Reservoir Deformation Estimation

A computing system, comprising:

• one or more electronic processors;
• and
• a memory system comprising one or more computer-readable media storing instructions thereon that, when executed by the one or more processors, are configured to cause the computing system to perform operations for characterizing a subterranean geologic formation's response to hydraulic fracturing, the operations comprising:
• acquiring data representing a plurality of seismic events caused by hydraulic fracturing of the subterranean geologic formation;
• determining, by at least one electronic processor, a plurality of seismic event moment magnitudes for respective seismic events in the plurality of seismic events;
• estimating, by at least one electronic processor, a first parameter representing a negative slope of a line relating seismic event frequency to seismic event magnitude for at least some of the plurality of seismic events;
• estimating, by at least one electronic processor, a second parameter representing an axis intercept of the line;
• and
• characterizing the subterranean geologic formation based at least in part on the first parameter and the second parameter.
