1. A method for an underground gas storage reservoir management comprising:
obtaining feed from a domestic master gas system;
simultaneously injecting and reproducing in an underground gas storage via a plurality of dual producer and injector wells, wherein each of the dual producer and injector wells comprises and injection line and a reproduction line that connect to the master gas system and can operate both in an injector mode or in a reproducer mode, wherein the injection line and reproduction line are segregated; and
determining a pattern injection strategy, wherein the pattern injection strategy indicates which of the plurality of dual producer and injector wells is in injector mode and which of the plurality of dual producer and injector wells is in reproducer mode;
wherein the simultaneous injecting and reproducing in underground gas storage enhances the underground gas storage reservoir management by maximizing gas and condensate recovery;
wherein a switching cycle between dual operation modes in the plurality of dual producer and injector wells is improved for faster reaction times due to the segregated injection and reproduction lines comprised by each of the plurality of dual producer and injector wells.
