    摘要: The application discloses a safety valve including a flapper valve and a packer assembly to be installed in a bore to isolate a first zone from a second zone. Preferably, the safety valve includes a hydraulic conduit bypassing the flapper valve to allow communication therethrough when the valve is closed. Furthermore, the safety valve preferably allows unobstructed passage of tools and fluids therethrough when the flapper valve is open. The application discloses a method to install a safety valve in an existing string of tubing by deploying a packer assembly having an integral safety valve.

    摘要: Apparatuses and methods to communicate with a zone below a subsurface safety valve (104, 204) independent of the position of a closure member (106) of the safety valve are disclosed. The apparatuses and methods include deploying a subsurface safety valve (104, 204) to a profile located within a string of production tubing. The subsurface safety valve (104, 204) is in communication with a surface station through an injection conduit (150,152; 250,252) and includes a bypass pathway (144, 244) to inject various fluids to a zone below.

    摘要: Apparatuses and methods to inject chemical stimulants (284) to a production zone (102, 202) through a string of production tubing (110, 210) around a downhole obstruction are disclosed. The apparatuses and methods include deploying an anchor seal assembly (200) to a landing profile (120, 220) located within a string of production tubing (110, 210). The anchor seal assembly (200) is in communication with a surface station through an injection conduit (260, 264) and includes a bypass pathway (262) to inject various fluids to a zone below.

    摘要: The application discloses a valve, which may include either a safety valve or a storm surge choke valve or the like, to isolate a zone below a valve from a string of production tubing. Preferably, the valve includes a flow interruption surface assembly, such as a flapper valve or a ball valve, displaced by an operating conduit extending from a surface location to the valve through the inside of the production tubing. The application also discloses a bypass-conduit inside the production tubing to allow communication from a surface location to the production zone when the valve is in either an open or a closed location.

    摘要: A safety valve (100) replaces an existing safety valve (102) in order to isolate a production zone from a tubing string when closed. Preferably the safety valve (100) includes a flow interruption device (106) displaced by an operating conduit extending from a surface location to the safety valve (100) through the inside of the production tubing. A by-pass conduit (150) allows communication from a surface location to the production zone through the safety valve (100) without affecting the operation of the safety valve (100).
