Abstract

A process for stimulating a hydrocarbon containing underground formation comprising siliceous material, by treating the formation with an aqueous solution in which a mud acid is generated from a fluoride salt and a relatively slowly-reactive acid-yielding material formed by chloro-carboxylate material from which chlorine is relatively easily hydrolyzable.
