Abstract
Safety valves and methods of using safety valves. The safety valve is provided to a wellbore having a hydrostatic pressure. The safety valve is configured to operate at tubing well pressure. Pressure is applied to the safety valve with a single control line. The safety valve uses an accumulator in fluidic communication with the control line such that pressure acting on the accumulator is fluidically connected to pressure in the control line. The safety valve is insensitive to the hydrostatic pressure.
