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

A Novel Energy-Efficient Pyrolysis Process: Self-pyrolysis of Oil Shale Triggered by Topochemical Heat in a Horizontal Fixed Bed

Figure 5: Description of the main phenomena occurring during the propagation of the self-pyrolysis front.

The results show that the self-pyrolysis of oil shale can be achieved with the proposed method without any need for external heat. The results also verify that fractured oil shale may be more suitable for underground retorting. Moreover, the gas and liquid products from this method were characterised, and a

Selecting Oil Wells for Hydraulic Fracturing: A Comparison between Genetic-Fuzzy and Neuro Fuzzy Systems

Selecting Oil Wells for Hydraulic Fracturing A Comparison between Genetic-Fuzzy and Neuro Fuzzy Systems

Abstract Hydraulic fracturing is widely used to increase oil well production and to reduce formation damage. Reservoir studies and engineering analyses are carried out to select the wells for this kind of operation. As the reservoir parameters have some diffuse characteristics, Fuzzy Inference Systems (FIS) have been tested for these selection

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.
