Electronic Theses and Dissertations
Studies of the effects of polishing techniques, scale of nanoindentation, and petrophysical properties were conducted on both Woodford and Tuscaloosa Marine Shale. Polishing procedures include both an in-house developed, mechanical sample preparation protocol as well as ion beam milling. The elastic modulus and hardness of each mechanically polished sample was found to have larger value than those that were ion-milled. Additionally, at low loads, the samples resulted in having high standard deviation. This high deviation was found to be significantly reduced by testing at higher loads. The variations in results between mechanically polished and ion beam milled samples is believed …
