| description | ZONE SELECT STAGE TOOL SYSTEM There is disclosed a stage tool (100) for cementing casing in a wellbore annulus, the tool comprising: a housing (101) disposed on the casing and having a first internal bore (102) and an exit port (114), the exit port (114) communicating the first internal bore (102) with the wellbore annulus; a breachable obstruction (115) disposed on the tool and preventing fluid communication through the exit port (114), the breachable obstruction (115) being exposed to the first internal bore (102) during deployment and initial operation of the stage tool (100), the breachable obstruction (115) breached in response to a first fluid pressure component in the first internal bore (102) acting against the breachable obstruction (115) and permitting fluid communication through the exit port (114) when breached; and a sleeve (130) movably disposed on the tool (100) at least from an initial position to a closed position relative to the exit port (114), wherein the sleeve (130) is an external sleeve movably disposed outside the housing (101), the sleeve (130) being in the initial position leaving the breachable obstruction (115) exposed during the deployment and initial operation of the stage tool (100), the sleeve (130) moving from the initial position to the closed position at least in part in response to a second fluid pressure component, the sleeve (130) in the closed position sealably covering the breached obstruction (115) from the first internal bore (102) and preventing fluid communication through the exit port (114). |
