Claim 19:
20. A well completion system for producing reservoir fluids from a reservoir via a wellbore provided in the reservoir, comprising:
a wellbore string extending along the wellbore and comprising an injection conduit defining an injection fluid passage adapted to convey injection fluid to the reservoir, and a production conduit defining a production fluid passage adapted to convey production fluid from the reservoir to surface; and
a frac valve system coupled to the injection and production conduits, the frac valve system comprising a plurality of frac valves having respective frac ports operable to enable the injection of fracturing fluid therethrough for fracturing the reservoir, the frac ports being defined through one of the injection and production conduits to enable conveyance of the fracturing fluid from the wellbore string to the reservoir via a single conduit; and
wherein the wellbore string and the frac valve system are configured to alternately (i) inject the injection fluid into the formation and (ii) produce reservoir fluid from the formation.
