Abstract: A wellbore completion apparatus includes an engager having an engageable surface configured for becoming engaged to a surface of the wellbore is disclosed. The apparatus is configurable in an engagement-ready state and an engagement state. Actuation of the apparatus such that it transitions from the engagement-ready state to the engagement state is with effect that the engageable surface becomes engaged to the wellbore surface. In the engagement-ready state, the engager can include a first free end and a second free end, and the transitioning to the engagement steady is effected in response to relative displacement between the first and second free ends. In the engagement state, the engager can be configured in a loop configuration.

Abstract: The present invention provides an actuation member for traveling down a borehole of a casing to engage with one or more geometrical profile locations provided inside the casing, and a system for controllably exposing selected locations along the wellbore to a pressurized fluid. The actuation member comprises a generally cylindrical hollow body extending between an uphole end and a downhole end, and a plug seat configured to receive a plug for blocking the borehole. The actuation member has two edge portions separate and movable relative to one another to facilitate resilient deformation of the hollow body, wherein the deformation causes a reduction of cross-sectional area of the hollow body. An outer surface of the hollow body comprises one or more protrusions and/or grooves configured to matingly engage with the one or more geometric profile locations in the casing.

Abstract: There is provided a fluid flow conducting apparatus comprising: a housing, a housing passage configured for conducting fluid through the housing, and a flow controller for controlling flow communication between the housing passage and an environment external to the housing. The flow controller includes a sealed interface-effector. The flow controller is disposed in a first configuration, and adapted for disposition in a second configuration in response to disposition of the sealed interface-effector in communication with a degradation-promoting agent such that degradation of the sealed interface effector is effected. In the first configuration, the sealed interface effector is threadably coupled to the housing and defines a sealed interface between the housing passage and the environment external to the housing. In the second configuration, the sealed interface is defeated.
