As one of the most significant clean energy sources, the migration characteristics and
extraction processes of coalbed methane (CBM) have been extensively studied. The …

In geological engineering, a series of safety problems caused by expansive mudstone are
common, such as slope instability and roadbed up-arch. In this paper, the mineral …

The complex rock fracture structures in reservoirs play an important role during methane
extraction. However, there is still a challenge to elucidate the impacts of adsorption …

Taking saturated, weakly cemented sandstone as the research object, nuclear magnetic
resonance (NMR) tests were performed before and after six freeze–thaw cycles without …

The key to shale gas exploration is the characterization of gas migration under the
combination of multiple factors. To address the long-standing energy challenge of rapidly …

Horizontal drilling is the major method of shale gas extraction, and hydraulic fracturing
