System (100) comprising a valve (1) and a packer (26) for controlling a location of a displacement fluid (94) or a treatment fluid (96) in a low pressure well where a well bore (2) extends into and communicates with a reservoir formation (10), said valve (1) comprises: - a valve housing (12); - a pressure activated valve body (14) that is axially movable in the valve housing (12) between a closed position and at least a partly open position, the valve body (14) has a surface (30) facing a pressurized liquid, and where the movement of the valve body (14) is opposed by a resilient element (16), and the valve (1) is designed to open at a specific pressure; - the valve housing (12) has at least one valve opening (24) that is exposed for pressurized fluid when the valve body (14) is moved to its at least partly open position, and such that the packer (26) is peripherally positioned at the outside of the valve housing (12), and the system (100) is adapted to be releasable connected to a string (5), said string (5) consisting of a coiled tubing or a wireline. It is also described a method for controlling the location of a treatment fluid (96) in a low pressure well by using the system. |
