Another Heat Map find. Then did some research. The Backken oil filed is ON FIRE ! Literally. Go Google Night Time Satellite images of the Bakken oil field in the US. The amount of light given off by flaring gas ( no way to transport it out of this area) is as great as the light from the city of Chicago. So yeah, I figured if they are putting out that much flared gas - they really are making money. Note to self: Need to get live satellite imagery.
