3C Seismic Node For Geothermal Exploration
Features for our seismic node
A low-cost and portable seismic node system, capable of managing, charging and harvesting data from up to 30,000 nodes in field. The 3C Seismic Node system has enabled increased productivity, rapid delivery, reduced HSE risk and ease of use while delivering higher-quality results for subsurface imaging.
Ideal item for deep geothermal exploration, and light enough for one person to carry.Cheap enough that we can be very competitive and win more work in particular in the geothermal sector, and with a high accuracy equivalent or superior to other systems.
Application
1. Geothermal exploration
2. CCUS exploration and monitoring,
3. Mining,
4. Archaeology,
5. Civil engineering,
6. Oil & gas,
7. Seismic risk,
8. Passive seismic and microseismic.
