Short summary
Faint earth tremors may occur when exploiting geological reservoirs to extract hydrocarbons, produce geothermal energy, or store CO2. This microseismicity may reveal the location of fractures within the reservoir, and the mechanical stresses acting on them. We present and demonstrate (on laboratory data) a new workflow for analysing microseismic data, considering fracture models relevant to geoengineering applications to infer fracture mechanisms and the stress conditions local to them.
