Claim Text:
1. A method for hydrocarbon resource recovery in a subterranean formation comprising: forming a laterally extending injector well in the subterranean formation; forming a laterally extending producer well spaced below the injector well; radio frequency (RF) heating the subterranean formation to establish hydraulic communication between the injector well and the producer well; injecting at least one of an inert gas, propane, and methane into the injector well to assist with the hydraulic communication between the injector well and the producer well by at least displacing hydrocarbon resources from the injector well to the producer well; determining whether hydraulic communication has been established between the injector well and the producer well; and when hydraulic communication has been established between the injector well and the producer well, injecting heated liquid water into the injector well to recover the hydrocarbon resources from the producer well based upon the hydraulic communication therebetween.
