"If they can increase the likelihood of getting a productive well every time they drill, it would be huge," says Lawrence Hutchings, a Berkeley Lab
microearthquake imaging specialist who has worked in geothermal fields worldwide.
Taking the 1[0.sup.4] J energy level of
microearthquake during the track roadway excavation in Panel 402103 as the study object, the relevant parameters can be approximately obtained (Table 3), based on the statistical results from in situ measurements and laboratory tests [28, 29].
