The quality of oil and geothermal well cement is very important in optimizing the rate of production. Good bonding between cement with casing and between cement and rock formation is essential for effective zone isolation, hence the additive should be added in order to improve the characteristics of standard cement. <br /> <br /> <br /> The purposes of this research are to know the effect of the addition of expanding material pure-burnt MgO and CaO on the value of shear bond strength and compressive strength of API class G cement in high pressure and high temperature. <br /> <br /> <br /> The method applied on this research was by evaluating the data taken from simulator which was simulate with 100-250oC temperature and 2000 psi pressure. <br /> <br /> <br /> The conclusions taken according to the results are: The addition of CaO and MgO will increase the shear bond strength and the compressive strength on specific condition up to 200oC temperature. The addition will be ineffective for the 250oC condition. The cement strength behavior will be also affected by the addition of curing time. <br /> <br /> <br /> This expanding cement needs some further research for the compatibility when combined with other additives, especially extender additive which could reduce its density value.
