Patent ID: 7703529

Claim:
A method of treating a producing well by removing solids from a wellbore, the method comprising the steps of: (a) placing a first, polymer-containing fluid in the wellbore, wherein the polymer comprises a polymer selected from the group consisting of carrageenan, alginate, gellan, konjacmannan, xanthan or guar; (b) placing a second, viscosifying fluid in the wellbore, wherein the second, viscosifying fluid increases the viscosity of said first fluid; (c) forming a viscous gel in the wellbore which entrains the solids material; and, (d) removing the viscous gel and the entrained solids material from the wellbore; wherein the first fluid or the second fluid further comprises fibers selected from the group consisting of polypropylene, polyethylene terephthalate, novoloid, and fiberglass materials, and wherein the first fluid and the second fluid are placed into the wellbore before a gel is formed.
