Standout findings in a new major field study on methane emissions from natural gas collection and processing facilities across 13 states, led by Colorado State University include a couple of points:
First, of 130 facilities that collect natural gas from production wells, remove impurities and deliver it to inter- and intrastate pipeline networks, 101 had methane loss rates below 1 percent – including 85 of the 114 gathering facilities and all 16 of the processing plants studied. Put another way, methane containment at these facilities is more than 99 percent.
Second, the majority of emissions resulted from abnormalities involving broken or faulty equipment – issues that are relatively easy to address.

Pittsburgh Post-Gazette: The new year has seen crude oil prices continue to stumble and U.S. oil production continue to soar, and those trends are not likely to subside — at least in the short term.
Total U.S. crude oil production reached 9.1 million barrels per day (bbl/d) during the week ending Jan. 9, an increase over last year’s total of 8.1 million, according to the U.S. Energy Information Administration.
And that figure is expected to grow. The agency forecasts total crude production will average 9.3 million barrels per day in 2015 and climb to 9.5 million in 2016, “which would be the second-highest annual average level of production in U.S. history; the highest was 9.6 million bbl/d in 1970,” the EIA said in its short-term energy outlook released last week.

As we look at the Obama administration’s plan to impose new regulations on methane emissions from oil and natural gas operations, some important points.
First, when it comes to methane emissions, the White House is focusing on a relatively small piece of the big picture. Data from EPA’s Greenhouse Gas Reporting Program shows that methane emissions from natural gas and petroleum systems (161.6 million metric tons of carbon dioxide equivalent) represent just 28.5 percent of total methane emissions (567.3 million metric tons CO2 equivalent). That’s a fairly small wedge in the overall pie.

So long, 2014. From an energy standpoint, you’ll be missed. Let’s count the ways:
Surging domestic oil and natural gas production – largely thanks to safe hydraulic fracturing and horizontal drilling – is driving an American energy revolution that’s creating jobs here at home and greater security for the United States in the world.
It’s a revolution with macro-economic and geopolitical impacts, for sure. But it’s also a revolution that’s benefit virtually every American.

New research by the University of Texas shows what other studies have shown: methane emissions from natural gas production are lower than previously estimated. The UT study found that emissions represent just 0.38 percent of production – about 10 percent lower than a 2013 study by the same research team.
The UT study checked two sources of methane emissions in natural gas production: processes to clear wells of accumulated liquids to increase production, called liquid unloadings; and pneumatic controller devices that open and close valves.
The study found that just 19 percent of pneumatic devices accounted for 95 percent of emissions from that equipment, and that just 20 percent of wells with unloading emissions that vent to the atmosphere accounted for 65 percent to 85 percent of those emissions. David Allen, the study’s principal investigator:
“To put this in perspective, over the past several decades, 10 percent of the cars on the road have been responsible for the majority of automotive exhaust pollution. Similarly, a small group of sources within these two categories are responsible for the vast majority of pneumatic and unloading emissions at natural gas production sites.”
The results suggest that technologies and practices already in use by industry – voluntary efforts and those to comply with federal green completions rules that become standard in January – are working to reduce methane leaks.

The Hill: Methane leaks from natural gas drilling and production have fallen from the last estimate more than a year ago, according to a study sponsored by the industry and an environmental group.
Leaks of methane, the main component of natural gas, now represent 0.38 percent of production volumes, according to the study released Tuesday.
That is 10 percent lower than what the same University of Texas research team found in September 2013. Methane is a greenhouse has about 20 times more potent than carbon dioxide.
“Study after study shows that industry-led efforts to reduce emissions through investments in new technologies and equipment are paying off,” Howard Feldman, director of regulatory and scientific affairs at the American Petroleum Institute, said in a statement.
“This latest study shows that methane emissions are a fraction of estimates from just a few years ago,” he said.

New Orleans Times-Picayune: After more than a decade of work and a $7.5 billion investment, Chevron has started oil and gas production at its Jack and St. Malo fields in the deepwater Gulf of Mexico. The fields are among the largest in the region, expected to produce more than 500 million barrels of oil equivalent over the next three decades.
The Jack and St. Malo fields, discovered in 2003 and 2004 respectively, are located 25 miles apart in the Walker Ridge region of the Gulf about 280 miles south of New Orleans.
Oil and gas from the fields will flow back to a single, floating production platform located between the two fields. The platform has the capacity to produce up to 170,000 barrels of oil and 42 million cubic feet of natural gas per day.

The New York Times has an editorial urging Washington to regulate emissions of methane – no surprise as “The Gray Lady” has to uphold her “green” bonafides. But methane as an “overlooked” greenhouse gas, as the editorial’s headline states? Hardly.
While the Times may have just discovered methane, industry has been working to reduce emissions – and is succeeding, at a rate that casts doubt on the need for a new federal regulatory layer.
