VOCs = Volatile Organic Compounds are a cause of SMOG. That might explain why there is so much smog in this VIDEO that was taken within 5 miles of Greenwood, TX, population 76.
The report gives information about flaring (VIDEO), which I know is of intense interest to people in Lewisville right now. (Don’t let them flare up your behind.)
Well Testing : flow testing conducted to determine the deliverability of a well.
(Sometimes the test may be conducted into a flow or gathering line; however, more often the liquids are produced into temporary tankage brought on site for the test, and the gas phase is either vented or flared.)
