ABSTRACT:
A method for conditioning a flow of hot geothermal brine or aqueous liquid to reduce scale formation by pH-sensitive, dissolved materials includes injecting into the flow of brine or liquid an anhydrous, halogenated acid precursor which hydrolyzes in the brine or liquid to form a hydrohalic acid. The acid precursor, which may be tetrachloromethane, is preferably injected into an extraction well at the vicinity of the producing formation at a rate reducing the pH of the brine or liquid about one pH unit, or to about 3.5, near the injection point. The method also provides for increasing, if necessary, the acid precursor hydrolysis rate in the brine or liquid by atomizing the injected acid precursor with a pressurized fluid, preferably gaseous nitrogen.
