Microstructural imaging and characterization of oil shale before and after pyrolysis

Fig. 13. (A) Porosity of 10 oil shale samples after pyrolysis at 500 °C, (B) – (D). 2-D gray scale images for organic-rich, organic-mixed and organic-lean regions respectively. (E) – (G) 3-D rendered volumes with the pore space visualized in blue.

Abstract The microstructural evaluation of oil shale is challenging which demands the use of several complementary methods. In particular, an improved insight into the pore network structure and connectivity before, during, and after oil shale pyrolysis is critical to understanding hydrocarbon flow behavior and enhancing recovery. In this experimental study, bulk

Dynamic imaging of oil shale pyrolysis using synchrotron X-ray microtomography

We image the time evolution of the pore and microfracture networks during oil shale pyrolysis using synchrotron X-ray microtomography. Immature Green River (Mahogany Zone) shale samples were thermally matured under vacuum conditions at temperatures up to 500°C while being periodically imaged with a 2 μm voxel size.
