Abstract
A shut-in valve tool for use in a well has 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. The tool has an inlet port defined in the tool body through which well fluid must flow to enter the flow path. The tool has 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. The tool has 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.
