Hydraulic Fracturing and Seismicity in the Western Canada Sedimentary Basin

This study shows that the most recent cases of induced earthquakes in Western Canada are strongly correlated in space and time with ongoing hydraulic fracturing activities. These findings, the authors say, have far-reaching implications for assessment of induced-seismicity hazards. Key findings: The development of most unconventional oil and gas resources relies upon subsurface injection of …

Stress changes before and after the Wenchuan Earthquake using hydraulic fracturing measurements

This study draws conclusions from data gathered over a period of 10 years in the earthquake prone area of the Longmenshan fault belt, Sichuan, China. They used the method of in situ stress measurement by applying hydraulic fracturing and conducted measurement campaigns before and after the devastating quake in the Wenchuan Valley in 2008 in …

On Shaky Ground: Fracking, Acidizing, and Increased Earthquake Risk in California

This study evaluates links between wastewater injection and the 2011 Mw 5.7 earthquake sequence in California. Key findings: In light of the known environmental and health risks from drilling, well stimulation and wastewater disposal, the link between wastewater injection wells and earthquakes in other states, the potential for a massive expansion of drilling and wastewater …

Injection-Induced Earthquakes

Injection-Induced Earthquakes Author(s): William L. Ellsworth Date: 07.2013 Source / Publisher: Science Key findings: More than 300 earthquakes above a magnitude 3.0 occurred from 2010-2012, compared with national average rate of 21 earthquakes per year observed from 1967-2000. It coincides with the injection of wastewater in deep disposal wells. Abstract Fulltext See also: Laura Beans, …

Fluid Migration Mechanisms due to Faulty Well Design and/or Construction: An Overview and Recent Experiences in the Pennsylvania Marcellus Play

Fluid Migration Mechanisms due to Faulty Well Design and/or Construction: An Overview and Recent Experiences in the Pennsylvania Marcellus Play Author(s): Anthony Ingraffea Date: 01.2013 Key findings: Evidence linking water contamination to fracking-related activities has increased. The disposal of fracking wastewater has been causally linked to earthquakes. Air quality impacts from fracking-related activities are clearer …
