Method of isolating and completing multiple zones within a wellbore
A gel barrier may be created within an annulus in a one-step operation by combining two or more solutions within the annulus. The two solutions may include a first solution, such as a silicate solution, and a second solution that may be an aqueous hardener solution. Once the two solutions are combined and subsequently reacted together, the forming of a gel barrier may occur between a plurality of zones along the annulus. The gel barrier may then prevent a fluid from traveling between adjacent zones of the wellbore annulus.
