A study of reaction of alkaline chemicals with minerals constituting reservoir rock is presented. Static tests were conducted using high concentrations of sodium hydroxide and orthosilicate solutions and minerals, namely, montmorillonite, kaolinite, illite, and quartz sand. The reaction time varied from 10 minutes to 2 months. Solutions were analyzed for hydroxide, (Si) and (Al), and solids were analyzed by X-ray diffraction and other spectroscopic techniques. The loss of useful alkalinity was the highest with kaolinite and the least with quartz sand, especially for high alkali concentration or temperature. A detailed study of kaolinite-alkali reaction kinetics and quartz-alkali equilibrium is presented.
