Fracking in the Bracken Formation

We stopped overnight in Williston, North Dakota.  It is the North Dakota hub for all the fracking activity in the Bracken formation.....remember Lac Megantic? This is where all the explosive oil originated.....and Bev is adding that there at 20 men for every woman in Williston (they are all loaded and they drink too much).  Dave adds that there are 20 pickups for every car!!
We followed Rte 1804 along the north shore of the Missouri River; this is also the main supply route to the fracking operations which are about every 1/4 mile along the road.  Each of the wells consisted of numerous tanks for holding the liquids they inject into the formation, a walking arm pump that pumps the oil out of the ground and into a network of pipelines that parallel the highway and finally a flare to burn off the hydrogen sulfide gas.  It is this hydrogen sulfide gas that is mixed with the oil that is thought to make the bracken crude so explosive.
