Abstract
A method for placing a plug at a predetermined location in a wellbore, the method being based on utilising a supporting fluid solidifying after being subjected to shear forces. After placing the supporting fluid and allowing it to develop sufficient strength, the plug material is injected. A preferred example of the fluid is an emulsion comprising polymer material and crosslinking agent separated by phase boundaries prior to the shearing process.
