Abstract:

Degradation in the strength of the cement is a phenomenon that occurs at a high temperature. The durability of cement is reduced after achieving maximum reliability over a period of several weeks. In oil and gas industry, the type of cement of G class and API standard is commonly used to fill the wells. At temperatures below 110oC, cement continues hydrating in order to achieve reliability in a long time, which is from several days to several years until cement is reached critical reliability. At temperatures above 110oC, crystal structures and phase shift of cement are transformed into other forms.
