Abstract
A safety system for a well having a cable deployed electronic submersible pump includes a barrier valve having a control line for opening and closing the valve, a first flapper safety valve assembly, and a second flapper safety valve assembly. The second flapper safety valve allows the cable for the pump to pass through the second flapper safety valve when the valve is in a closed position. An integral flapper safety valve assembly incorporates the first and second flapper safety valves.
