摘要：
Examples of nano-level evaluation of kerogen-rich reservoir rock are described. A micro-scale beam is formed from kerogen-rich reservoir rock. The beam has reservoir rock and kerogen, which has polymeric properties. A maximum dimension of the micro-scale beam is at most 1000 micrometers. A mechanical experiment that includes a tension test or a compression test is performed on the micro-scale beam. The mechanical experiment is imaged using a scanning electron microscope (SEM). A material parameter of the kerogen in the micro-scale beam is determined based on results of the mechanical experiment and images obtained responsive to the imaging. The material parameter includes a behavior of the kerogen in response to the mechanical experiment. The behavior of the kerogen can be used to determine, among other things, the energy required to break kerogen in a kerogen-rich shale to improve hydraulic fracturing efficiency.
