Oilwell cements and calcium hydroxide formation

Caveny, Bill

Calcium hydroxide formation and reactions are an important mechanism during the hydration process of Portland cements. This paper presents a brief study of some causes and effects of calcium hydroxide in oilwell cements as they undergo hydration in varying conditions of temperature and pressure relative to the downhole environments of oilwells. Light microscopy and electron microscopy methods utilizing cryogenics, environmental scanning electron microscopy (ESEM), and high-vacuum systems are all used in examining the formation of calcium hydroxide as the cement hydrates under varying conditions.
