Methods of producing a sour hydrocarbon gas via production tubing intersecti ng a reservoir, are described, one method including contacting an underground reservoir with an aqueous composition optionally comprising an additive, the reservoir comprising hydrocarbons and sulfur compounds; displacing the composition into the reservoir by forcing a fluid (which may be a non-hydrocarbon gas, or inert gas, or nitrogen, or argon, or mixture thereof), into the reservoir, or into the production tubing; and producing at least some of the hydrocarbons and sulfur compounds from the reservoir throu gh the production tubing, the composition wetting the production tubing and preventing substantial deposition of elemental sulfur thereon.
