The Tejas FlowGARD-DS™ Nipples are designed to be installed above OEM deep-set tubing retrievable safety valves to provide a location to land and lock secondary deep-set wireline retrievable insert safety valves (i.e. FlowGARD-DS Safety Valves).  Typically, deep-set tubing retrievable safety valves are not designed with communication features that allow failure mitigation with wireline insert safety valves.  The FlowGARD-DS™ Nipples provided a means for hydraulic communication from a surface hydraulic control line to either the tubing retrievable safety valve below, or to the secondary wireline retrievable insert safety valve.  FlowGARD-DS™ Nipples are rated to 15,000 psi and designed for use with either API standard weight or non-API heavy-weight production tubing and can be installed in sweet or severely corrosive well conditions.


All FlowGARD-DS™ Nipples feature proven metal-to-metal, Patented testable body joints, and hydraulic communication/isolation sealing technology.  They also feature field-proven testable hydraulic control line connections.  FlowGARD-DS™ Nipples can be supplied with a wide variety of locking profiles and polished bores.  They also allow for 'short' secondary wireline insert safety valves and provide significant outside diameter bypass for lower completion control line(s)/flatpack(s) clearance.


During normal operation, one of the OEM safety valve surface control lines (i.e. Line 1) is routed through the FlowGARD-DS™ Nipple and down to the safety valve via a short Jumper Control Line (shown above).  Until communicated, the hydraulic pathway through the FlowGARD-DS™ Nipple is 'transparent' to normal surface operations.  The other safety valve control line (i.e. Line 2) passes over the outside of the FlowGARD-DS™ Nipple down to the safety valve as usual during typical installations.  Once the FlowGARD-DS™ Nipple is shifted, all hydraulic communication to the tubing retrievable safety valve through the Jumper Control Line is completely and permanently isolated while the inside of the FlowGARD-DS™ Nipple is hydraulically communicated with the surface control line (i.e. Line 1) for the Tejas FlowGARD-DS™ secondary wireline retrievable insert safety valve control.
