Abstract
Gellable treatment fluids containing an amps-acrylamide bipolymer and a suitable surfactant can be used in various subterranean operations where it is necessary for the treatment fluid to remain in a gelled state for extended periods of time at high formation temperatures. The gellable treatment fluids are thermally-stable, solids-free self-degrading treatment fluid compositions useful in fluid loss pill, kill pill, perforation pill and other gel treatment applications.
