fluid viscosity in the reservoir further increases production even using the downhole fluid lift system can slow at this point system 100 can be reconfigured for injection by closing valves 125 126 and by activating the downhole fluid lift system 118 to circulate cooling water and the downhole fluid heater 120 to repeat the cycle described above such systems and methods can increase operational efficiencies because a single completion assembly can be installed in a well bore and remain in place during both injection and production phases of a cyclic production process this reduces the number of trips in and out of the whole that would otherwise be required for systems and methods based on the use of separate injection and production assemblies the concepts described above can be implemented in a variety of systems and or system configurations for example other approaches can be used to cool the downhole fluid lift system similarly other downhole fluid lift systems can be used fig2 depicts an alternate approach to cooling the downhole fluid lift system and other components in the uphole portion of the well bore 114 a system 200 can be arranged in substantially the same configuration as system 100 however system 200 can use the surface pump to circulate cooling water through the uphole annulus 128 of the well bore 114 during the heated fluid injection phase this can reduce the overall use of downhole fluid lift system 118 and thus can reduce the likelihood of wear related damage to the downhole fluid lift system the surface pump can be the pump 142 used to supply water to the downhole fluid heater 120 or a separate pump can be used fig3 depicts yet another alternate approach to cooling the downhole fluid lift.
