Abstract
Summary
Moment tensor inversion of microseismicity can be used to image the strain tensor through space and time around the injection volume, resolve the associated dynamic stress variations, and determine the orientations of fractures in the discrete fracture network (length scales of these ruptures can be observed in the frequency content of the waveforms). All of these quantities are of direct import to geomechanical models and may be directly used to as inputs in terms of the stimulated DFN as well as establishing the dynamism of the stress and strain conditions to allow for better understanding of the fracturing process.
