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 ...

The primary controlling factors of the occurrence state of deep high-rank coalbed methane in eastern Ordos Basin

Frontiers in Earth Science
Introduction: This study investigates the key controlling factors of the occurrence state of deep coalbed methane (CBM). CBM is an abundant energy resource in China, particularly in deep coal seams.

Occurrence and Potential for Coalbed Methane Extraction in the Depocenter Area of the Upper Silesian Coal Basin (Poland) in the Context of Selected Geological Factors

Energies
Coalbed methane (CBM) is the only unconventional gas in Poland with estimated recoverable resources. The prospects for developing deep CBM have been explored in recent years by drilling deep exploration wells within the depocenter of the Upper Silesian ...

Coalbed methane in the Upper Silesian Coal Basin [PDF]

, 2008
Coalbed methane (CBM) should be considered complementary to conventional gas. CBM resource is estimated at 28.5 billion m3 for active coal mines in the Upper Silesian Coal Basin (USCB) and 124.5 billion m3 for the prospective areas outside of coal mines.

Exploration and development process of coalbed methane in eastern margin of Ordos Basin and its enlightenment

, 2022
The buried depth of coal seam in the eastern margin of Ordos Basin changes greatly, and the characteristics of coalbed methane reservoir formation and reservoir reconstruction methods vary greatly with different buried depths. At present, coalbed methane
