BRINGING LIGHT TO DARK BOREHOLES
Even without extracting their cores, boreholes can reveal a vast amount of information thanks to ever more sophisticated borehole measuring methods known as 'logs'. We have a logger with a 2,000 m logging cable with which to perform borehole measurements. For lithological documentation (rock parameters), a combination of gamma ray logging and resistivity logging can be used. The caliper log supplies information about the general condition of the borehole and enables the volume of the borehole to be calculated.
For more advanced hydrogeological tasks, we carry out fluid loggings (temperature, conductivity and flowmeter) to record inflow and outflow rates.
