A formation control additive is utilized in stimulation fluids to minimize formation permeability damage as a result of formation contact by the stimulation fluid. The formation control additive can comprise N-alkypyridinium halides, N,N,N-trialkylphenylammonium halides, N,N,N-trialkylbenzylammonium halides, N,N-dialkylmorpholinium halides, alkyl quaternary ammonium salt of 2 mole oligomer of epihalohydrin wherein the alkyl radical is selected from the group of methyl, ethyl, propyl and butyl radicals and compounds of the general formula: <IMAGE> wherein R is independently a methyl, ethyl, propyl or butyl radical and X is a compatible anion.
