摘要： Systems and methods for stimulating a plurality of zones of a subterranean formation to increase production of reservoir fluids therefrom. The subterranean formation contains a well that includes a liner that defines a liner conduit, and the systems and methods include stimulating the plurality of zones with a stimulation assembly that is present within the liner conduit without requiring removal of the stimulation assembly from the liner conduit. The stimulation assembly includes a perforation device, which is configured to selectively form one or more perforations in a plurality of portions of the liner, and a resettable sealing device, which is configured to fluidly isolate the plurality of portions of the liner from a plurality of respective downhole portions of the liner. The fluid isolation provides for selective introduction of a stimulant fluid to a selected zone of the subterranean formation that is associated with a corresponding portion of the liner.

摘要： A method comprising moving a shifting tool in a first direction through a moveable member positioned in a casing of a wellbore, including moving the shifting tool through a shifting tool interface member (STIM) adjacent the moveable member, until the shifting tool is positioned past the moveable member and the STIM. The shifting tool is then moved in a second direction substantially opposite the first direction until the shifting tool and the STIM engage. The shifting tool is then further moved in the second direction, thereby moving the STIM and the moveable member in the second direction, until the STIM substantially simultaneously (1) engages the casing and (2) disengages the shifting tool.

摘要： Systems and methods for secondary sealing of a perforation present within a wellbore casing associated with a primary sealing agent. The wellbore casing defines a casing conduit present within a wellbore that extends between a surface region and a subterranean formation. The systems and methods include a sealing apparatus that retains a charge of sealing material with a secondary sealing agent and is conveyed within the casing conduit to within a threshold distance of the perforation. The systems and methods further include selectively releasing the charge of sealing material from the sealing apparatus, such as by a release mechanism, to deliver the charge of sealing material to the perforation, to supplement the primary sealing agent (and/or a seal formed thereby), and/or to decrease a flow rate of a fluid from the casing conduit through the perforation.

摘要： Embodiments of a bottomhole assembly BHA for completion of a wellbore are deployed on electrically-enabled coiled tubing (CT) and permit components of the BHA to be independently electrically actuated from surface for completion of multiple zones in a single trip using a single BHA having at least two electrically-actuated variable diameter packers. One or both of the packers may be actuated to expand or retract for opening and closing off a variety of flowpaths between the BHA and the wellbore, in new wellbores, old wellbores, cased wellbores, wellbores with sleeves and in openhole wellbores. Additional components in the BHA, which may also be electrically–actuated or powered, permit perforating, locating of the BHA in the wellbore such as using casing collar locators and microseismic monitoring in real time or in memory mode.
