As an unconventional natural gas, the calorific value of coal seam gas (CSG) is equivalent to
that of natural gas. It is a high-quality, clean, and efficient green low-carbon energy source …

The stress in coal reservoir is dynamic and redistributes during coalbed methane (CBM)
production. It is abundantly evident in the literature that maximum and minimum horizontal …

Segmental-layered modeling and fine grid division methods were proposed to construct a
three-dimensional large-scale layered geologic model and reveal the mechanisms of …

Hydraulic fracturing is able to effectively enhance the permeability of coal seams and
thereby achieve the appreciable methane drainage effect. Tree-type fracturing technology is …

As a reservoir reconstruction technology, hydraulic fracturing is a key method to improve the
production of coalbed methane (CBM) wells. The CBM reservoir in eastern Yunnan, an …

Reasonable production prediction of coalbed methane (CBM) is of great significance for
improving the economic benefit of CBM reservoirs. Current prediction methods for CBM …

Water inrush results from excavation unloading and high water pressure coupling. To study
the propagation mechanisms of hydraulic fracture and failure mode under unloading …

The research on the effective utilization of deep coalbed methane (with a burial depth of
over 2500 m) within the Sinopec system is still blank, while the Daniudi gas field has …
