Oil recovery with micellar dispersions contg. sulphonates - prepd. from gas oil contg. oxygenated hydrocarbons

In the recovery of oil from subterranean oil-bearing formations by injection of a micellar dispersion consisting of hydrocarbons, a petroleum sulphonate and an aq. medium, the petroleum sulphonate is prepd. by sulphonating a gas oil contg. 1-50 (pref. 3-35) wt% of oxygenated hydrocarbons. It is not...

Summary:In the recovery of oil from subterranean oil-bearing formations by injection of a micellar dispersion consisting of hydrocarbons, a petroleum sulphonate and an aq. medium, the petroleum sulphonate is prepd. by sulphonating a gas oil contg. 1-50 (pref. 3-35) wt% of oxygenated hydrocarbons. It is not necessary to extract the petroleum sulphonate from the sulphonation mixt., thus avoiding laborious and costly solvent extraction. The sulphonates obtd. give better oil recovery yields than those obtd. without the use of oxygenated hydrocarbons.
