Exploration Activity: Thermal Gradient Holes At Hualalai Northwest Rift Area (Thomas, 1986)

Exploration Activity Details
Location	Hualalai Northwest Rift Area
Exploration Technique	Thermal Gradient Holes
Activity Date
Usefulness	not useful
DOE-funding	Unknown

Notes

Although not part of the current effort, two deep (approximately 2000 m) exploratory wells were drilled on the north flank of Hualalai near Puu Waawaa cinder cone. The geophysical data used for siting these wells were proprietary and hence unavailable for publication; however, the temperatures measured at the bottoms of the wells were reported to be below 20degrees C. Chemical analysis of water samples taken from these wells did not provide useful geothermal data due to contamination of the well water with drilling muds
