Methods for servicing subterranean wells
Pumpable process-fluid compositions and methods for establishing hydraulic isolation in cemented subterranean wells comprise more than 1 wt % polyacrylamide and a non-metallic crosslinker. Upon entering voids and cracks in or adjacent to a cement sheath, and contacting the set-cement surfaces, the compositions react and form a seal that prevents further leakage.
