Exploration Basis
Determine field hydraulic conductivity using borehole impeller flowmeter data
A quantitative evaluation of borehole-impeller flowmeter data leads to estimated field hydraulic conductivity. Data were obtained during an injection test of a geothermal well at the Raft River geothermal test site in Idaho. Both stationary and trolling calibrations of the flowmeter were made in the well. Methods were developed to adjust for variations in hole diameter, impeller speed, and trolling speed. These methods were applied to evaluate water losses into the formation as a function of depth.The flowmeter data were digitized and processed by the computer to obtain plots of apparent field hydraulic conductivity versus depth.
