... for this technology are on offshore production assets it was imperative that the function of the sub-surface safety valve was not compromised however given the cable was to be run inside the tubing string the existing safety valve would not be able to function. In a quick search for technology so address...

... improved and the benefits of additional data have been realized. Within the last few years, the first completions with all-electric Christmas trees (XT) were run. Because all-electric tubing retrievable downhole safety valves were not yet available, these were not true all-electric completions. These first...

... and maintain it right is the company philosphy on equipment maintenance. In an ideal condition, there should be no pressure on any annulus of the well unless with special purposes eg; gas lifted well. All the wellhead valves and the downhole safety valves must be function properly and no fluid passage when...

...Introduction Basically, a downhole safety valve is a well completion component which acts as a failsafe mechanism in case of emergency to prevent any wellbore fluids and pressure from being released to the surface. A few examples of catastrophic or emergency events which could lead...

... Once the JT has been deployed, a safety valve and quick-connect are installed on top to provide a safe barrier between the competing strings for pressure-control and disconnect at surface following the completion of downhole operations. The continuous movement advantage offered by the CT allows...
