Abstract:
1. A method to inject fluid into a well below a subsurface safety valve comprising: deploying a subsurface safety valve to a string of production tubing, the string of production tubing including a landing profile, the subsurface safety valve including a flapper disc, an upper injection conduit and a lower injection conduit extending from the subsurface safety valve to a lower zone, said lower injection conduit in communication with the upper injection conduit through a bypass pathway of the subsurface safety valve; engaging the subsurface safety valve into the landing profile; extending an actuation conduit to the subsurface safety valve through a bore of the string of production tubing; actuating the flapper disc between an open position and a closed position through the actuation conduit; and injecting a fluid from a surface location to the lower zone through the upper injection conduit, the bypass pathway, and the lower injection conduit.
