Gelled acidizer composition |
| abstract |
What is provided herein is a gelled acidizer composition which comprises an aqueous acid solution and a gelling agent therein which is a strongly swellable, moderately crosslinked polyvinylpyrrolidone polymers in the form of fine, white powders characterized by (a) an aqueous swelling parameter defined by its gel volume of about 15 to 150 ml/g of polymer and (b) a Brookfield viscosity in 5% aqueous solution of at least about 10,000 cps. |
