The GEO-T 20 GT is a truck-mounted rig developed for high-productivity water well and geothermal dual-head drilling applications requiring increased mobility and fast job site transfer between drilling locations.
The GEO-T 20 GT combines high pullback capacity, powerful hydraulic performance and advanced dual-head drilling technology within a highly mobile truck-mounted configuration. Installed on 4x4, 6x4 or 6x6 carrier trucks, typically on two- or three-axle chassis depending on customer requirements and local road regulations, the rig provides excellent operational flexibility and rapid mobilization capabilities. Its dual-head system enables simultaneous drilling and casing, ensuring continuous borehole support, improved drilling stability and efficient cuttings evacuation during drilling operations. Like the crawler-mounted GT models, the GEO-T 20 GT can be equipped with a wide range of geothermal and water well drilling accessories, including diverter systems for cuttings management and high-capacity flushing pumps.
