A 3D-view of the microseismicity generated during reservoir stimulation reveals an unusual spatial distribution. The borehole, black squares, follows the usual geometry. The  lateral dips gently down from its toe (far westernmost tip) having been drilled on-azimuth parallel to the presumed minimum horizontal stress direction. The cloud of 38,383 microseismic events detected by a well-distributed […]

Micro earthquakes produced by high pressure fracking at Preston New Road do not follow the expected distributional pattern. At first sight all looks to be business like. Cuadrilla’s hydro-fracking, at the end of 2018, generated a tight swarm of over 38,000 micro earthquakes at depths below 2km. Furthermore, the energy released neatly followed the anticipated […]
