Use of water-external micellar dispersion in oil recovery
Patent
·
OSTI ID:5143981
A water-external micellar dispersion comprised of water, hydrocarbon, and petroleum sulfonate is useful in secondary- type recovery processes (especially tertiary recovery) to recover crude oil from subterranean formations. The micellar dispersion contains semi-polar compounds and optionally electrolyte. The injection of about 1 to 20% formation pore volume of the micellar dispersion provides efficient recovery of crude oil. The micellar dispersion can be followed by a mobility buffer, one purpose of which is to protect the dispersion from invasion of a subsequent water drive. (23 claims)
