Figure 10From: Mechanical origin of b-value changes during stimulation of deep geothermal reservoirs Velocity map soft systems. L=128, left: Map of log10[ V(x,y)] for a soft system. The average velocity is 〈V〉=0.000187. Right: The corresponding C=2 cluster-map. We identify the velocity cluster by setting all elements above C·〈V〉 to one (yellow) and below to zero (black).Back to article page
