Oil recovery by gravity drainage

Recent observations have indicated surprisingly high oil recoveries for gravity drainage. This has prompted the reexamination of gravity drainage as an oil recovery process. It is shown that oil relative permeability is a key factor. To measure this oil relative permeability accurately, a new method based on centrifugal gas-oil displacement in small cores is described. Several oil relative permeabilities for various rock types are presented. These relative permeabilities confirm that gravity drainage in water-wet connate-water-bearing reservoirs can be a very effective oil recovery process.
