HammerDrum - Innovative Deep Geothermal Drilling Machine

SHARE

HammerDrum develops compact, electrically-operated drilling technology for deep geothermal drilling, aimed at significantly reducing construction site space and operational costs. The technology consists of a 6-meter-long drill that is directly lowered into boreholes via a steel cable. Once at the bottom, it secures itself with a gripper and uses a striking rotational mechanism to drill predefined sections. The drill collects cuttings during the process and transports them back to the surface for removal, allowing it to be prepared for subsequent drilling cycles. To enhance efficiency and minimize downtime, multiple machines can be deployed sequentially. Simulation trials indicate a descent and ascent speed of around 15 km/h and a drilling rate of approximately 5 cm per minute, enabling the completion of a 1 km well within 3 to 4 weeks. Surface operations are housed within a standard TEU container, fitting within two parking spaces, and are fully automated for continuous operation. This innovative approach promises to reduce deep drilling costs by up to 80%, making it suitable for urban environments where space is a premium.

100X Smaller

We are developing a drilling technology that reduces the size of the construction site by a factor of 100 compared to conventional deep drilling rigs, thereby enabling deep drilling in urban areas.

5X Cheaper

By simplifying the process and a high degree of automation, we can massively reduce the costs of deep drilling by up to 80%

An innovative drilling machine designed for deployment within boreholes has been developed, integrating advanced technologies to enable fully automated drilling. Unlike traditional methods operated from the surface, this compact machine facilitates highly automated operations within confined spaces.

This 6-meter-long, electrically operated drill is lowered directly into the borehole via a steel cable. Upon reaching the bottom, the machine secures itself with a gripper and employs a striking rotation mechanism to drill predefined sections.

Cuttings are collected during batch drilling and transported back to the surface upon completion. The drill is then emptied and prepared for the next cycle. To minimize downtime, a second machine can be deployed immediately after the first is retrieved.

Simulations demonstrate that the drill can achieve ascent and descent speeds of approximately 15 km/h, with a drilling progress rate of around 5 cm per minute. Based on these parameters, a 1 km well can be completed within 3 to 4 weeks.

Surface operations are automated and can be accommodated within a standard container (TEU), allowing drilling activities to be conducted in an area approximately the size of two parking spaces. This automation ensures continuous and efficient drilling, comparable to the operation of a robotic lawn mower.
