    Abstract: A rock sample is nano-indented from a surface of the rock sample to a specified depth less than a thickness of the rock sample. While nano-indenting, multiple depths from the surface to the specified depth and multiple loads applied to the sample are measured. From the multiple loads and the multiple depths, a change in load over a specified depth is determined, using which an energy associated with nano-indenting rock sample is determined. From a Scanning Electron Microscope (SEM) image of the nano-indented rock sample, an indentation volume is determined responsive to nano-indenting, and, using the volume, an energy density is determined. It is determined that the energy density associated with the rock sample is substantially equal to energy density of a portion of a subterranean zone in a hydrocarbon reservoir. In response, the physical properties of the rock sample are assigned to the portion of the subterranean zone.

    Abstract: Controlled manufacture and nano-level evaluation of kerogen-rich reservoir rock can be implemented as a method. A clay mineral found in kerogen-rich shale is selected. An organic component found in kerogen-rich shale is selected. Multiple concentrations of the clay mineral are selected. Multiple concentrations of the organic component are selected. Multiple kerogen-rich shale samples are fabricated. Each sample includes a first concentration of the multiple concentrations of the clay mineral and a second concentration of the multiple concentrations of the organic component. A microscale beam is formed of each fabricated sample. A maximum dimension of the microscale beam is at most 100 µm. A mechanical experiment is performed on the microscale beam of each fabricated sample. The mechanical experiment includes a tension test or a compression test. The mechanical experiment on the microscale beam of each fabricated sample is imaged using a scanning electron microscope or a transmission electron microscope. A material parameter of the microscale beam of each fabricated sample is determined based on results of the mechanical experiment and images obtained responsive to the imaging. Effects of the clay mineral on the kerogen-rich shale are determined based on the material parameter of the microscale beam of each fabricated sample.

    Abstract: Provided are systems and methods for determining fracture toughness of a subsurface geologic formation. Embodiments include collecting (from drilling fluid circulated into a wellbore during a drilling operation) a drill cutting generated by a drill bit cutting into a subsurface formation, preparing (from the drill cutting) a drill cutting specimen comprising a miniature single edge notch beam (SENB) having a specified length in the range of 1 millimeter (mm) to 100 mm, conducting a three -point bend testing of the drill cutting specimen to generate load-displacement measurements for the drill cutting specimen, and determining (based on the load-displacement measurements for the drill cutting specimen) a fracture toughness of the subsurface formation.

    Abstract: Nano-indentation test to determine mechanical properties of reservoir rock can be implemented as multi-stage or single-stage tests. An experimental nano-indentation test (multi-stage or single-stage) is performed on a solid sample. A numerical nano-indentation test (multi-stage or single-stage) is performed on a numerical model of the solid sample. One or more experimental force-displacement curves obtained in response to performing the experimental nano-indentation test and one or more numerical force-displacement curves obtained in response to performing the numerical test are compared. Multiple mechanical properties of the solid sample are determined based on a result of the comparing
