective housing, causing the pressure to eject the hose from the protective housing.

摘要： Methods and systems are provided for dislodging a ferromagnetic disk removably installed in a wellbore. The disk can be installed in the wellbore during oil and gas well completion and production activities to maintain pressure within the wellbore. More specifically, the disclosure relates to using a strong magnet installed within a magnetic tool to dislodge and remove a ferromagnetic disk without breaking the disk. The strong magnet can be a neodymium magnet, electromagnet, or other types of strong magnets.

摘要： Apparatus for gaining access to a well via a lateral access passage includes a flexible conduit which is to be inserted into the well via the lateral access passage so as to deviate from a direction of lateral insertion to a generally downward direction down the well. The flexible conduit includes a probe at a front end thereof. The probe includes a spring at least 0.5 m in length. A probe container is provided for accommodating the probe before it is inserted into the well. A guide may be provided for insertion along the lateral access passage and for assisting deviation of the flexible conduit from the direction of lateral insertion.
