Sentences with phrase «pneumatic controllers»

Here's what leakage from pneumatic controllers on a well looks like, thanks to infrared video posted by the Clean Air Task Force (tripod next time, guys?)

A team of researchers from the Cockrell School of Engineering at The University of Texas at Austin and environmental testing firm URS reports that a small subset of natural gas wells are responsible for the majority of methane emissions from two major sources — liquid unloadings and pneumatic controller equipment — at natural gas production sites.

A 2011 Western Regional Air Partnership analysis of oil and gas air emissions control requirements set by both states and the EPA said that gas - powered pneumatic controllers on oil and gas production equipment release VOCs and methane with every valve movement, and some release gas continuously.

The protocol provides the quantification requirements to generate carbon offset credits by retrofitting existing high - bleed pneumatic controllers with low - bleed options, thus reducing vented emissions of methane, a potent greenhouse gas.

The researchers sampled all identifiable pneumatic controller devices at each well site, a more comprehensive approach than the random sampling previously conducted.

«Our goal here was to measure a more diverse population of wells to characterize the features of high - emitting pneumatic controllers.»

Such wells often use pneumatic controllers, which siphon off pressurized natural gas from the well and use it to operate production - related equipment.

With last week's launch of The Environmental Partnership, let's take a more detailed look at the three emissions - reducing programs more than two dozen participating companies have announced as their initial focus: pneumatic controller upgrades, leak detection and well liquids removal.

His team's work suggests that emissions from pneumatic controllers and other equipment at production wells is between 57 - 67 % higher than the current EPA estimate.

The UT Austin - led field study closely examined two major sources of methane emissions — liquid unloadings and pneumatic controller equipment — at well pad sites across the United States.

According to the U.S. Environmental Protection Agency, high - bleed pneumatic controllers are among the largest sources of vented methane by equipment type in the U.S. oil & natural gas industry.

The average methane emissions per pneumatic controller reported in this study are 17 percent higher than the average emissions per pneumatic controller in the 2012 EPA greenhouse gas national emission inventory (released in 2014), but the average from the study is dominated by a small subpopulation of the controllers.

The EPA estimated in 2011 that natural gas drilling accounts for about 1,200 gigagrams, or 2.6 billion pounds, of methane emissions each year from well completions, equipment leaks and pneumatic controllers.

The UT Austin - led field study closely examined two major sources of methane emissions — liquid unloadings and pneumatic controller equipment — at well pad sites across the United States.

Click here for a presentation on the pneumatic controllers and here's a presentation on the plungers and processes that are used to extract liquids that can reduce the gas flow in older wells.

These would require facilities to limit venting, address emissions from pneumatic controllers and pumps, implement programs for leak detection and repair, conserve or flare gas in well completion, and repair compressors with high emissions.

Some of the emission reduction technologies implemented by industry include installation of vapor recovery units and various types of automated lift systems to control well venting, development of techniques for reduced emission completions, increased use of electric / solar driven pumps and low - bleed pneumatic controllers.

With my comprehension and exposure to testing and calibrating machinery such as pressure and temperature transmitters, valve positioners, and electronic and pneumatic controllers, I am positive that your organization will definitely be at the winning end.
