Many chemicals used in Texas fracking remain a mystery

on
For the past five years, biochemist Zac Hildenbrand has investigated potential links between unconventional drilling and water quality, collecting thousands of samples throughout the major shale plays in Texas.
Texas will deploy additional sensors to study a rash of earthquakes shaking the state as researchers try to determine whether the tremors are linked to the underground disposal of oilfield waste.

First research links California quakes to oil operations

on
In Kern County, the shaking topped out on Sept. 22, 2005, with three quakes, the biggest magnitude 4.6, researchers said.

The first experimental use of hydraulic fracturing was in 1947, and more than 1 million U.S. oil and oil wells have been fracked since, according to the American Petroleum Institute. The National Petroleum Council estimates that up to 80 percent of natural oil wells drilled in the next decade will require hydraulic fracturing. (AP Photo/Brennan Linsley)

Flotek releases report refuting criticism that it manipulated data

on
The Houston-based oil field services company launched an investigation of its chemicals and data analysis software after an Australian fund manager in November disputed the accuracy of Flotek’s self-reported results.

More quakes rattle Oklahoma, but state avoids tough measures

on
The quakes, which have been mostly small to medium sized, have caused limited damage, and no one foresees anything like the massive damage and deaths in the famous quakes in California, seismologists say.
In this June 26, 2014 file photo, Austin Holland, research seismologist at the Oklahoma Geological Survey, hangs up a chart depicting earthquake activity at their offices at the University of Oklahoma in Norman, Okla. A study published Thursday, July 3, 2014 by the journal Science explains how just four wells forcing massive amounts of drilling wastewater into the ground are probably causing quakes in Oklahoma. The wells seem to have triggered more than 100 small-to-medium earthquakes in the past five years, according to a study (AP Photo/Sue Ogrocki, File)

Oklahoma regulators order reduced injection well volumes after quakes

on
The Oklahoma Geological Survey has said it is “very likely” that most earthquakes are triggered by the subsurface injection of wastewater from the drilling operations.

Hundreds more earthquakes jolt Oklahoma in 2015

on
Quakes have been on the rise in Oklahoma following a boom in oil and gas activity — state officials have blamed the seismic activity on an increase in wastewater injections in drilling areas.
