Diagenesis and fracture development in the Bakken Formation, Williston Basin: Implications for reservoir quality in the middle member
Janet K. Pitman, Leigh C. Price, Julie A. LeFever
2001, Professional Paper 1653
The middle member of the Bakken Formation is an attractive petroleum exploration target in the deeper part of the Williston Basin because it is favorably positioned with respect to source and seal units. Progressive rates of burial and minor uplift and erosion of this member led to a stable thermal...

A simple calculator of ballistic trajectories for blocks ejected during volcanic eruptions
Larry G. Mastin
2001, Open-File Report 2001-45
During the past century, numerous observers have described the violent ejection of large blocks and bombs from volcanoes during volcanic explosions. Minakami (1942) mapped the locations of blocks ejected from Asama Volcano during explosions in 1937. He developed a mathematical expression relating initial velocity and trajectory angle of ejected blocks...
