Gas Injection Probably Triggered Small Earthquakes Near Snyder, Texas

AUSTIN, Texas — A new study correlates a series of small earthquakes near Snyder, Texas between 2006 and 2011 with the underground injection of large volumes of gas, primarily carbon dioxide (CO₂) — a finding that is relevant to the process of capturing and storing CO₂ underground.

Although the study suggests that underground injection of gas triggered the Snyder earthquakes, it also points out that similar rates of injections have not triggered comparable quakes in other fields, bolstering the idea that underground gas injection does not cause significant seismic events in many geologic settings.

AUSTIN, Texas — A report from the Massachusetts Institute of Technology (MIT) and The University of Texas at Austin urges the U.S. to accelerate efforts to pursue carbon capture and storage (CCS) in combination with enhanced oil recovery (EOR), a practice that could increase domestic oil production while significantly curbing emissions of carbon dioxide (CO₂).

For decades the oil industry has used CO₂ to extract oil from mature fields, often relying on purchased CO₂ from natural sources. The idea of seeking CO₂ from industrial sources, such as coal- and natural gas-fired electricity plants, has gained currency because of public concerns about carbon dioxide emissions. (more…)
