Based on the proposed calculation method for determining different dip angle fracture permeability coefficients derived from well flow vibration equation and self-developed slug test system, research in a field fractured rock mass was carried out based underground water sealed cavern project of National Huangdao Petroleum Reserve. The formation lithology site granite gneiss, fractures were not ...

The Industrial Revolution has led to a substantial i ncrease in the generation and release of greenhouse gases (GHG) into environment. These GHGs like CO2 if present in abundance in the atmosphere cause damage to the natural ecosystems through global warming. One of the possible approaches to mitigate the global warming phenomena is by safely and long-term underground disposal of CO2 in suitabl...

Seismic tomography revealed a low seismic velocity (-5%) and high Poisson's ratio (+6%) anomaly covering about 300 square kilometers at the hypocenter of the 17 January 1995, magnitude 7.2, Kobe earthquake in Japan. This anomaly may be due to an overpressurized, fluid-filled, fractured rock matrix that contributed to the initiation of the Kobe earthquake.

[1] One potential consequence of global climate change and rapid changes in land use is an increased risk of flooding. Proper understanding of floodwater infiltration thus becomes a crucial component of our preparedness to meet the environmental challenges of projected climate change. In this paper, we present the results of a long-term infiltration experiment performed on fractured ash flow tu...

An experimental system we developed combines triaxial rock deformation and mass spectrometry to measure noble gas flow before, during, and after rock fracture. Gas flow through a granite and basalt in its unfractured condition allows estimation of “native” permeability. Geogenic noble gas is released during triaxial deformation (real time) and is related to volume strain and acoustic emissions....
