Presented are main physical-chemical properties of oil samples from, Irelya
hskoye field in Yakutiya, and, also, aggregated stability of oil emulsions
from this field. Studied are reological parameters of emulsions with 30% wa
ter-cut in the presence of different agents and under different temperature
s. Determined are most effective de-emulsifying agents, applied in oil trea
tment facilities at this field.
