Geothermal heat response test
http://www.geothermal-energy.org/pdf/IGAstandard/WGC/2005/1436.pdf WebA useful tool to do so is a thermal response test, carried out on a BHE in a pilot borehole (later to be part of the borehole field). For a thermal response test, basically a defined heat load is put into the hole and the resulting temperature changes of the circulating fluid are measured. Since late 1990s, this technology became more and more
