Significantly more methane is spewing into the atmosphere from natural gas wells and other drilling operations in North Texas’ Barnett Shale fields than previously estimated, according to a new series of studies, raising new questions about the relative benefits of drilling for more gas instead of burning coal.
The leaks came largely from operator mistakes, poor maintenance, or simple wear and tear on equipment – conditions that experts call preventable.
“A lot of it is human error. Somebody will leave a hatch open, and nobody goes back to the facility for more than a month, so it’s leaking this huge amount of methane out of the top,” said Robert Talbot, a University of Houston professor of atmospheric chemistry who was part of the research. “We’re hoping now that most of the companies will take a look at what they’re doing, and go ahead and do good maintenance.”
Leaks at the sites ranged from 0.01 percent to 47.8 percent of natural gas produced, with the vast majority on the lower end. Compressor stations and processing plants were found leaking at particularly high rates — far above EPA estimates. The region’s 275 compressor stations — which help process and transport gas — accounted for 40 percent of total oil and gas emissions.
“The industry is going to be continuing to do what it has been doing because that is already delivering progress,” he said. “Let’s not try to fix something that isn’t broken.”

Too late. We are selling our wheat farm. It has become too hard to make a profit and now with the change in rain patterns, too much. We have cashed out everything. The damage is done and now the fight for resources will begin.

I'm sure the gas is still quite trace amounts in the atmosphere. Lots of space up there above our heads. It's also a good thing we're so adaptable. D/FW area, if it jumped much (if any at all) I'm sure we're all adapting just fine. It's all about rate of change vs rate in ability to compensate. So far, no issues.

Dude, you are clueless, full of assumptions, and entirely missing the point, over and over again. I can't help someone who can't relate. My guess? You're another factoid, void of intuition and big-picture thinking.
Why should I bother to explain myself, when you can't even make simple connections?
The other suspect is an exploratory natural gas well that was being drilled just 150 meters from where the mud came bubbling up. The idea there is that it could have punctured the seal on a pressurized reservoir of water, releasing the angry half of a mud recipe.

The EPA ADMIT that they were paid off to stop their last investigation of fracking wells just before they were going to start looking at the effect on groundwater.
So the fracking industry are trying to claim that they are SAFE.
However, by the industry's own admission, a failure rate of 95 % is "acceptable".
Only 5 out of every 100 wells has held, without leaking.
