ABSTRACT:
A method and associated apparatus provide enhanced safety in subterranean well completions while permitting other production issues to be addressed efficiently and cost effectively. In a preferred embodiment, a method of producing a subterranean well utilizes an isolation packer having an inner mandrel through which fluid transmission lines and electrical transmission lines may be conveniently installed. A unique configuration of the packer permits a surface controlled subsurface safety valve, fluid property sensors, injection subs, etc., to be installed below the packer with the various lines used therewith extended axially through the mandrel.
