Improved Recovery from Gulf of Mexico Reservoirs, Volume 4, Comparison of Methane, Nitrogen and Flue Gas for Attic Oil. February 14, 1995 - October 13, 1996. Final Report

Description

Gas injection for attic oil recovery was modeled in vertical sandpacks to compare the process performance characteristics of three gases, namely methane, nitrogen and flue gas. All of the gases tested recovered the same amount of oil over two cycles of gas injection. Nitrogen and flue gas recovered oil more rapidly than methane because a large portion of the methane slug dissolved in the oil phase and less free gas was available for oil displacement. The total gas utilization for two cycles of gas injection was somewhat better for nitrogen as compared to methane and flue gas. The lower nitrogen ... continued below

All of the gases tested recovered the same amount of oil over two cycles of gas injection. Nitrogen and flue gas recovered oil more rapidly than methane because a large portion of the methane slug dissolved in the oil phase and less free gas was available for oil displacement. The total gas utilization for two cycles of gas injection was somewhat better for nitrogen as compared to methane and flue gas. The lower nitrogen utilization was ascribed to the lower compressibility of nitrogen.
