DNR helps log and explore state’s geothermal energy potential

Geothermal geologists log well

Even it requires a bumpy 3-hour Snowcat ride each way, geothermal geologists are willing to go where the geothermal is… or might be. Geothermal geologist Jeff Bowman (from DNR) and Adam Lewis (from Snohomish County PUD) spent several chilly days logging an exploration well for temperature gradients that might reveal the underlying formation’s geothermal energy potential. The geologists worked with the site’s private landowner in March 2011 to log the well, which is near Garland Hot Springs in Snohomish County.

Exploratory geothermal well logging is an important element of DNR’s work, and occurs statewide on state and other public lands as well as on private lands with the landowner’s permission. DNR is conducting the well logging—making a detailed record of geologic formations penetrated by a borehole—with funds from a National Geothermal Data System grant issued by the U.S. Dept. of Energy.
