Journal Article: Geothermal Prospecting In Shallow Holes And Its Limitations

Abstract
Reproducibility of temperature measurement considerably limits the sensitivity and economy (holes depth) of geothermal investigations. From the point of view of the attainable accuracy and reproducibility, error sources on the instrumental part and on the temperature field itself are analysed. The instrumentation conception and technique are considered to indicate the contemporary technical possibilities. As the best solution to field conditions the thermistor thermometer is shown. The design of a Czechoslovak geothermometer GT-1 with reproducibility better than 0.04 deg centigrade is comprehensively described. Some possibilities of methodical improvements in geothermal prospection in shallow holes, such as the gradient method, standard points method and long term variation corrections, are dealt with. Some example of use and prospection experience in hydrogeological, sulfidic ores and speleological investigations are given.
