Tremornet is sold and marketed as Quantum.
Tremornet pushes the boundaries in wireless seismic sensor networks for on-shore oil & gas exploration and monitoring. Its ultra-low power technology means that each sensor node is significantly smaller and easier to handle, without compromising on sensing performance. This makes deployment and maintenance of large sensor networks simpler, faster and more cost efficient than cabled or other wireless systems.
Designed to scale up to million node networks, Tremornet allows for higher resolution imaging and wide azimuth geometries. It also provides increased topology freedom for various terrains across large survey areas.
Tremornet is available with Bluetooth quality control functions for in-field QC and configuration when required. This ensures consistent data quality and eliminates rework.
Our systems offer high signal fidelity, autonomous data recording with position and time stamping through GPS functionality, to enable accurate off-line data collection.
Features and Benefits
Each node weighs just 650 grams, including battery and weather-proof housing. As a result transportation and deployment costs can be significantly reduced.
Lasting 50+ days in continuous recording mode and 100 days on 12 hr/day Tremornet has the longest battery life allowing improved operational efficiency and peace of mind.
Tremornet has the industry’s largest nodal instantaneous dynamic range. This means improved signal-to-noise ratios.
Our nodes are highly reliable and function entirely autonomously including automated sensor testing. However, if infield quality control is required this can be done using a low-power Bluetooth connection.
Easily deployable nodes without the hassle of cables or external batteries allows for operational efficiencies in all terrains and varying topologies. No disassembly required for charging and harvesting. Portable data harvesting solutions for quick in-field retrieval of data.
Smaller crews with less weight to transport and with less heavy equipment on-site result in lower HSE exposure. Fewer batteries mean less impact on the environment.

Harvesting, charging and data management
We understand the importance of quickly and easily delivery high-quality seismic data in the format required by the end users.
Docking stations for data harvesting of the nodes are available in 19 inch rack, as well as roto-shock portable configurations. Portable docking stations can be used in the field to extract data. High data transfer rates means the full 8 GB of data is retrieved in roughly 10 minutes, in parallel from all nodes. If the nodes needs to be charged, they will charge from completely empty in 3 hours. Software provides overviews of the harvesting and charging statuses and an inventory of nodes and data.
