As with other reservoir types permeability is a key controlling factor for gas migration in
coalbed methane reservoirs. The absolute permeability of coal reservoirs changes …

Coal reservoirs especially deep unminable coal reservoirs, are viable geological target
formations for CO2 storage to mitigate greenhouse gas emissions. An advantage of this …

CO 2-enhanced coalbed methane (CO 2-ECBM) recovery has the triple benefits of
recovering clean resources, ensuring coal mine safety, and achieving CO 2 geological …

To study the swelling/shrinkage strain effects of different phases of CO 2 when injected into
anthracite and the influence that has on the dynamic evolution of coal permeability, an …

Injection of gas mixture (CO 2/N 2) into coal seam can both enhance methane recovery and
reduce carbon dioxide emission. Coal permeability determines the mass transport speed …

CO2–brine–rock interaction impacts the behavior and efficiency of CO2 geological storage;
a thorough understanding of these impacts is important. A lot of research in the past has …

The injection of CO 2 into deep coal seams can not only increase the recovery of CH 4 but
also contribute to the geological sequestration of CO 2. In deep coal seams, CO 2 can easily …

In recent times, enhanced deep-buried coalbed methane recovery has increased the
interest in coal and unconventional natural gas exploration. This study investigated liquid …

Enhanced coalbed methane (ECBM) core flooding experiments are a direct way to observe
the gas displacement process, the competitive adsorption and the effect of coal swelling and …

Seam gas pre-drainage, is widely used as an effective method to control gas and coal
outburst in underground coal mines. However, in CO 2 abundant low permeable seams, this …
