Alkylated polyetheramines as clay stabilizing agents

摘要

The present disclosure provides water-based well treatment fluids for use in treating subteiTanean formations to prevent swelling and/or migration of fines. The water-based well treatment fluid contains an aqueous continuous phase, a clay stabilizing agent consisting of an alkylated polyetheramine and a weighting material. In addition to inhibiting swelling and/or migration, the water-based well treatment fluids are thermally stable, are toxicologically safe, and have exceptional handling properties.
