The researchers used data from the borehole seismometers to calculate the underlying rock's Poisson's ratio. This ratio measures the 3D elastic properties of rocks: think about a sponge, Huang says.
Borehole pump and slug testing are conducted to determine aquifer hydraulic properties, for example hydraulic conductivity and transmissivity, and test well performance. In Borehole pump tests, water ...
The region the researchers examined is covered by a network of borehole seismometer stations located about every 25 kilometers. Because the seismometers are placed about 100 meters deep in ...
