The thick and steeply inclined coal seams of the Junggar Basin of Xinjiang, China, are
unique with dip angles generally> 50° but over the range 0°–85°. Initial and evolving …

In mixed genesis gas (MGG) areas, varying proportions of microbial and thermogenic gases
lead to more intricate geochemical composition distributions, but the critical geochemical …

This paper mainly focused on the genesis of coalbed methane (CBM), CO 2 origin and the
CBM accumulation mechanism in the southern Junggar Basin using a combination of …

Accurate characterization of the compressibility of pores and fractures in coal reservoirs is of
great significance for predicting permeability and for optimizing the production of coalbed …

Gas co-production has been touted to be a cost-effective way to increase the recoverable
coal-bed methane (CBM) resource in multiple coal seams. However, co-production in the …

Nitrogen injection is an effective way to improve coalbed methane (CBM) recovery, but there
are few studies of the regularity of fluid flow during nitrogen injection. To study the flow of …

The southern Junggar Basin, Xinjiang, has abundant coalbed methane (CBM) resources.
Currently, the Baiyang River development pilot test area (BYR block for short) in the Fukang …

Coal structure is an important parameter affecting coalbed methane (CBM) production and
reservoir stimulation. It shows significant heterogeneity in the vertical direction of the coal …

The permeability of the coal reservoir is affected by the stress caused by water production
and matrix shrinkage caused by methane desorption, and its change rate is mainly affected …

In the present study, three CBM blocks in the central and southern Qinshui Basin, China,
including Fanzhuang, Zhengzhuang, and Changzhi blocks, were selected. Combined with …
