Shale rocks play an essential role in petroleum exploration and production because they can occur either as source rocks or caprocks depending on its mineralogical composition and microstructures. Utilization of shale in carbon capture and storage requires these rocks be resilient to the formation of fractures; while extraction of hydrocarbons from shale rocks relies on the opposite premise that permeability can be significantly enhanced by the induced hydraulic fractures. Failure of the shale starts with deterioration at micro/nanoscale, the structural features and properties at the micro/nanoscale can significantly impact the durability performance of these materials at the macroscale. This paper presented a method using nano- indentation for examining the properties of constituent phases independently of each other in composite material microstructures, thus, the effect of each component on the microstructure and bulk mechanical properties can be better understood.
