| Abstract Scope |
To develop hydrocarbon recovery with heating methods, it is essential to understand the nature of the thermal and microstructural behaviors of shale in both oxidative and reductive atmospheres. Here, we report our recent studies on the thermal and microstructural properties of a shale sample from the Marcellus Formation, Pennsylvania. Employing in situ XRD, in situ DRIFTS, small-angle neutron scattering (SANS), integrated TG-DSC-MS, and TEM, we were able to correlate the naturally heterogeneous and complex chemistry of the Marcellus shale with its mineralogical and thermal stability up to 900 °C in both air and inert gas. The thermal decomposition of organic and inorganic phases led to systematic evolutions in the shale characteristics. The decompositions of kerogen and minerals resulted in microscopic cracks and accessible channels/pores within the shale, which were probed and elucidated with SANS. This study enables insights into the thermal pyrolysis process of shale for enhanced hydrocarbon recovery. |
