1. A method comprising:
providing a treatment fluid that comprises an aqueous base fluid, a viscoelastic surfactant, and a soap component;
wherein the viscoelastic surfactant and the soap component are selected such that the viscoelastic surfactant dissolves substantially all of the soap component and a maximum amount of the soap component is dissolved in the viscoelastic surfactant without adversely affecting a target viscosity of the treatment fluid and any portion of the soap component that is not dissolved in the viscoelastic surfactant is present in the treatment fluid in a solid phase;wherein the soap component is present in the treatment fluid in an amount in the range of about 1% to about 5% by volume of the treatment fluid;wherein the soap component is selected from the group consisting of 4,7,10,13,16,19-docosahexaenoic acid; 4,7,10,13,16-docosapentaenoic acid; 5,8,11,14,17-eicosapentaenoic acid; 7,10,13,16,19-docosapentaenoic acid; and any combinations thereof; andwherein the treatment fluid is substantially free of a non-aqueous solvent capable of dissolving the soap component; and placing an amount of the treatment fluid in a subterranean formation penetrated by a well bore to create a fluid diverting barrier sufficient to provide conformance control;
wherein the soap component of the treatment fluid interacts with a metal ion present in the subterranean formation to form a precipitate wherein the precipitate reduces the permeability of at least a portion of the subterranean formation to an aqueous fluid, a gas, or a combination thereof. |
