Method to increase the stability of a water in oil emulsion stabilized with solids, and water - in - oil emulsion stabilized with solids ".Method to increase the stability of a water in oil emulsion stabilized with solids by means of pre - treatment of the oil before emulsification.The step of pre - treatment can be carried out by adding dilute acid to be oil, add a lignosulfonate additive to oil, sulfonar oil, heat the oil to oxidize.Heat the oil in a deal with inert environment, and combinations thereof.The emulsion can be used in increased oil recovery methods, including using the emulsion as a fluid drag to displace hydrocarbons in a subterranean formation.And using the emulsion as a barrier fluid to divert the flow of fluids in the formation.
