Unconventional Gas in the Benelux: Cautious Attitudes and Regional Interplay [PDF]

, 2014
The three countries of the Benelux are often overlooked in Europe’s current unconventional gas debate. But the Netherlands, Belgium and Luxembourg all possess considerable shale gas resources, and major energy companies have already taken an interest. So

Experimental Study on the Mechanical Damage and Permeability Evolution of Coal With Different Moisture Contents Under Supercritical Carbon Dioxide Conditions

Energy Science &Engineering, Volume 13, Issue 5, Page 2375-2388, May 2025.
ABSTRACT Using a self‐developed supercritical carbon dioxide (CO2) soaking system, the damage mechanisms and cracking characteristics of coal due to supercritical CO2 under the coupling of high‐temperature, high‐pressure, water, and the seepage evolution law and failure mode of coal bodies were revealed.

Evolution law of pulsating seepage and thermal deformation by injecting high‐temperature steam into coal for thermal coalbed methane recovery

Deep Underground Science and Engineering, Volume 4, Issue 1, Page 119-131, March 2025.
A new phenomenon of pulsation of steam permeability is discovered. The permeability of high‐temperature steam in coal shows a periodic pulsation pattern with an increase in the injection time. A two‐phase flow theory of gas–liquid is adopted to elucidate the mechanism of pulsating seepage of steam.

Geochemical Constraints on the Generation of Coalbed Methane in the Weizhou Area, South‐Central Ningxia, NW China: Insights From Stable Isotopes and Organic Petrology

Geofluids, Volume 2025, Issue 1, 2025.
Amid growing global clean energy demand, coalbed methane (CBM) in the coal‐rich Weizhou area holds great development value. This study explores Weizhou CBM′s geochemical traits and genesis via analyzing gas compositions (Shanxi and Taiyuan Formations), stable isotopic distributions (δ13C1, δD, δ13CO2, and δ15N), and their burial depth variations ...

Study on the CO2 Adsorptive Sequestration Characteristics and Evaluation Model of High‐Rank Coal Reservoirs in Situ Underground

International Journal of Chemical Engineering, Volume 2025, Issue 1, 2025.
Geological CO2 sequestration is currently one of the main effective pathways to achieve industrial carbon reduction. The adsorption of CO2 by coal is a unique storage method for carbon sequestration in underground coal reservoirs. This study conducts isothermal adsorption experiments on high‐rank coal reservoirs with strong gas adsorption capacity in ...
