Solvents and mutual solvents have been used for numerous years as stimulation treatments or as components of stimulation treatment packages. This paper presents the results of field case histories of stimulation treatments using a unique combination of selected solvents and mutual solvents to remove hydrocarbon based formation damage. Treatment with this chemical has been effective in removal of multi-constituent hydrocarbon and hydrocarbon/water caused damage. The removal of this damage in producing wells provides increased production at rates and lifetimes exceeding those obtained by conventional solvent or solvent/acid treatments, and hot oiling treatments.
