GLADE Project: Pre-Feasibility Economic Evaluation by National Lab of the Rockies
The Geothermal Limitless Approach to Drilling Efficiencies (GLADE) project was undertaken in Denver-Julesburg (DJ) Basin Colorado to evaluate whether advanced oil and gas drilling practices could be adapted to improve geothermal well construction in deep, hot, hard-rock environments. Funded by the U.S. Department of Energy Geothermal Technologies Office and executed by Oxy, the project focused on drilling two deep wells, GLADE West and GLADE East, through the sedimentary section and into Precambrian granitic basement. The file contains a Pre-Feasibility Economic Evaluation for the DJ Basin, Colorado incorporating GLADE drilling results.
This work was authored by the National Laboratory of the Rockies for the U.S. Department of Energy (DOE), operated under Contract No. DE-AC36-08GO28308.
