Claim:
1. A method of using a water based solution having a controllable gel time, the method comprising: providing a predetermined ratio of a water soluble silicate solution having at least one alkali metal; providing a predetermined ratio of a non-crosslinked water dispersible polymer; providing a predetermined ratio of a water soluble initiator containing at least one organic reactive carbonyl compound other than aldehyde; and combining the water soluble silicate solution, the dispersible polymer, and the water soluble initiator to form a single stage alkaline fluid containing the non-crosslinked polymer; injecting the single stage alkaline fluid containing the non-crosslinked polymer into fluid flow channels; plugging and sealing of said fluid flow channels with said single stage alkaline fluid containing the non-crosslinked polymer; and blocking flow of fluids through said fluid flow channels with said single stage fluid containing the non-crosslinked polymer.
