Study on experiment conditions of marine shale gas seepage law

Journal of Natural Gas Geoscience, 2016
In order to discover the conditions suitable for testing shale gas seepage law, marine shale gas cores were taken from southern China. Samples were tested by using the differential pressure-flow rate method with actual gas under two modes (e.g.

Permeability evolution during progressive development of deformation bands in porous sandstones [PDF]

, 2003
Triaxial deformation experiments were carried out on large (0.1 m) diameter cores of a porous sandstone in order to investigate the evolution of bulk sample permeability as a function of axial strain and effective confining pressure. The log permeability

Confining Pressure Forecasting of Shield Tunnel Lining Based on GRU Model and RNN Model. [PDF]

Sensors (Basel)
The confining pressure has a great effect on the internal force of the tunnel. During construction, the confining pressure which has a crucial impact on tunnel construction changes due to the variation of groundwater level and applied load.
