Organic acid system for high temperature acidizing
Dicarboxylic acids are useful in acidizing subterranean formations to improve their permeability, particularly at elevated temperature, e.g. between about 200&deg; F. (92&deg; C.) and about 400&deg; F. (204&deg; C.). Particularly suitable dicarboxylic acids include, but are not necessarily limited to, succinic acid, glutaric acid, adipic acid, and mixtures thereof.
