NASA-NOA Satellite Sees Gas Drilling, North Dakota at Night (image) NASA/Goddard Space Flight Center Share Print E-Mail Caption Northwestern North Dakota is one of the least-densely populated parts of the United States. Cities and people are scarce, but satellite imagery shows the area has been aglow at night in recent years. The reason: the area is home to the Bakken shale formation, a site where gas and oil production are booming. On Nov. 12, 2012, the Visible Infrared Imaging Radiometer Suite (VIIRS) on the Suomi NPP satellite captured this nighttime view of widespread drilling throughout the area. Most of the bright specks are lights associated with drilling equipment and temporary housing near drilling sites, though a few are evidence of gas flaring. Some of the brighter areas correspond to towns and cities including Williston, Minot, and Dickinson. The image was captured by the VIIRS "day-night band," which detects light in a range of wavelengths from green to near-infrared and uses "smart" light sensors to observe dim signals such as gas flares, auroras, wildfires, city lights, and reflected moonlight. When VIIRS acquired the image, the Moon was in its waning crescent phase, so the landscape was reflecting only a small amount of light. According to the U.S. Energy Information Administration, natural gas production from the Bakken shale has increased more than 20-fold between 2007 and 2010. Gas production averaged over 485 million cubic feet per day in September 2011, compared to the 2005 average of about 160 million cubic feet per day. Due to the lack of a gas pipeline and processing facilities in the region, about 29 percent of that gas is flared.
