The vast majority of Oklahoma’s recent earthquakes occurred in areas where the energy industry pumped underground massive amounts of waste fluid byproducts of oil and gas production, scientists write in a new paper published Thursday.

Plug-Back or Prove It: Oklahoma’s Anti-Earthquake Orders in Action

Oil-field workers use sledgehammers to unstick a pipe at the George saltwater disposal well near Wakita in northwestern Oklahoma.

Two burly ben armed with sledgehammers take turns bashing a khaki-colored steel flange fastened to a pipe in the middle of a soggy, gravely lot near Wakita in northwestern Oklahoma.

The tangle of valves and fittings, called the Christmas tree, has to come off before Jay Storm’s crew can start their work in earnest.

“Everything is a little seized up this morning, so we’re having to manually try to get a couple different components separated by hand,” says Storm, completions supervisor for Tulsa-based Eagle Energy Exploration.

As Oklahoma Agency Pointed to Natural Causes, Staff Suspected Quakes Were Linked to Oil

The Oklahoma Geological Survey on April 21 acknowledged Oklahoma’s ongoing earthquake surge is “very likely” triggered by wastewater disposal wells used by the oil and gas industry, a formal recognition that comes after years of scientific research that reached similar conclusions.

Oklahomans Feel Way More Earthquakes Than Californians; Now They Know Why

Austin Holland, research seismologist at the Oklahoma Geological Survey, gestures to a chart of Oklahoma earthquakes in June 2014 as he talks about recent earthquake activity at his offices at the University of Oklahoma in Norman, Okla. The state had three times as many earthquakes as California last year.

A magnitude-3.0 earthquake is small, but most people can feel it. Historically, Oklahoma got less than two of those a year, but in 2013 it became two a week.

It's only gotten more active since then — last year, the state had three times as many earthquakes as in the entire seismically active state of California.

PBS Newshour: Oklahoma Links Earthquakes To Oil And Gas Industry Wastewater

The Oklahoma Geological Survey said Tuesday it is "very likely" that most of the state's recent earthquakes were triggered by the subsurface injection of wastewater from oil and natural gas drilling operations.

StateImpact Oklahoma's Joe Wertz appeared on the PBS News Hour with Gwen Ifill tonight to talk about the connection.

Geologists Link Oklahoma Earthquakes To Fracking Waste Disposal

Originally published on Thu April 23, 2015 2:24 pm

The Oklahoma Geological Survey said Tuesday it is “very likely” that most of the state’s recent earthquakes were triggered by the subsurface injection of wastewater from oil and natural gas drilling operations.

Geologists have been studying the cause of hundreds of earthquakes that have shaken the homes and the nerves of residents in central and north-central Oklahoma, where the pace of oil and gas drilling has accelerated in recent years.

As earthquakes continue to surge in Oklahoma and seismologists warn of more frequent and more damaging shaking, the state’s oil and gas regulator is issuing new orders to companies operating wells in seismically active regions of the state.

The Oklahoma Corporation Commission’s new requirements, known as directives, were mailed March 18 to 92 people or companies operating 347 Arbuckle formation disposal wells in quake-prone regions of the state.
