Abstract
The three successful deep wells in Raft River have tapped a 300°F reservoir. The wells are artesian, but their use dictates pumping to achieve the maximum production rates. Well performance and production rates over many years indicate about 2 MW (e) per well using the binary cycle is predicted, and this at only 12% thermal efficiency. Use for non-electric direct heat represents 16 MW/well over the long term. Drilling technique and methods of determining the resource presence so as not to case it off have been the keys to getting the maximum production from these wells. Three channels in the bottom of the third well increased its production 5 times compared t one channel.
