What are some of the difficulties of drilling in the Bakken Formation?

Traditional oil fields extract oil from rocks with relatively high porosity and permeability, so the oil flows out fairly easily. In contrast, the Bakken Formation is a relatively tight formation with low porosity and low permeability rock, from which oil flows with difficulty. To overcome this problem, wells in the Bakken Formation use a method called hydraulic fracturing (aka fracking) in which water and other materials (like sand) are pumped downhole at high pressure to create open fractures and artificial permeability. The oil can then flow more easily out of these fractures and tight pores.
