FIELD: chemistry.
SUBSTANCE: in the method for control of filtration losses in a formation comprising pumping an aqueous liquid containing an emulsion stabilized with a surfactant and having an internal bitumen phase, the bitumen emulsion is converted in the formation by addition of an emulsifying agent initiator. The invention is developed in dependent points of the formula.
EFFECT: increased efficiency of treatment.
