Method to control the physical interface between two or more fluids

A method of servicing a wellbore comprising:

• preparing a liquid plug;
• allowing the liquid plug to polymerize into a highly deformable elastic plug prior to placement in the wellbore wherein the polymerization occurs in from about 60 minutes to about 300 minutes, and wherein the highly deformable elastic plug comprises a highly deformable solid approximating Hookean behavior at compressive strains up to 50%;
• combining the highly deformable elastic plug with at least one conventional plug to form a plug combination;
• and
• placing the plug combination into a wellbore.
