Abstract
A geothermal well has been drilled at the St. Mary's Hospital in Pierre, South Dakota. The well is 2176 feet deep and artesian flows 375 gpm at 106°F. The well is producing fluids from the Mississippian Madison Group, a sequence of carbonate rocks deposited over several western states. The project was funded by the Department of Energy to demonstrate the geothermal potential of this widespread aquifer. This case study describes the development of the project through geology, drilling, stimulation, and testing.
