Abstract
An aqueous fluid is gelled in a productive zone of a subterranean formation to create a temporary fluid-impermeable barrier. The fluid contains nanoparticles, a polyacrylamide having a weight average molecular weight from about 1.5 million to 22 million Dalton and an encapsulated liquid crosslinking agent. Upon release of the liquid crosslinking agent, the barrier is formed by crosslinking the polyacrylamide. The nanoparticles remain dispersed in the crosslinked gel. The fluid-impermeable barrier is effective over a period of at least 1 hour up to 2 weeks while the downhole temperature in the well is at least 300° C.
