Ohio Utica Shale

Update on Youngstown quakes

By Bob Downing Published: January 3, 2012

The Ohio Department of Natural Resources acted appropriately in shutting down an injection well in Mahoning County that has been linked to earthquakes, said Terry Fleming of the Ohio Petroleum Council.

Fleming issued his statement today.

He said the state agency acted with "appropriate due caution" in shutting down the Northstar Disposal Services LLC well west of downtown Youngstown in Youngstown Township.

Situations like those encountered in Youngstown are "very rare," he said.

The state and the company on Friday agreed to temporarily shut down the well to allow for more investigation.

On Saturday, a 4.0-magnitude earthquake struck near the injection well where briny waste from drilling gets pumped underground for permanent disposal.

The pressure inside the well may have been high enough to trigger the quake, even though operation was being shut down, state officials said.

State Sen. Bob Hagan, D-Youngstown, called for a moratorium on injection wells and asked the U.S. Environmental Protection Agency to investigate.

Ohio has a total of 177 injection wells to dispose of drilling wastes from Ohio drillers and those in other states.

Fleming defended the injection wells and said Ohio needs those wells for disposal as the Utica shale boom begins.

Ohio should make its decisions based on sound science, not politics, he said.

It was the 11th quake and the largest in Mahoning County since last March, when the quakes started.

A Dec. 24 quake was a 2.4-magnitude.

All of the quakes occurred within two miles of the injection well.

The state and the company agreed to the closure, even though the state cannot prove that the injection well caused the quakes.

The well goes to a depth of 9,100 feet and began operations in late 2010. The liquid waste is kept under pressure of 2,500 pounds per square inch, according to state records.

The new testing at the Youngstown Township well is expected to get under way this week.

Company officials plan to plug about 1,100 feet of open space at the bottom of the well.
