High precision temperature measurements allow establishing accurate 
temperature logs and characterizing geological events in geothermal wells 
(localization of geological change or of water flow from rocks fractures). In the 
framework of the European HITI project, BRGM wants to transfer his experience 
from low temperature domain (0-130 °C) to high temperature domain (up to 
320 °C).
Proposed wireline logging tool aim an accuracy better than 0.1°C and a 
sensitivity better than 0.005°C in a range of 0 to 320°C.
