Abstract:
1. A method of producing a sour hydrocarbon gas from a reservoir, the method comprising: a) injecting an aqueous composition consisting essentially of water into a well within the reservoir so as to contact at least a portion of the reservoir with the aqueous composition, the well having production tubing, and the reservoir comprising hydrocarbons and sulfur compounds; b) injecting an inert gas into the well to force the aqueous composition further into the reservoir; c) producing at least some of the hydrocarbons and sulfur compounds mixed with the aqueous composition from the reservoir; and d) repeating (a) through (c) wherein the aqueous composition consists of only water and no additives, the aqueous composition consisting of only water and no additives wetting the production tubing and preventing substantial deposition of elemental sulfur on the production tubing.
