Abstract:
The invention provides a method and system for treating a subterranean formation by detecting the displacement and position of a downhole fluid having a pH through the fluids reaction with a pH-sensitive material, mobilizing a plug assembly comprising the material to contact one or more constrictions in a wellbore casing.

Claim (Index 1):
A method for treating a subterranean formation, comprising:\n a. displacing a fluid having a pH through a wellbore in the subterranean formation, the wellbore having a casing, wherein:\n i. the casing comprises at least one plug assembly comprising a plug, wherein the plug assembly is in slidable connection to the inside wall of the casing,\n wherein the plug assembly is stationary in the absence of the fluid having the pH; \n and \n wherein the plug assembly comprises a pH-sensitive material that is selectively reactive to the fluid having the pH, such that contact of the material with the fluid mobilizes the plug assembly through the casing; and \n \n ii. at least one stationary constriction attached to the inside casing wall on the side of the plug assembly opposite to the direction of flow of the fluid having the pH; \n b. displacing the plug assembly through the casing in the direction of flow of the fluid having the pH, whereby the plug assembly remains in substantial proximity to the leading edge of the fluid having the pH; and c. detecting contact of the plug assembly with at least one constriction, thereby indicating displacement of the fluid having the pH through the casing.
