Abstract

A shut-in valve tool for use in a well, comprising; a tool body defining a flow path for the flow of well fluid from outside the tool through the tool body to another part of the well; an inlet port defined in the tool body though which well fluid must flow to enter the flow path; a sliding valve member located within the tool body and moveable between a first position in which the inlet port is open, and a second position in which the inlet port is blocked; a supply of compressed fluid; and an actuating mechanism which uses the compressed fluid for driving the sliding valve member from the first position to the second position.
