Original Abstract Submitted
A wellhead includes a tubing head adapter, a tubing hanger arranged within the tubing adapter, and a dual flapper back pressure valve arranged within the tubing hanger and including an elongate body having opposing upper and lower ends, an inner flowpath defined within the body and extending between the opposing upper and lower ends, and a flapper assembly arranged within the inner flow path and including a flapper pivotably mounted to an inner wall of the inner flow path at a pivoting mechanism. When the flapper is in a closed position, the flapper forms a sealed interface with the inner wall of the inner flow path that prevents fluids from circulating through the tubing hanger and through the inner flowpath from the lower end to the upper end.
