Abstract

The present disclosure relates to systems and methods for using aldehydes as a catalyst for oxidative breakers. An embodiment of the present disclosure is a method comprising: providing a treatment fluid that comprises: an aqueous base fluid, a polymeric gelling agent, a breaker that comprises an oxidative salt, and a catalyst that comprises an aldehyde; allowing the breaker to interact with the polymeric gelling agent; and allowing the viscosity of the treatment fluid to reduce.

First claim

What is claimed is:

1. A method comprising:
providing a treatment fluid that consists essentially of:
an aqueous base fluid,
a polymeric gelling agent,
a breaker that comprises at least one oxidative salt selected from the group consisting of: a chlorite salt, a chlorate salt, a perchlorate salt, and any combination thereof, wherein the breaker is present in the treatment fluid in a range of about 0.00625% to about 0.25% weight by weight,
a catalyst that comprises at least one aldehyde selected from the group consisting of: glutaraldehyde, propionaldehyde, and any combination thereof, wherein the catalyst is present in the treatment fluid in a range of about 0.0025% to about 0.05% weight by weight;

allowing the breaker to interact with the polymeric gelling agent in the presence of the catalyst at a temperature in a range of about 140° F. to about 200° F.; and
allowing the viscosity of the treatment fluid to break in less than about 60 minutes.

2. The method of claim 1 wherein the aldehyde is glutaraldehyde.

3. The method of claim 1 wherein the polymeric gelling agent comprises at least one polymer selected from the group consisting of: alginate, chitosan, cyclosophoran, dextran, galactoglucopolysaccharide, gellan, glucuronan, N-acetyl-glucosamine, N-acetyl-heparosan, hyaluronic acid, indicant, kefiran, lentinan, levan, mauran, pullulan, scleroglucan, schizophyllan, stewartan, succinoglycan, xanthan, welan, starch, tamarind, tragacanth, guar gum, hydroxypropyl guar, carboxy methyl guar, carboxymethyl hydroxylpropyl guar, gum ghatti, gum arabic, locust bean gum, cellulose, carboxymethyl cellulose, hydroxyethyl cellulose, carboxymethyl hydroxyethyl cellulose, hydroxypropyl cellulose, methyl hydroxyl ethyl cellulose, acrylamide, acrylic acid, 2-acrylamido-2-methylpropane sulfonic acid, N,N-dimethylacrylamide, vinyl sulfonic acid, N-vinyl acetamide, N-vinyl formamide, itaconic acid, methacrylic acid, an acrylic acid ester, a methacrylic acid ester, quaternized aminoalkyl acrylate, poly(vinyl acetate), poly(vinyl alcohol), poly(ethylene glycol), and poly(vinyl pyrrolidone), and any combination thereof.

4. The method of claim 1 wherein at least a portion of the polymeric gelling agent is crosslinked by a crosslinking reaction comprising a crosslinking agent.

5. The method of claim 4 wherein the crosslinking agent comprises at least one crosslinking agent selected from the group consisting of: boric acid, disodium octaborate tetrahydrate, sodium diborate, pentaborates, ulexite, colemanite, zirconium lactate, zirconium lactate triethanolamine, zirconium carbonate, zirconium acetylacetonate, zirconium malate, zirconium citrate, zirconium diisopropylamine lactate, zirconium glycolate, titanium lactate, zirconium triethanol amine glycolate, zirconium lactate glycolate, zirconium triethanol amine, titanium malate, titanium citrate, titanium ammonium lactate, titanium triethanolamine, titanium acetylacetonate, aluminum lactate, aluminum citrate, an antimony compound, a chromium compound, an iron compound, any derivative thereof, and any combination thereof.
