Abstract
A downhole tool deployable within a wellbore for controlling the supply of treatment to fluid to a reservoir is disclosed. The downhole tool includes a housing defining a passage and a port extending through the housing. The housing includes a seat that is configured for deployment to a plug-receiving position for receiving a plug that is deployed through the passage. A key profile for effecting actuation of the seat to the plug-receiving position in response to registration of the key profile with a matching key on the plug being deployed through the passage is provided. The downhole tool further includes a flow control member configured for displacement relative to the port in response to application of a sufficient net force effected by a fluid pressure differential that is created by supplying pressurized fluid to the passage while the plug is deployed on the seat.
