FORMULATIONS OF COLLOIDAL DISPERSION GELS AND SURFACTANTS FOR THE IMPROVED RECOVERY OF PETROLEUM AND METHOD OF OBTAINING THESE FORMULATIONS

摘要

The invention relates to formulations of colloidal dispersions and surfactants and to the method of obtaining them, for the recovery of hydrocarbons. The formulation comprises a surfactant system composed of various surfactant families and a colloidal dispersion gel which are obtained from the mixture of polymer and a crosslinker. The formulation can be used in processes in which chemical substances are injected in order to improve the recovery factor in water-injection processes.
