Abstract (en)
[origin: WO2018098592A1] An apparatus for deployment in a wellbore to control flow of fluids between the wellbore and a subterranean reservoir is provided, comprising: a housing; a port extending through the housing; a passage disposed within the housing; and a flow control member, releasably retained relative to the housing and disposed relative to the port such that the port is disposed in a closed condition, and including a frangible portion. The flow control member, the housing, and the port are co- operatively configured such that, in response to application of a sufficient force for urging displacement of the flow control member in a first direction: the flow control member becomes released from the retention relative to the housing; after the release of the flow control member from the retention relative to the housing, the flow control member is displaced, relative to the port, in the first direction; and while the flow control member is being displaced, relative to the port, in the first direction, the displacement of the flow control member is impeded by an interaction between the flow control member and the housing.
