Abstract:
1. A method for pre-saturating a high permeability subterranean formation comprising: injecting into a wellbore in a subterranean formation having a permeability of at least 100 millidarcies (md) (10 pumping the aqueous viscoelastic treating fluid against the high permeability subterranean formation; stop pumping the aqueous viscoelastic treating fluid against the high permeability subterranean formation to permit the aqueous viscoelastic treating fluid to be at least partially absorbed into pores of the high permeability subterranean formation for a time interval ranging from about 5 to about 30 minutes; and injecting a second treating fluid into the wellbore for a treatment operation, in the absence of acetic acid, formic acid, hydrochloric acid, hydrofluoric acid.
