A process for recovering oil from oil containing masses and formations by contacting such oil bearing masses with waste foul condensates, known as black liquor, from paper and pulping operations, thereby to free the oil present or bound up in such masses and simultaneously provide a use for the heretofore considered unusable black liquors, the disposal of which up to now have presented both an economical and ecological problem.
