Geothermal Division Drilling of exploratory wells as the final phase of any geothermal exploration program is the only means of determining the real characteristics of the geothermal reservoir and, thus, of assessing its potential. The data provided by exploratory wells should be capable of verifying all hypotheses and models elaborated from the results of surface exploration and of confirming that the reservoir is productive. Leutert downhole tools deliver such data. By adjusting our tools to the very specific requirements found within Geothermal Systems, Leutert helps to close the gap between the geothermal and the oil industry. This way, parallel developments may be avoided reducing the exploration costs of our customers. As an example the Leutert Positive or Controlled Displacement Sampler can be used to collect wellbore fluid samples from the well, which has several feed-zones, and to clarify the chemical differences in each feed zone. Operated in combination with a Leutert Memory Gauge, the potential of each feed zone may be determined. For product details, please see the oil & gas division.
