Zusammenfassung:	The method of using soap as a fluid loss additive in the hydraulic fracturing treatment of oil and gas wells includes choosing a soap having a titre value which will insure that the soap will dissolve and liquify at the formation temperature in the area where fluid loss is to be reduced. The formation temperature in this area is reduced to an extent where the soap will not liquify, while the soap is introduced into the area under pressure, and this lower temperature is maintained while a fracturing or cementing process is carried out. Subsequently, the temperature in the area where fluid loss is to be reduced is permitted to rise and liquify the soap which is then removed from the well.
