Abstract
Nano-level evaluation of kerogen-rich reservoir rock is described. A nano-scale beam is formed from kerogen-rich reservoir rock. The nano-scale beam includes reservoir rock and kerogen having polymeric properties. A mechanical experiment is performed on the nano-scale beam. The mechanical experiment is imaged using a scanning electron microscope (SEM) or a transmission electron microscope (TEM). A material parameter of the kerogen in the nano-scale beam is determined based on the mechanical experiment and images obtained responsive to the imaging.
Claims5
A method comprising:
- forming a beam from a cement mixture comprising cement and a polymer, wherein a maximum dimension of the beam is at most 1000 micrometer (μm);
- performing a mechanical experiment on the beam, wherein the mechanical experiment comprises a tension test or a compression test;
- imaging the mechanical experiment using a scanning electron microscope (SEM) or a transmission electron microscope (TEM);
- and
- determining a material parameter of the polymer in the beam based on results of the mechanical experiment and images obtained responsive to the imaging;
- before forming the beam, treating the cement mixture with an organic additive configured to alter properties of the polymer in the cement mixture;
- and
- determining an effect of organic additive on the polymer in the mixture based on the material parameter of the polymer in the beam.
