Do CO2 Injections Pose Risk of Harmful Earthquakes?
How common are measurable earthquakes in association with oilfield operations? The answer is: exceedingly rare. Nevertheless, another scientific paper has raised the possibility of seismic events occurring as a result of injection of CO2 to stimulate new oil production from depleted oil fields. Since this process, known as enhanced oil…

Seismicity and carbon storage: MIT responds to Zoback
In the December 2012 issue of the Proceedings of the National Academy of Sciences (PNAS), a published letter by MIT researchers Ruben Juanez, Howard Herzog and Brad Hagar provides several cogent geophysical counter-arguments to a 2012 PNAS Perspectives piece by Stanford researchers Mark Zoback and Steve Gorelick. The two had…

Seismic Risk Won’t Threaten the Viability of Geologic Carbon Storage
This week’s rumblings against carbon capture and storage (CCS) as a powerful means to mitigate global climate change come not from any natural geological source, but solely from an opinion piece published in this week’s Proceedings of the National Academy of Science (PNAS) Perspectives. Despite the arguments of two Stanford…
