A city-wide geothermal space heating project is currently under development at Klamath Falls, Oregon. The first phase of the project will require two production wells. Geothermally heated water will be used to heat 14 city, county, state, and federal buildings. At peak load the heating system will require approximately 750 gpm of 200{sup 0}F (or greater) geothermal brine. The first production well was spudded on August 29, 1979. During drilling a major lost circulation zone was encountered between 340 and 360 ft depth. At this time the well was cleaned, reamed, cased to 300 ft, and then pump tested. The well was pumped for a total of 15 1/2 hr. A maximum flow rate of 680, with 77 ft of drawdown, was held constant for 7 1/2 hr. Discharge temperature was approximately 218{sup 0}F. Three observation wells were monitored to determine the impact of producing large quantities of brine on the many private geothermal wells already in use for space heating. Preliminary indications are that the water level decline in the area will be small (2 to 3 ft). However, further testing is recommended to determine the effects of reservoir heterogeneity on the water level decline.
