Abstract: The Invention is to be applied for selective injection of fluids in different formations, keeping the casing isolated from fluid pressure. “Fluid” is used in its widest sense: gases or liquids. It is hydraulically driven by the injection fluid. A single operator must only handle surface standard valves. It consists of five assemblies: Surface, Transport, Free Mandrel, Fixed Bottom Hole and Complementary. The Free Mandrel is the dynamic main device that carries all the Injection valves together, one for each formation, from the Bottom Hole to the Surface in 30? and viceversa. As this operation is performed many times in the well lifetime, it allows a cumulative time and money saving. Workover equipment is only used for installing the system and for fixing packers. Formation Pressure is kept when the system is installed or when it is pulled up. Changes can be made at any time when they are needed.

Abstract: A guide tube for continuous rod has a sections pivotably connected together by at least one translatable pivot. The tube connects to a rig at a fixed pivot and is initially folded on the rig for transport. To unfold and raise the tube for operation, a rig operator pivots a support rod pivotably connected to the tube away from the rig using a rope.

In this way, the winchline can be tensioned without the need for rig operators to perform a substantial amount of manual labor as conventionally done. Once the outer sections of the guide tube are lowered to the ground, the entire guide tube can be unfolded and raised with the tensioned winchline.
