ABSTRACT:
A landing nipple and safety system for installation in wells having a submersible pump for pumping well fluids to the surface plus a subsurface safety valve for maintaining the well under control during installation and removal of the pump from the well. The subsurface safety valve is hydraulically actuated by the discharge pressure of the pump. The landing nipple on which the pump is mounted and in which the safety valve is installed can be retrieved from the flow conductor by conventional wireline techniques.
