Geothermal Generation - Slim Well, F. E. Warren AFB, Wyoming   4

Background
The F. E. Warren Geothermal Generation Project is a comprehensive initiative aimed at exploring and characterizing the presence and productivity of geothermal resources at F. E. Warren AFB, located east of Cheyenne, Wyoming. The project is focused on drilling a geothermal well to measure the thickness and test the properties of the Hartville Formation, along with underlying formations such as the Guernsey, Flathead, and Pre-Cambrian Formations.

The goal is to gather data that will determine if conditions exist to support a geothermal power plant. The estimated construction cost for this project ranges from $10,000,000 to $25,000,000.
