Abstract: Subsurface apparatus and method for using same in a hydrocarbon producing well to enable retrieval of a full opening subsurface safety valve mounted in the well tubing without disturbing the major portion of the well tubing located below the safety valve. The apparatus includes a subsurface tubing hanger below the safety valve from which the major portion of the well tubing is suspended and through which tubing the hydrocarbons flow to the surface. Disposed above the safety valve is a tubing holddown apparatus and a controllable safety joint. The holddown apparatus provides a lower anchor for the portion of the tubing disposed above the tubing hanger and the stinger which is received in and seals with the tubing hanger.
