Abstract
The present invention is a method and apparatus for selectively activating and deactivating multiple, hydraulically-driven downhole tools (12, 14) with a system containing a single electrical line (30) and a single hydraulic line (28) which are connected in parallel to individual controllers (20, 22) associated with each down hole tool.
