Anti Blow-up Tool
The ACT Anti Blow Up Tool is a wireline service tool designed to be used as part of
the toolstring when downhole instruments are to be deployed in to a multi zone completion
well.
The ACT Anti Blow Up Tool will help to prevent a toolstring being blown up the
production string if the flow rates between zones should try to push the toolstring upwards.
The ACT Anti Blow Up Tool has been designed so that if the lower part of the
toolstring starts to lift, two arms are thrown outward to lock into the tubing wall, stopping
any further upward movement. To release the arms, once engaged, you simply pick up on
the wireline which lifts the upper body of the tool and closes the arms, releasing the
toolstring.
The ACT Anti Blow Up Tool is available to suit all tubing sizes from 2-3/8" through to
5-1/2".
