Granted: 2014-11-18
Abstract: An apparatus for opening and closing downhole tools, such as sliding sleeves, includes a first (opening) shifting tool connected to an end of a continuous rod, an intermediate rod connected below the first shifting tool, and a second (closing) shifting tool connected to the end of the intermediate rod. The first tool has a profile for selectively opening sleeves when moved downhole, and the second tool has a profile for selectively closing sleeves when moved uphole. Alternatively, a single tool can couple to the end of the continuous rod and can have the profiles for opening and closing sleeves. When used, the continuous rod and shifting tools are deployed downhole to a series of sliding sleeves on a tool string. Manipulated by the continuous rod and a rig at the surface, the shifting tools are used to successively open and close the sliding sleeves so that successive isolated zones of a formation can be treated with frac fluid.

Abstract: A well installation comprising metallic structure including downhole metallic tubing (11, 12) for conveying product towards the surface, a sub surface safety valve (2) disposed in the downhole metallic tubing for interrupting flow of product towards the surface when closed and allowing flow of product towards the surface when open. Also provided are valve control means (3) disposed downhole and arranged for detecting electrical signals in the downhole metallic tubing and for holding the valve open whilst receiving an electrical signal, and surface signalling means (4) for applying an electrical signal to metallic structure of the well for transmission via the downhole metallic tubing towards the valve control means so as to hold the valve open.  The system can be made more robust by ensuring that the control means (3) will only hold the valve open whilst receiving a signal of given characteristics to help prevent stray currents erroneously holding the valve open. This signal selective aspect of the system may be implemented using a tuned impedance generation means (32).
