Gas Drilling, North Dakota

Some cool earth image images:

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 oil production is booming.

Companies hoping to extract oil from the Bakken formation have drilled hundreds of new wells in the last few years; natural gas often bubbles up to the surface as part of the process. Lacking the infrastructure to pipe the gas away, many drillers simply burn it in a practice known as flaring.

On November 12, 2012, the Visible Infrared Imaging Radiometer Suite (VIIRS) on the Suomi NPP satellite captured this nighttime view of widespread gas flaring throughout the area. Many of the specks of light are evidence of gas flaring, though others may be the lights around drilling equipment. 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 filtering techniques to observe 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, meaning it 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 gas pipeline and processing facilities in the region, about 29 percent of that gas is flared.

tom coates, jane mcgonigal, cal henderson, chris heathcote and others scramble to take eighty-some-odd squares of paper and "draw" a little space invader's action appropriate for the 2" resolution google earth imaging that took place at noon on saturday, exactly. a little red airplane flew laps over the o'reilly campus, initiating all kinds of weird oversized drawings, street chalking, and mostly lots of people laying down flat on the ground, on cue, hoping to be captured on Google Earth..supposedly this'll show up in Google Earth in a month or so..
