... and can be used to detect leaks of volatile organic compounds (VOCs) from process equipment. Using OGI to detect leaks is more effective than using the US Environmental Protection Agency’s Method 21 because OGI is visual, making detection faster, and can survey an area instead of one component at a time...

... that of progressing cavity pumps (PCPs). In the period from 2008 to 2012, an annual average of 580 downhole failures occurred, 54% of which were caused by tubing leaks. In an effort to reduce these tubing failures, a pilot program was commenced to install rod guides in wells with the highest failure rate...

The public furor several years ago over whether fracturing polluted water supplies led to studies of how unconventional exploration and production (E&P) affects air quality. Some high-profile academic studies said methane leaking from gas operations are far higher than thought...
