ABSTRACT:
Method and apparatus for altering the downhole flow path of control fluids or the like in oil and gas wells. A downhole side pocket mandrel in a tubing string has interconnected thereto a supply conduit from the surface and a plurality of receiving conduits. Each receiving conduit is connected to a control device. A plurality of different plug assemblies is provided, each for completing within the mandrel pocket when disposed therein a different hydraulic flow path between the supply conduit and one or more receiving conduits. The plug assemblies are insertable into and retrievable from the mandrel pocket by conventional running tools. Any desired control device may thereby be controlled at the surface with a single supply conduit by selection of the proper plug assembly. In a preferred embodiment, the plug assemblies are comprised of a plurality of subplugs which may be interconnected in differing orders to form the desired plug assembly.
