Geothermal energy uses the earth's thermal energy generated and stored in the earth's geology from the core to the surface. Steam, hot water and minerals are some of the most important direct products of geothermal resources.
Geothermal drilling is used to access this stored energy through a process of creating boreholes in the earth to extract the earth's heat.
Geothermal well profiles are characterized as challenging.
Geothermal energy uses the earth’s thermal energy generated and stored in the earth’s geology from the core to the surface. Steam, hot water and minerals are some of the most important direct products of geothermal resources. Convenient access to this energy source is concentrated at the margins of the earth’s tectonic plates where conventional drilling techniques and equipment can best be exploited. Geothermal drilling is used to access this stored energy through a process of creating boreholes in the earth to extract the earth’s heat.
Most of today’s geothermal drilling projects are located in continental Europe, the Philippines, Indonesia, New Zealand, and the Americas.
Geothermal well profiles are characterized as challenging. Hydrogen sulphide, high torsion, high temperatures and punishing wear are a few of the extreme conditions, which may be experienced during geothermal drilling. The extremely hard and abrasive rock formations found in geothermal wells result in torsion levels and equipment wear which may be higher than those found in oil and gas drilling.
