In situ stressHigh-rank coalCoalbed methanePermeabilityGas and water productionQinshui basinChina produced 17.1 billion cubic meters (BCM) of methane sourced from coal seams in 2015, of which 4.43 BCM is from wells drilled from the surface. This level of production is a clear indicator that ...
In-situ stressCoalbed methaneDepletionReservoir stabilityQinshui BasinThe in-situ stress and its behavior during depletion are critical for investigation of the reservoir permeability, wellbore stability, enhanced oil recovery (e.g. stimulation), fault reactivation, and reservoir management. However, the ...
The giant Changba-Lijiagou (Ch-L) Pb-Zn deposit is in the northeast part of the Xicheng ore cluster, Western Qinling Orogen. The ore genesis remains controversial; it could be either a sedimentary exhalative genetic type or an epigenetic hydrothermal genetic type. Here, in situ titanite U-Pb...
