| Abstract | An innovative system for temperature and pressure measurements in geothermal wells is described. It was developed by ENEL and CISE with the aim to operate contemporary and real-time well logging. The system, named HELIUM 48 (Hostile Environment Light Instrumentation for Underground Measurements), can also be used inside of the drilling rods. It is based on a suitable "HostEn" (Hostile Environment) seven conductors cable in order to fulfil the following operating conditions: maximum depth: 4000 m maximum pressure: 50 maximum temperature: 400 No dewar nor other thermal shiels are employed for the probe; so it hasn't any time limit for its in-well work. The technical features of the main components of this high performant and system are described and the operation results are reported. |
