Leakiness («leak rate») is defined as the amount of methane a company emits per unit of oil and gas it produces at all the oil and gas fields it operates in the United States.

Storing gas underneath the ocean floor is a «poor choice,» he said, since gas leaking at the same rate could spur acidification and harm corals and other sea life.

He then examined how the world's temperatures would fare if that amount of gas leaked at rates of 1 percent every 10, 100, and 1,000 years.

A new study provides one of the first quantitative estimates of the methane leak rate from the blowout of a natural gas well in California in 2015, suggesting that emissions from this event temporarily doubled those from all other sources in the entire Los Angeles Basin, including landfills, dairies, and other leaks.

Their report emphasizes the utility of rapid - response airborne chemical sampling in providing leak rate data, and it reveals how single vulnerabilities in the natural gas infrastructure can impact local and federal climate policies.

New research to re-examine distribution system leak rates has been funded by the Environmental Defense Fund as part of a larger project to quantify lost methane from the natural gas system.

Though focused on end uses of natural gas, the paper also shows how results are affected by highly uncertain leak rates from natural gas production and delivery.

«A relatively fast frame rate on your camera provides more information about where the gas is leaking from than having very high - resolution images.»

In the paper, the researchers showed that their system could image methane gas leaking from a tube about 1 meter from the camera with a video - rate imaging speed of approximately 25 frames per second.

From his ethane research and other international studies, he learned that there appears to be a much higher ethane source in the earth's Northern Hemisphere than in the Southern and a higher leak rate in the central United States than in more eastern oil and gas fields, and that some oil and gas fields in the central United States leak at much higher rates than others.

That means the U.S. is likely leaking 2.25 percent, not 1.5 percent, of all the natural gas used, according to the new study, which helps explain why concentrations measured in the atmosphere keep rising above expected rates.

A University of Texas study found last year that natural gas wells leak methane at about the rate reported in U.S. Environmental Protection Agency methane emission inventories, and the leaks can be contained with emissions control technology.

Many wells have systems designed to capture those emissions or flare them, but oil and gas equipment and their leak rates vary from region to region, he said.

Brain research raises the possibility of a very exotic future (this article assumes that such animals wouldn't be vicious or use their new - found smarts to drive other species to extinction) «Liberated» mice from Italian lab now housed in poor conditions Methane leaks of shale gas may undermine its climate benefits: If methane leak rates are more than 3 percent of output, fracking of shale gas formations may be boosting greenhouse gas emissions rather than lowering them.

The methane leak rates found in Pennsylvania were similar to those found in the atmosphere near natural gas fields in Utah's Uintah Basin and Colorado's Denver - Julesberg Basin, showing that methane leaks are widespread in natural gas fields across the country, the study says.

The leaking well's owner, Southern California Gas Co., warned state utility regulators in 2014 of «major failures» without a rate hike to pay for comprehensive inspections of 229 storage wells.

Then U.S. shale gas production could account for about 12 percent of the global methane increase over that time (it scales at approximately 4 percent of global increase per 1 percent leak rate).

Experts agree that methane leaked or vented from natural gas operations is a real concern, yet estimated emission rates vary greatly 3/4 from 1 to 8 percent of total production.

The data presented by Miller et al. constrains the overall leak rate from the oil and gas supply chains — providing an independently derived aggregate estimate of fossil fuel sources of methane emissions.

Let's assume a 3 percent leak rate during shale gas production.

The actual leak rate is poorly known, but in any reasonable case U.S. shale gas production is a small, but not trivial, contributor to the global methane increase over the last several years.

The rate at which methane leaks into the atmosphere from natural gas production «is a critical question that we must answer,» say Reps. Henry Waxman and Bobby Rush, who have called on the chair of the House Energy and Commerce Committee... Continue reading →

Dr. Stanton's analysis identifies a range of possible emission rates associated with the project, taking into account uncertainty regarding methane leak rates and the lifecycle contribution of natural gas to greenhouse gas concentrations in the atmosphere.

A string of studies by the National Oceanic and Atmospheric Administration show that the core ingredient in natural gas, methane, is leaking at rates far higher than previously suspected.

To put that number in context, a recent peer - reviewed study found that methane leaks from Texas» Barnett Shale, a field that produces 7 percent of the nation's natural gas, had an average leak rate of 65 tons per hour.

-LSB-...] But he said the leak rate would fall sharply over time once the natural gas in the reservoir is exhausted.

EPA estimates that natural gas systems leaked about 1.2 percent of the methane that passed through them in 2012, but many recent studies suggest the rate may be much greater, perhaps 3 to 10 percent.

Though the rate of leak is such that it's not a huge climate risk, remember than methane is far more potent greenhouse gas than carbon dioxide, though it is much shorter lived in the atmosphere.

Hence in this latter comparison, which primarily compares the effect of the CO2 and CH4 emitted by these two sectors (and hence the leak rate threshold decreases with a nearer - term perspective), even very small leak rates would make the mean natural gas plant as environmentally damaging as coal.

In comparison with the aforementioned coal plant at the 5th percentile of current air quality emissions, the leak rate for the natural gas sector has to be only 1.9 %, 1.6 % or 1.1 % for 1.4, 3 and 5 % discounting, respectively, to match the damages from coal.
