Gas Flow Behavior of Nanoscale Pores in Shale Gas Reservoirs

open access: yes, 2017
The gas transport in shale nanopores is always one of the major concerns in terms of the development of shale gas reservoirs. In this study, the gas flow regimes in shale nanopores were classified and analyzed according to Knudsen number.

Shale gas investigations in Denmark: Lower Palaeozoic shales on Bornholm [PDF]

open access: yesGeological Survey of Denmark and Greenland Bulletin, 2011
The Cambrian to Lower Silurian succession in Denmark is mostly composed of organic-rich black shales that were deposited in an epicontinental sea during a period of high global sea level (Haq & Schutter 2008). The mid-Cambrian to early Ordovician Alum Shale was intensively studied in the 1980s for its source-rock properties (e.g.

Carbon‐Embedded Fe‐Cu Composite Oxide Nanoparticles Derived From Spindle‐Shaped Bimetallic MOFs for Selective Oxidation of Methane

open access: yesCarbon and Hydrogen, EarlyView.
Fe3Cu1/C (CuFe5O8) was synthesized by high‐temperature carbonization of FexCuyBDC MOF, which exhibited excellent catalytic performance for methane selective oxidation at 80°C. The synergistic effect between Cu and Fe in the derived Fe3Cu1/C (CuFe5O8) composite oxide inhibits deep oxidation compare to Fe/C (Fe3O4), and the reaction proceeds via a free ...

Challenges of Bio‐Syngas Conversion to High‐Value‐Added Liquid Chemicals and Fuels via COx Hydrogenation

open access: yesCarbon Energy, EarlyView.
Converting biomass‐derived syngas into value‐added fuels and chemicals offers a promising route toward carbon neutrality, yet unfavorable H2/COx ratios, elevated CO2 levels, and trace impurities pose persistent obstacles. This review examines strategies spanning syngas conditioning, impurity‐tolerant catalyst development, and integrated process design,

Lattice Boltzmann modeling of the coupled imbibition-flowback behavior in a 3D shale pore structure under reservoir condition

open access: yesFrontiers in Earth Science, 2023
Imbibition and flowback of fracturing fluid usually occur in the shale matrix after hydraulic fracturing, which significantly impacts shale gas production and environmental protection. The rocks of deep shale gas reservoirs are under high-temperature and
