Abstract The Zhengzhuang Field is a new developing coalbed methane (CBM) field in the
southern Qinshui Basin. To disclose the high interwell heterogeneity in production, we …

This study investigates the impact of carbon dioxide (CO 2) on the pore structure of coal
during CO 2 injection to understand the technical challenges associated with CO 2 …

Coal seams are typically self-sourced reservoirs. However, in certain special cases, the coal
seams also contain large amounts of external gas from other source rocks. Successful …

China's deepest coalbed methane (CBM) exploratory well was drilled to over 4000 m in the
Sichuan Basin, providing an effective database for analyzing the depth effect on methane …

The coalbed methane (CBM) resource in the southern Qinshui Basin, North China, is
abundant. Proper understanding of the geological control factors on CBM enrichment in …

The gas content and permeability of the coal reservoir are the key factors affecting coalbed
methane (CBM) productivity. To investigate the geological controls on the permeability and …

The accurate calculation of the gas content of coalbed bed methane (CBM) reservoirs is of
great significance. However, due to the weak correlation between the logging response of …

The Erlian Basin may be one of the most promising areas for low-rank coalbed methane
(CBM) in China. The Cretaceous coal-bearing strata in the Bayanhua sag contain abundant …

Gas-bearing property evaluation and main controlling factor analysis have remained a
