Trillium Compact Exploration
The Trillium Compact Exploration is specifically tuned for frequencies below 10Hz: ideal for low frequency seismic surveys designed to identify hydrocarbon reserves or the continuous low frequency monitoring of hydro-frac operations. The Trillium Compact Exploration features an ultra-low noise floor and 20s corner frequency.
The Trillium Compact Exploration has been designed for rapid and repeated deployments. Ease of use features include:
- 10° of leveling freedom: place sensor and go
- Integrated mounting options for an array of terrain types
- Available exploration kit includes solar panel, battery and digitizer with integrated recorder.
- Research grade instrument capable of performing low frequency surveys in any environment
- Rapidly deployable instrument requires no leveling below 10°
- Companion digitizer with recorder eliminates the need for wire-line installations and associated site preparation.
