A comprehensive review of the environmental consequences of unconventional energy extraction and hydraulic fracturing, including production estimates, water intensity, issues of well integrity and potential leakage of chemicals, brines, or gases, water quality, the potential for induced seismicity and the life-cycle emissions of hydrocarbons.
Enhanced Remote Earthquake Triggering at Fluid-Injection Sites in the Midwestern United States
van der Elst NJ, HM Savage KM Keranen, GA Abers
This study demonstrates the link between large remote seismic waves and the increased susceptibility of earthquakes triggered localy around injection areas.
This paper reviews recent seismic activity potentially associated with oil and gas activity and particularly, assesses the scientific understanding of induced earthquakes, and discusses the key scientific challenges in assessing this hazard."
Potentially induced earthquakes in Oklahoma, USA: Links between wastewater injection and the 2011 Mw 5.7 earthquake sequence
Keranen KM, Savage HM, Abers GA, Cochran ES
Significant earthquakes are increasingly occurring within the continental interior of the United States, including five of moment magnitude (Mw) 5.0 in 2011 alone. Concurrently, the volume of fluid injected into the subsurface related to the production of unconventional resources continues to rise. Here we identify the largest earthquake potentially related to injection, an Mw 5.7 earthquake in November 2011 in Oklahoma.
Induced Seismicity Potential in Energy Technologies

In the past several years, some energy technologies that inject or extract fluid from the Earth, such as oil and gas development and geothermal energy development, have been found or suspected to cause seismic events, drawing heightened public attention. Although only a very small fraction of injection and extraction activities among the hundreds of thousands of energy development sites in the United States have induced seismicity at levels noticeable to the public, understanding the potential for inducing felt seismic events and for limiting their occurrence and impacts is desirable for state and federal agencies, industry, and the public at large. To better understand, limit, and respond to induced seismic events, work is needed to build robust prediction models, to assess potential hazards, and to help relevant agencies coordinate to address them.
