Explaining long-range fluid pressure transients caused by oilfield wastewater disposal using the hydrogeologic principle of superposition

Injection-induced earthquakes are now a regular occurrence across the midcontinent United States. This phenomenon is primarily caused by oilfield wastewater disposal into deep geologic formations, which induces fluid pressure transients that decrease effective stress and trigger earthquakes on critically stressed faults. It is now generally accepted that the cumulative effects of multiple injection wells may result in fluid pressure transients...
