摘要: Improved gas foam flooding surfactants and gas foam-forming mixtures wherein the surfactants are enriched in olefin disulfonate. The surfactants may be used in either a gas drive or a gas soak process. Use of the disulfonate-enriched gas foam surfactants and mixtures in a gas flooding operation is also described.

摘要: An improved process for recovering oil by injecting a mixture of noncondensible gas and gas foam surfactant into an oil-containing subterranean reservoir, the improvement provided by using a surfactant enriched in olefin disulfonate. The sulfactant may be used in either a gas drive or a gas soak process. Disulfonate-enriched gas foam surfactants and mixtures are also described.

摘要: Polymers used to prevent fluid loss from boreholes may be eliminated after a predetermined time by including with the polymer composition halogen-substituted organic acids or their salt derivatives. These components hydrolyze, releasing hydrogen-halogen acids which break down the polymers within the wellbore or formation.

摘要: Oil is produced from an ion-exchanging reservoir by a dual gradient-establishing injection of a relatively short and concentrated slug of hot aqueous fluid containing surfactant and monovalent salt, followed by a steam-foaming mixture in which stem is mixed with much less of each of the surfactant and salt.
