As part of our efforts to disseminate legacy data and preserve the history of geothermal energy in Hawaii, we made an information page about the Scientific Observation Hole (SOH):

A geothermal experiment proved that the Kilauea East Rift Zone held geothermal potential. From 1990 to 1991, the Scientific Observation Hole (SOH) program operated three geothermal test wells in Puna, Hawaii. The data showed that a ten-mile interval along the Kilauea East Rift Zone held favorable high temperatures.

This page contains a brief history of SOH and links to relevant reports and data.
