摘要

P recovery of petroleum, by increasing the index of wall injectivity of micellar media containing the crude petroleum sulfonates. / p & & p & the method consists, in particular, to bring the micellar medium in contact with an extraction agent of paraffins, in a proportion of 0,5 to 10% by weight of the sulfonate of crude petroleum, to allow the mixture obtained is separated into two stages, to separate the phase containing the paraffin and the extraction agent and then to add the medium thus extracted in the underground formation, containing the oil in order to extract the oil that -. & / p & & p & drilling and extraction of oil and the like. / p
