GEOTHERMAL
GEOTHERMAL APPLICATION
Geothermal energy is heat generated and stored in the earth, from the core to the surface. Steam, hot water and minerals are its most important direct products. Geothermal drilling creates boreholes to bring this heat to the surface, and geothermal wells are challenging to drill.
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. This energy is easiest to reach at the edges of the earth’s tectonic plates, where conventional drilling techniques and equipment work best. 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 sulfide, high torque, high temperatures and punishing wear are some of the extreme conditions met in geothermal drilling. The very hard, abrasive rock can cause higher torque and equipment wear than in oil and gas drilling.
Products & Solutions
Command Tubular Products offers custom drill strings to meet geothermal challenges head-on:
- High-performance connections: high-torque double-shoulder connections on request
- Hardbanding: a hard, highly abrasion-resistant sacrificial layer applied to tool joints and wear pads. We offer alloy steel and tungsten carbide hardbanding, from our own proprietary products and specialist manufacturers, to suit the drilling conditions and each customer's requirements.
