Bachelor of Science in Geological Engineering
Mr. John B. Flugstad
The Ragged Point oil field is located in Northwest Musselshell County, in the Lake Basin field of central Montana, and on the western border of the Great Plains region. The surface topography is that of a plain marked by erosion and moderate folding. The stratigraphy of central Montana shows periodic marine invasions from the Cordilleran trough, with normal marine limestones interbedded with sandstone sand shales. These sediments are over 12,000 feet thick, with the Cretaceous Eagle and Colorado formations exposed at the surface on the Ragged Point anticline. Undifferentiated Cambrian limestones and shales are the oldest rocks encountered in drilling.
