@fathyesam Subsurface #Safety #Valve (SSSV) A subsurface safety valve (SSSV) is a safety device used in oil and gas wells to prevent the uncontrolled flow of fluids (#oil, #gas, or water) to the surface. It is installed downhole, typically near the bottom of the well, and is designed to close automatically in response to certain conditions to isolate the wellbore and prevent the escape of fluids. SSSVs are critical components in well control and safety systems, especially in #offshore #drilling
