Quantitative Analysis of Gas Occurrence States and Its Controlling Factors in Deep CBM Reservoirs: An Integrated Model With Application in Linxing Block

Geofluids, Volume 2025, Issue 1, 2025.
Deep coalbed methane (CBM) is a crucial resource for ensuring energy security. Despite some successful localized deep CBM developments, the unclear understanding of gas content and gas occurrence state remains a key obstacle to the comprehensive development of deep CBM.

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 ...
