Journal Article: Understanding The Chena Hot Springs, Alaska, Geothermal System Using Temperature And Pressure Data From Exploration Boreholes

Abstract
Chena Hot Springs is a small, moderate temperature, deep circulating geothermal system, apparently typical of those associated to hot springs of interior Alaska. Multi-stage drilling was used in some exploration boreholes and was found to be useful for understanding subsurface flow characteristics and developing a conceptual model of the system. The results illustrate how temperature profiles illuminate varying pressure versus depth characteristics and can be used alone in cases where staged drilling is not practical. The extensive exploration activities helped define optimal fluid production and injection areas, and showed that the system could provide sufficient hot fluids (~57°C) to run a 400-kWe binary power plant, which came on line in 2006.
