  • Patent number: 11719076
    Abstract: An apparatus for activating chambers of downhole hydraulic screens. The apparatus comprises an outer sleeve, an inner sleeve, and a flow path. The outer sleeve is coupled to one hydraulic screen on one end and another hydraulic screen on another end. The inner sleeve couples to base pipe at both ends. The flow path is an annulus defined between the outer diameter of the inner sleeve and the inner diameter of the outer sleeve. Hydraulic seals are formed at the interfaces between the inner sleeve and base pipe and the outer sleeve and hydraulic screens. In practice, the assembled apparatus and hydraulic screens are ran downhole to a production zone using production tubing and a running tool. Fluid from the surface is pumped into the production tubing, diverted therefrom, and into chambers of the hydraulic screens using the flow path to conduct fluid between the hydraulic screens.

  • Publication number: 20220372836
    Abstract: Provided, in one aspect, is an anchor for use with a downhole tool in a wellbore. The anchor, according to this aspect, may include a base pipe; and one or more expandable chambers positioned radially about the base pipe. The one or more expandable chambers may, in some aspects, be configured to move from a first collapsed state to a second activated state; and the one or more expandable chambers may be operable to handle at least 20.7 Bar of internal pressure in the second activated state to engage a wall of a wellbore.

  • Patent number: 11448047
    Abstract: An adjustable flow control device. In one aspect, the flow control device comprises a base pipe having one or more openings extending from an exterior to an interior of the base pipe; and a movable sleeve positioned along the interior of the base pipe, the movable sleeve having one or more associated openings extending from an exterior to an interior of the movable sleeve, and configured to rotate to a first position that aligns a first of the base pipe openings with a first of the movable sleeve openings.

  • Patent number: 11365610
    Abstract: Disclosed herein are embodiments of a flow control device (FCD) module for use with hydraulic screens. In one embodiment, the FCD module comprises a base pipe having a port coupling an exterior of the base pipe and an interior of the base pipe; an FCD unit coupled to the base pipe about the port and configured to control production fluid from an oil and gas formation to the interior of the base pipe; one or more separate isolated activation channels extending along at least a portion of the base pipe, the one or more separate isolated activation channels configured to fluidly couple with one or more hydraulic activation chambers of a screen subassembly; and one or more covers surrounding the base pipe about the FCD unit, the one or more covers forming a production fluid channel between the screen subassembly and the FCD unit.
