Chemical logging: a geothermal technique
Chemical logging studies conducted at the Department of Energy's Raft River Geothermal Test Site in south central Idaho resulted in the development of a technique to assist in geothermal well drilling and resource development. Calcium-alkalinity ratios plotted versus drill depth assisted in defining warm and hot water aquifers. Correlations between the calcium-alkalinity log and lithologic logs were used to determine aquifer types and detection of hot water zones 15 to 120 m before drill penetration. INEL-1 at the Idaho National Engineering Laboratory site in eastern Idaho represents the second area where this was applied. Calcium-alkalinity ratio, lithologic, and compensated neutron logs correlated well and were used to define the water-producing zones penetrated by the well. This well is located in an area of different geologic and hydrologic characteristics.
