Geothermal Drilling
Geothermal drilling involves the process of creating boreholes that access the heat stored beneath the surface. By reaching depths where temperatures are high enough, this technique allows for the extraction of steam or hot water, which can
then be used to generate electricity or provide direct heating.
Drilling Techniques
Various drilling techniques are employed in geothermal projects, tailored to the specific geological conditions and resource types.
Some of the most common methods include:
-
Rotary Drilling/Open Holing
-
DTH Hammer Drilling
The choice of drilling technique is influenced by factors such as:
-
Depth of the resource
-
Geological characteristics
