Geothermal wells: CCTV Surveys and Borehole Logging


Geothermal wells are an expensive part of any geothermal development, so data is essential for construction, development and on-going maintenance. European Geophysical Services has experience working on deep geothermal projects and open and closed loop systems.

Open Loop


An open loop geothermal system relies on two wells (one supply and one return) to pipe clean ground water directly from a nearby aquifier to an indoor geothermal heat pump. Open loop is only practical when there is adequate supply of clean ground water.

Closed Loop


A closed loop geothermal system continuously circulates a heat transfer solution in a completely closed loop of plastic piping.
