Ohio Utica Shale

State installing seismographs at Youngstown injection well

More December news:

The Youngtstownn Vindicator reported in early December that the Ohio Department of Natural Resources was installing new seismographs to detect earthquakes near a brine injection well in Youngsatown.

The equipment was installed by the Lamont-Doherty Earth Observatory at Columbia University.

The observatory had reported that a small earthquake on Nov. 25 was a few blocks from the D&L Energy Inc. injection well. It was the eighth small quake centered in Mahoning County.

Most of the quakes have been reported about 7,500 feet below the bottom of the D&L well on Youngstown's wst side.

The new equipment  _ four seismographs _ will enable scientists to better pinpoint the location of the earthquakes and to determine if the injection well is triggering the quakes.

It is an issue that has been raised in Arkansas, Colorado  and other states.

Injection wells are used in Ohio to dispose of brine and drilling wastes by injecting it under pressure into underground rock formations. Ohio has nearly 200 injection wells.
