METHOD FOR CALCULATING SPATIAL AND TEMPORAL DISTRIBUTION OF THE GUTENBERG-RICHTER PARAMETER FOR INDUCED SUBSURFACE SEISMIC EVENTS AND ITS APPLICATION TO EVALUATION OF SUBSURFACE FORMATIONS
METHOD FOR CALCULATING SPATIAL AND TEMPORAL DISTRIBUTION OF THE GUTENBERG-RICHTER PARAMETER FOR INDUCED SUBSURFACE SEISMIC EVENTS AND ITS APPLICATION TO EVALUATION OF SUBSURFACE FORMATIONS
A method for evaluating fractures induced in subsurface formations includes determining hypocenters and origin times of induced seismic events from seismic signals detected by seismic sensors deployed above a volume of the subsurface formations to be evaluated and recording the detected signals for a selected time. A modified Gutenberg-Richter exponent is determined for each induced seismic event having at least a selected number of other induced seismic events within a selected radial distance thereof. A spatial distribution of the modified Gutenberg-Richter exponents is used to determine at least one property of the induced fractures.
