Patent ID: 8043999

Claim:
A method of treating a surface in contact with a wellbore and/or a subterranean formation penetrated by a well bore, comprising: providing a treatment composition comprising a rheological polymer, a partitioning agent, a charged polyelectrolyte, and a first liquid medium; forming a stabilized heterogeneous mixture comprising a dispersed rheological polymer-rich phase and a partitioning agent-rich phase, wherein the mixing step comprises at least partially hydrating the rheological polymer; diluting the heterogeneous mixture with a second liquid medium miscible with the first liquid medium to mutually dissolve the polymer-rich phase and the partitioning-agent rich phase to form a well treatment fluid comprising a continuous mixed polymer-agent phase, wherein the continuous mixed polymer-agent phase has an apparent viscosity at 1 1/s and 25° C. that is greater than the bulk apparent viscosity of the heterogeneous mixture; and injecting the treatment fluid into the well bore.
