2003 analyzed the relationship between the anisotropy of the variation of dynamic rock resistivity and the change of water network conductive path caused by the extension of rock fracture through laboratory experiments, and then proposed a quantitative method of identifying the extending premonition of hidden fracture; the variation of the resistivity of water-saturated rock
under uniaxial compression was studied (Brace, 1975), and the results showed that under 1/3 to 2/3 of the burst pressure during the loading process, the resistivity of saturated rock
initially increased and then decreased rapidly.
For example, the fracture surfaces of the natural argillaceous siltstone are smoother and the shape of the fragment is more irregular than the saturated rock.

The test results in our studies reveal that the cohesion and internal friction angle of the natural Zigong argillaceous siltstone are larger than those of the corresponding saturated rocks (Table 2).
Water can influence significantly the compressive strength and deformability of rocks, even though the water contents of rocks are not high for the natural and saturated rocks.
Now scientists have for the first time been able to carry out a continent-wide analysis of the water that is hidden under the surface in aquifers (a body of saturated rock
through which water can easily move).
Drake could never have imagined wells drilled at steep angles to reach a small oil or gas deposit several miles from the surface location of the drill rig, or drilled horizontally to drain thin, flat layers of oil saturated rock
It has been blessed with the largest water component of the aquifer and, despite significant drawdown in years past, in some places it still has more than 1,000 feet of saturated rock
They live quite happily in salt lakes, saturated rock
salt solutions, the bitter cold and the intense heat of the desert.
While comparing dry and saturated rock
material, strength identification can be done directly according to UCS or deformability values.
Comparison of velocity, density, Acoustic Impedance and Reflection Coefficient estimated from seismic and well log data shows that area is less complex (as compared to collisional belt resulting in folding and faulting) with horizontal reflectors furthermore density and velocity values of Lower Goru Formation indicate saturated rocks
