Abstract
This disclosure relates to compositions including a poly-alkene maleic anhydride copolymer, a PEG, and a crosslinker selected from an ethyleneamine, a benzenetricarboxylic acid, a benzimidazole, and combinations thereof. The poly-alkene maleic anhydride copolymer includes repeat units I and II: where R1, R1′, R2, and R2′ are each independently selected from —H and —(C1-C5)alkyl. The disclosure also provides methods of treating a subterranean formation or cement construction using the compositions.

A method of treating a subterranean formation or cement construction comprising:
- providing to the subterranean formation or cement construction a liquid resin composition comprising:
- a poly-alkene maleic anhydride copolymer comprising:
- repeat units I and II:
- wherein R1, R1′, R2, and R2′ are each independently selected from —H and —(C1-C5)alkyl;
- a polyethylene glycol (PEG) having a molecular weight of about 5000 kDa to about 50,000 kDa;
- and
- a crosslinker selected from an ethyleneamine, a benzenetricarboxylic acid, a benzimidazole, and combinations thereof;
- and
- crosslinking the composition to form a sealant.
