ABSTRACT:
Well bores employed for production of hydrocarbons having open hole completion and zonal breakdown in the locus of the well bore are recompleted, advantageously for injection of a fluid such as CO.sub.2 in an enhanced oil recovery process. Recompletion is effected by packing off the open hole interval, emplacing a particulate material in the packed off interval and broken down zone, adhering the particulates together with an adhesive to form a permeable synthetic rock-like material, reaming out the open hole interval to a greater diameter than the original completion, setting a casing over the open hole interval, cementing between the casing and the reamed out hole, and perforating at the zones to be isolated and to be communicated with from the well bore, e.g., for CO.sub.2 injection.
