... Abstract The evolution of subsurface safety valve design for HPHT application has created the need for advanced design verification and validation testing to ensure "fit-for-service" application in a HPHT environment. With the release of API 14A 12 th edition and the new V-1H validation grade...

... was developed as an extension within the existing K5F field with two Christmas trees K5F1 and K5F2 already on stream and in production since 2008. These two Christmas trees were the first all-electric DC subsea production control system. Only for the surface-controlled subsurface safety valve (SCSSV), which...

... for both performance and reliability. These tools mustperform throughout the life of the well, which is extremely challenging whenoperating these tools in HP/HT environments. For such a development, everyfeature within the subsurface safety valve must be evaluated and scrutinizedand considered against...

... Abstract The typical subsurface safety valve for deepwater high-pressure/high-temperature (HP/HT) subsea applications employs many operational techniques including pressure-balanced pistons using gas energy for assisted closure, hydraulic balance lines, or a heavy spring to ensure failsafe...

... The subsurface safety valve is a critical component in the performance of subsea production systems. Until recently, wellbore temperatures and pressures have been low, and control fluids and subsurface safety valves to satisfactorily meet the reservoir conditions could be selected with few problems...
