Abstract
Embodiments of a high flow, tubing insensitive, deep set wireline retrievable safety valve are disclosed herein. In one embodiment, a valve system for use downhole in a wellbore comprises a tubing retrievable safety valve (TRSV) and a secondary safety valve to be positioned within the TRSV. The secondary safety valve comprises at least a valve body having a valve seat at a downhole end; a piston; a rod coupled with the piston; a control line; a first pressure communication port, communicatively coupling the control line of safety valve with the TRSV control line; a balance line; and a second pressure communication port, communicatively coupling the balance line of the safety valve with the TRSV balance line; wherein the control line is configured to actuate the safety valve between an open position and a closed position in response to an intentional pressure change in the control line.
