Abstract
During the process of CO2 sequestration the wellbore undergoes under a variety of temperature changes, from the high temperatures of the subsurface to the low temperatures of supercritical CO2. These large changes in temperature will cause a change in the mechanical properties of near wellbore materials, such as the steel casing and the oil well cement. While the properties of steel are quite well known, the properties of oil well cement are not, especially with changing temperature. To understand the effects that CO2 sequestration has on the near wellbore environment, the properties of cement must be obtained at a variety of different temperatures. Obtaining mechanical properties, such as Poisson’s Ratio, Bulk Modulus, Young’s Modulus, and Shear Modulus, can be base on P and S wave velocities through the specimens. In addition when the temperature changes the cement will expand and contract causing a difference in length determined by the linear thermal expansion coefficient which could cause complications in the wellbore, this too must be obtained to completely understand the effects that CO2 sequestration will have on the near wellbore environment.
Biography
Benjamin is a junior in petroleum engineering at Missouri University of Science and Technology. He has been studying the effects of thermal loading on cement for two years. His first year was part of an OURE and his second year was as a research assistant. He is also a member of Tau Beta Pi, Sigma Gamma Epsilon, and the Society of Petroleum Engineers.
