The hydraulic criterion of the rematch is when the pressure given by two successive hydraulic tests is constant.
Nineteen hydraulic tests have been conducted in two, 500 m deep, vertical boreholes.
Permeable intervals identified from the hydraulic tests were mostly located above the cavern roof.
The mechanical and hydraulic tests are performed to characterize the pervious concrete.
A drill-core was taken in this zone and hydraulic tests were performed.
At each shear step, we performed 5 8 high precise hydraulic tests with different hydraulic gradient.
To determine flow parameters, the tracer tests were complemented by a comprehensive set of depth-specific borehole and hydraulic tests.
Under hydraulic tests, these hollow fiber membrane supports possess high burst pressures from 13 to 24 bar.
The most effective, reliable and standard way of determining these characteristics is to conduct and analyze hydraulic tests such as pumping test.
Field studies and hydraulic tests found values of σ from 0.1 to 0.3, 0.23, and 0.47 (Snow 1970; Dverstorp and Andersson 1989; Tsang et al. 1996).
1980 to 1986: EGS Bad Urach - deepening of the borehole to 3,488 m at 147°C and hydraulic tests for single borehole system.
