Temperature measurement data obtained from boreholes for the Association of American State Geologists (AASG) geothermal data project. Typically bottomhole temperatures are recorded from log headers, and this information is provided through a borehole temperature observation service for each state. Service includes header records, well logs, temperature measurements, and other information for each borehole. Information presented in Geothermal Prospector was derived from data aggregated from the borehole temperature observations for all states. For each observation, the given well location was recorded and the best available well identifier (name), temperature and depth were chosen. The "Well Name Source," "Temp. Type" and "Depth Type" attributes indicate the field used from the original service. This data was then cleaned and converted to consistent units. The accuracy of the observation's location, name, temperature or depth was note assessed beyond that originally provided by the service. Bottom hole temperature datasets from the AASG were downloaded from repository.usgin.org between May 16 and May 24, 2013. The data were cleaned to remove null and non-real entries, and units were standardized across all datasets. When selecting key attributes, specific criteria were used to determine the best available values. For temperature, corrected temperature was preferred, followed by measured temperature. For depth, depth of measurement was prioritized, with true vertical depth and driller total depth used as alternatives. Well identification was assigned based on the API number when available, followed by the well name, with the observation URI used as a last option.
