Geothermal exploration is the bridge between early-stage ideas for geothermal development and fully committed planning and start-up of geothermal production.  In the broadest sense, geothermal exploration involves proving the viability of geothermal energy as a practical means of generating power and/or heat in a particular location.  The knowledge obtained through exploration is the basis for an assessment of energy-producing potential and the subsequent creation of engineering plans and construction cost estimates.  The quality of the assessment depends on the quality of the available data.

Accurate information from the exploration stage is crucial to assess not only the overall viability of energy production but the detailed physical challenges of drilling, operational expectations and costs.
