Treatment fluids comprising viscosifying agents and methods of using the same
View Patent ↗Methods include introducing a treatment fluid into a wellbore penetrating a subterranean formation, the treatment fluid including a polymer gel comprising a water-soluble polymer, a biocidal agent in an amount sufficient to viscosify the treatment fluid, and an aqueous base fluid.
1. A method comprising:
(a) mixing about 1,000 ppm to about 5,000 ppm hydroxypropyl guar with an aqueous base fluid comprising about 400 ppm to about 1200 ppm peracetic acid (PAA), thereby making a viscosified composition that immediately following the mixing has a viscosity that is greater than a corresponding composition that does not include PAA in the aqueous base fluid, and
(b) introducing a treatment fluid comprising the viscosified composition into a wellbore penetrating a subterranean formation.
2. The method of claim 1 , wherein the treatment fluid is a fracturing fluid.
3. The method of claim 1 , wherein the treatment fluid is a polymer flooding fluid.
4. The method of claim 1 , wherein the treatment fluid is a diverting fluid.
5. The method of claim 1 , wherein the treatment fluid is a gravel pack fluid.
6. The method of claim 1 , wherein the treatment fluid is a fluid loss control fluid.
7. The method of claim 1 , wherein the treatment fluid is a perforating fluid.
8. The method of claim 1 , wherein the aqueous base fluid comprises production water.
9. The method of claim 2 , wherein the aqueous base fluid comprises production water.
10. The method of claim 3 , wherein the aqueous base fluid comprises production water.
11. The method of claim 4 , wherein the aqueous base fluid comprises production water.
