Abstract: A method of tracking a treatment fluid in a subterranean formation penetrated by a wellbore provides for injecting the treatment fluid with the plurality of tracer agents into the well and the formation. The tracer agents are high viscous liquid droplets having a diameter of not more than 1000 nm. Location and distribution of the treatment fluid is determined by detecting changes in physical properties of the formation caused by arrival of the treatment fluid comprising the plurality of the tracer agents.
