Abstract
An apparatus is provided for injecting fluid within the bore of a subterranean well. The fluid is transmitted through the bore above the apparatus through parallel fluid flow conduits. A packer assembly communicates to the fluid flow conduits and is carriable on at least one of the conduits. Concentric flow means are defined through the packer assembly for transmission of fluid and communicate with the fluid flow conduits and a production zone within the well. Receptacle means are carried on the packer assembly and communicate between the fluid flow conduits and the concentric flow means. Casing gripping means which are fluid pressure responsive are defined around the packer assembly and are responsive to each of predeterminable pressure increase from fluid flow from the top of the well within one of the fluid flow conduits and within the well below the packer assembly, whereby the gripping means are urged to gripping engagement with the casing to prevent movement of the apparatus in one direction.
