SMU Daily Campus: SMU seismologists investigate cause of North Texas earthquakes

SMU Heather DeShon earthquakes seismologyJournalist Jehadu Abshiro of the SMU Daily Campus covered the research of SMU seismologist Heather R. DeShon.

DeShon is leading the effort to trace the source of a recent sequence of small earthquakes in North Texas and any relationship they may have to the injection of waste water by energy companies using shale gas production to recover gas.

AGI’s Earth magazine covers SMU seismic research in Barnett Shale region

Thumbnail.jpgEarth magazine’s Carolyn Gramling interviewed SMU geophysicist Brian Stump about the operation of a saltwater injection disposal well that was a “plausible cause” for a series of small earthquakes in the Dallas-Fort Worth area in 2008.

The May 13 article in Earth, the magazine of The American Geological Institute, explores the research into the earthquakes, which occurred in an area of North Texas where the vast Barnett Shale geological formation traps natural gas deposits in subsurface rock.

SMU-UT study shows “plausible” connection between DFW quakes, saltwater injection well

Main.jpgA study of seismic activity near Dallas/Fort Worth International Airport by researchers from SMU and UT-Austin reveals that the operation of a saltwater injection disposal well in the area was a “plausible cause” for the series of small earthquakes that occurred in the area between October 30, 2008, and May 16, 2009.

The incidents under study occurred in an area of North Texas where the vast Barnett Shale geological formation traps natural gas deposits in subsurface rock.

Production in the Barnett Shale relies on the injection of pressurized water into the ground to crack open the gas-bearing rock, a process known as “hydraulic fracturing.” Some of the injected water is recovered with the produced gas in the form of waste fluids that require disposal.

News reports: SMU deploys seismic stations to study earthquakes

Rare earthquake activity in the Dallas-Fort Worth area has prompted the National Science Foundation to loan SMU 10 seismic stations to study the phenomenon. News reports about the research have been filed by The Wall Street Journal, WFAA-TV Channel 8, the Dallas Morning News and others.
