Methods and apparatuses for producing natural gas are provided. One method includes a more efficient utilization of hydrocarbons. The method includes providing a gas cycling operation comprising a gaseous feed stream from a gas reservoir, treating the gaseous feed stream to form at least a gaseous cycle stream, and injecting the gaseous cycle stream into the gas reservoir; substituting at least a portion of the gaseous cycle stream with a treated tail gas; and utilizing the at least a portion of the gaseous cycle stream for a non-reservoir application such as sales or fuel. The tail gas can be from any location and any type of process, but is a result of a sulfur recovery process such as a Claus unit. The Claus unit may be associated with the gas cycling reservoir, another reservoir, a refinery, or other operation. |
