TREATMENT FLUIDS COMPRISING A STABILIZING COMPOUND HAVING QUATERNIZED AMINE GROUPS AND METHODS FOR USE THEREOF

摘要

Methods for mitigating precipitation during matrix acidizing of a subterranean formation. The methods generally comprise introducing a treatment fluid into a subterranean formation. The treatment fluid comprises a chelating agent; a hydrofluoric acid source; and a stabilizing compound. The stabilizing compound has two or more quaternized amine groups. In some cases the treatment fluid further comprises alkali metal ions.
