Silica crosslinker including boronic acid functionalities or esters thereof for treatment of subterranean formations

A method of treating a subterranean formation, comprising:

• placing a composition into a subterranean formation, the composition comprising:
• a polysaccharide viscosifier;
• and
• a crosslinker comprising a silica bonded to a crosslinking group that comprises an amine group comprising at least one of a boronic acid, an ester thereof, or a combination thereof.

A method of treating a subterranean formation, the method comprising:

• placing a composition into a subterranean formation, the composition comprising:
• a polysaccharide viscosifier;
• and
• a nanoparticle crosslinker comprising a silica bonded to a crosslinking group, the silica bonded to the crosslinking group having the structure:
• wherein:
• L1 is chosen from a bond and a substituted or unsubstituted (C1-C20)hydrocarbylene interrupted with 0, 1, 2, or 3 groups independently chosen from —O—, —S—, and substituted or unsubstituted —NH—,
• L2 is chosen from a bond and a substituted or unsubstituted (C1-C20)hydrocarbylene linker interrupted with 0, 1, 2, or 3 groups independently chosen from —O—, —S—, and substituted or unsubstituted —NH—,
• L3 is chosen from a bond, a —(NH—(C1-C5)alkyl)n- group, and a —(C1-C5)alkyl-(NH—(C1-C5)alkyl)n- group, wherein n is about 1 to about 10,000, and
• R1 and R2 are each independently selected from —H and substituted or unsubstituted (C1-C20)hydrocarbyl interrupted by 0, 1, 2, or 3 groups independently chosen from —O—, —S—, and substituted or unsubstituted —NH—, or wherein R1 and R2 together form a substituted or unsubstituted (C1-C20)hydrocarbylene interrupted by 0, 1, 2, or 3 groups independently chosen from —O—, —S—, and substituted or unsubstituted —NH—;
• and
• crosslinking the polysaccharide viscosifier with the nanoparticle crosslinker.
