Abstract:
Crosslinked polymers that may be useful, for example, as viscosifiers or fluid-loss control additives for well treatment and servicing fluids are provided. In one embodiment, the methods comprise: providing a treatment fluid comprising a base fluid and a crosslinked polymer composition comprising at least one polymer that comprise at least one N-vinyl lactam monomeric unit, and at least one crosslinker selected from the group consisting of: an acrylamide-based crosslinker, an acrylate-based crosslinker, an ester-based crosslinker, an amide-based crosslinker, any derivative thereof, and any combination thereof; and introducing the treatment fluid into at least a portion of a wellbore penetrating at least a portion of a subterranean formation.

Claim (Index 19):
The method of  claim 12  wherein the crosslinked polymer composition further comprises at least one additional crosslinker selected from the group consisting of: divinyl ether, diallyl ether, a vinyl or allyl ether of a polyglycol or polyol, allyl sucrose, ethylene glycol divinyl ether, triethylene glycol divinyl ether, diethylene glycol divinyl ether, glycerol diallyl ether, polyethylene glycol divinyl ether, propylene glycol divinyl ether, trimethylolpropane diallyl ether, pentaerythritol allyl ether, divinylbenzene, 1,3-divinylimidazolidin-2-one, divinyltetrahydropyrimidin-2(1H)-one, a diene, an allyl amine, N-vinyl-3(E)-ethylidene pyrrolidone, ethylidene bis(N-vinylpyrrolidone), and any combination thereof.
