Miscible oil-recovery methods include many techniques which may recover 90% or more of oil in place. Special injected fluids wash crude from pores of contacted rock to form an oil bank. The gravity range normally applicable to miscible processes is 30/sup 0/ to 40/sup 0/ API. A major economic consideration is the cost of additives to achieve miscibility with cheaper, higher-volume drive fluids. Operating cost curves based on field data show typical application ranges for several processes. Other data illustrate how slug size and composition affect recovery. Five attractive processes are high pressure miscible, enriched gas drive, LPG slugs, alcohol flood, and micellar solutions. The first 3 processes are designed to be effective with pressures of 1,000 to 5,000 psi, or higher. The last 2 can achieve miscibility at atmospheric pressure, giving a wide range of applicable processes for consideration--from shallowest reservoirs to deeper high potential developments.
