This map of Montrail County, North Dakota covers some of the largest fields on the Nesson Anticline. The first time I showed the map, none of the outlines were there.
A geophysicist said he just interpreted the Red Sky 3-D seismic survey and there is a large fault at the east end of the survey he thought he saw. I went home and found
the boundaries of the Red Sky 3-D survey, overlaid the survey extent, and sent it to him. He responded it fit his interpretation, and asked if I noticed how the Parshall,
Beaver Lodge, Antelope, and Blue Buttes fields were all highlighted by high lightning density. He did not even point out the Sanish Field. The question then was if this
response is just because of the drilling pipes in the fields. We looked at the density and patterns of lightning strikes over the Beaver Lodge Field, which is the most
densely drilled field on the Nesson anticline, and compared it to similar areas 50 miles to the east and the west. The same density and patterns of lightning strikes occur
at each site. Our conclusion is that the rock matrix has much more to do with the electrical earth currents driving lightning strike location than the drilling pipes.
