Abstract
A sub-surface safety valve (SSSV) for use in a low temperature downhole environment. The low temperature environment can be created by injection of fluid such as carbon dioxide. The low temperature downhole environment may be detrimental to the SSSV by damaging elastomer seals. The disclosed SSSV utilizes non-elastomeric seals and metal-to-metal seals between components. The SSSV utilizes metal-to-metal threads between body joints eliminating the need for an elastomers in the threads between body joints. Creating a SSSV with an elastomer seal reduces fatigue and damage in a low temperature environment.
