Abstract
Apparatuses and methods to communicate with a zone below a subsurface safety valve () independent of the position of a closure member () of the safety valve. The apparatuses and methods include deploying a subsurface safety valve () to a profile located within a string of production tubing. The subsurface safety valve () is in communication with a surface station through an injection conduit () and includes a bypass pathway () to inject various fluids to a zone below. A redundant control to actuate subsurface safety valve () can include a three-way valve () or three-way manifoldconnecting the injection conduit () or the hydraulic ports () to the subsurface safety valve ().
