Abstract

A method of preventing plastering or agglomeration and inhibiting the swelling of debris or formation shales in an aqueous medium, characterized by treating said medium with a polyvalent metal ion, the ion being completed by a complex-forming component that is acetic, citric acid, formic, lactic, oxalic or tartaric, their alkali metal or ammonium metal salts or mixtures thereof, the medium under treatment having a pH at least as high as 7.0.
