Abstract
The present invention generally relates to methods for removing deposits in an oil or gas well by contacting the annular fluid in a batch-wise method with an effective amount of a composition comprising a water-soluble copolymer. These methods are advantageous because they can be used as needed to improve well operation. The methods use a water-soluble copolymer comprised of an acrylamide monomer and one or more cationic monomer.
