Abstract

Solid-supported crosslinkers for treatment of a subterranean formation. A method of treating a subterranean formation includes placing in the subterranean formation a composition that includes a solid-supported crosslinker. The solid-supported crosslinker includes a supporting solid, and a crosslinker supported on the supporting solid.

First claim

What is claimed is:

1. A method of treating a subterranean formation, the method comprising:
obtaining or providing above the surface of the subterranean formation a composition comprising a solid-supported crosslinker, the solid-supported crosslinker comprising
a particulate supporting solid that is a sol-gel technique-formed material selected from the group consisting of silica, a borate, magnesium oxide, and a combination thereof, the particulate supporting solid having a particle size of about 0.1 mm to about 20 mm, and
a crosslinker supported on the particulate supporting solid; and

placing in the subterranean formation the composition obtained or provided above the surface of the subterranean formation comprising the solid-supported crosslinker;
wherein the composition further corn s a crosslinkable polymer, and
wherein the crosslinker supported on the particulate supporting solid has a greater or lower reactivity with the crosslinkable polymer than a corresponding crosslinker that is not supported by the supporting solid.

2. The method of claim 1 , wherein the placing of the composition in the subterranean formation comprises fracturing at least part of the subterranean formation to form at least one subterranean fracture.

3. The method of claim 1 , wherein the composition is placed in the subterranean formation in at least one of a fracture and at least a part of an area surrounding a fracture.

4. The method of claim 1 , wherein the crosslinkable polymer comprises a linear polysaccharide.

5. The method of claim 1 , wherein the crosslinkable polymer comprises at least one of poly(acrylic acid) or esters thereof, poly(vinyl acetate), poly(vinyl alcohol), poly(ethylene glycol), poly(vinyl pyrrolidone), polyacrylamide, poly (hydroxyethyl methacrylate), starch, tamarind, tragacanth, gum ghatti, gum arabic, locust bean gum, cellulose, hydroxyethyl cellulose, carboxymethyl hydroxyethyl cellulose, hydroxypropyl cellulose, methyl hydroxyl ethyl cellulose, guar gum, hydroxypropyl guar, carboxy methyl guar, and carboxymethyl hydroxylpropyl guar.

6. The method of claim 1 , wherein the method further comprises crosslinking the crosslinkable polymer to give a crosslinked polymer.

7. The method of claim 6 , wherein at least part of the crosslinking comprises a chemical reaction between the crosslinker supported on the particulate supporting solid and the crosslinkable polymer.

8. The method of claim 6 , wherein the method further comprises separating the particulate supporting solid and the crosslinker supported on the particulate supporting solid to give an unsupported crosslinker, wherein at least part of the crosslinking comprises a chemical reaction between the crosslinkable polymer and the unsupported crosslinker.

9. The method of claim 6 , further comprising triggering the crosslinking.

10. The method of claim 1 , wherein the particulate supporting solid comprises a proppant.

11. The method of claim 1 , wherein the particulate supporting solid comprises at least one of sand, gravel, clay, silica, an inorganic material, and an organic polymer.

12. The method of claim 1 , wherein the crosslinker supported on the particulate supporting solid comprises at least one of chromium, aluminum, antimony, zirconium, titanium, calcium, boron, iron, silicon, copper, zinc, and magnesium.

13. The method of claim 1 , wherein the crosslinker supported on the particulate supporting solid comprises at least one of boric acid, borax, ferric chloride, disodium octaborate tetrahydrate, sodium diborate, a pentaborate, ulexite, colemanite, magnesium oxide, zirconium lactate, zirconium triethanol amine, zirconium lactate triethanol amine, zirconium carbonate, zirconium acetylacetonate, zirconium malate, zirconium citrate, zirconium diisopropylamine lactate, zirconium glycolate, zirconium triethanol amine glycolate, zirconium lactate glycolate, titanium lactate, titanium malate, titanium citrate, titanium ammonium lactate, titanium triethanolamine, titanium acetylacetonate, aluminum lactate, and aluminum citrate.

14. The method of claim 1 , wherein the solid-supported crosslinker has a particle size of about 0.1 mm to about 50 mm.

15. The method of claim 1 , wherein the solid-supported crosslinker comprises a degradable coating that at least partially coats an outer surface of the solid-supported crosslinker.

16. The method of claim 1 , further comprising combining the composition with an aqueous or oil-based fluid comprising a drilling fluid, stimulation fluid, fracturing fluid, spotting fluid, clean-up fluid, production fluid, completion fluid, remedial treatment fluid, abandonment fluid, pill, acidizing fluid, cementing fluid, packer fluid, or a combination thereof, to form a mixture, wherein the placing of the composition in the subterranean formation comprises placing the mixture in the subterranean formation.

17. A method of treating a subterranean formation, the method comprising:
obtaining or providing above the surface of the subterranean formation a composition comprising
a solid-supported crosslinker comprising
a particulate supporting solid comprising a proppant, wherein the particulate supporting solid is a sol-gel technique-formed material selected from the group consisting of silica, a borate, and magnesium oxide, the particulate supporting solid having a particle size of about 0.1 mm to about 20 mm; and
a crosslinker supported on the particulate supporting solid, the crosslinker comprising at least one of boric acid, borax, zirconium lactate, zirconium triethanol amine, zirconium lactate triethanolamine, zirconium carbonate, zirconium acetylacetonate, zirconium mal ate, zirconium citrate, zirconium diisopropylamine lactate, zirconium glycolate, zirconium triethanol amine glycolate, and zirconium lactate glycolate; and

a crosslinkable polymer comprising at least one of cellulose, carboxymethyl cellulose, hydroxyethyl cellulose, carboxymethyl hydroxyethyl cellulose, hydroxypropyl cellulose, methyl hydroxyl ethyl cellulose, guar, hydroxypropyl guar, carboxy methyl guar, and carboxymethyl hydroxylpropyl guar;

placing in the subterranean formation the composition obtained or provided above the subterranean formation comprising the solid-supported crosslinker,
crosslinking the crosslinkable polymer with the crosslinker, and
wherein the crosslinker supported on the particulate supporting solid support has a greater or lower reactivity with the crosslinkable polymer than a corresponding crosslinker that is not supported by the supporting solid.

18. A system comprising:
a composition comprising a solid-supported crosslinker, the solid-supported crosslinker comprising
