ABSTRACT:
A method for recovering oil from an oil-bearing formation which comprises introducing into said formation to induce displacement of the oil contained therein, a fluid carrier containing from about 0.25 to about 100 parts by weight of a N,N-dimethylamide of a straight chain carboxylic acid per million parts of said fluid carrier, characterized in that said carboxylic acid contains from 12 to 18 carbon atoms. In addition, this invention encompasses the extraction of oil from mining oil sand operations which comprises the addition and then mixing into said sand to induce displacement of the oil contained thereon, a fluid carrier containing the N,N-dimethylamide.
