ABSTRACT:
A non-rigid carrier conveys a pump and/or the steam generator through a bore of the production tubing string to support enhanced oil recovery operations. An annular space separates the production tubing string and a wall of a wellbore intersecting a hydrocarbon-bearing subterranean formation. Using the non-rigid carrier, the steam generator is conveyed into the wellbore and operated to inject hot gases into the formation through the perforations in the casing. Afterwards, the steam generator is conveyed out of the cased wellbore and the pump is conveyed into the cased wellbore and operated to pump hydrocarbons to the surface. For cyclic injection operations, the pump may be retrieved to the surface and the steam generator may be returned into the well. The production tubing string, such as a production tubing, remains in the well while the pump and/or the steam generator are conveyed up and down the cased well. A base installed in the cased well receives either the pump or the steam generator.
