Abstract
A process for treating a subterranean earth formation includes the step of introducing an acidizing treatment fluid comprising a monovalent salt of monochloroacetic acid into the subterranean earth formation in the presence of at least one bromide or iodide salt or salt precursor, wherein the at least one bromide or iodide salt or salt precursor is introduced into the subterranean earth formation in an amount of from about 0.3 to about 10 wt %, based on the total weight of the acidizing treatment fluid. The acidizing treatment fluid itself includes the monovalent salt of monochloroacetic acid, the at least one bromide or iodide salt or salt precursor, and optionally an element to suppress precipitation of calcium glycolate and/or at least one acid.
