Method of oil recovery with a hot driving fluid

Patent ·
OSTI ID:5922198
Recovery of oil from an oil stratum is improved by injecting a slug of an oil or water solution of surfactant stable at temperatures up to at least 650$F into the stratum. This is followed with a driving fluid free of surfactant. The oil is produced through a well penetrating the stratum, injection and production being effected through a single well by so-called ''huff and puff'' or through spaced-apart injection and producing wells.
