Cold-Atom Gravimetry for resource exploration and monitoring

Our |g| (absolute g) system is the world’s first quantum absolute gravimeter engineered for field survey operations. With drift-free, absolute gravity measurements based on cold-atom interferometry, our technology eliminates the need for repeated calibration or lengthy post-processing. You gain consistent, reliable data from day one, enabling faster, more confident decisions in exploration and resource monitoring.Our gravimeter delivers advanced gravity survey capabilities for multiple applications: (1) Exploration surveys: Detect density anomalies and subsurface structures for early-stage resource identification with minimal outcrop exposure or challenging terrain, improving drilling accuracy and reduces unnecessary drilling costs. (2) Carbon Capture and Storage: Track subtle changes in subsurface density to verify CO₂ storage integrity, identify potential leakage pathways, and support long-term site compliance. (3) Groundwater: Provide high-resolution gravity data to assess changes in groundwater levels, aquifer dynamics, or recharge trends. (4) Reduced Re-survey and Calibration Costs: traditional relative gravimeters drift over time, requiring frequent re-calibration. Since our cold-atom sensors are absolute gravimeters and effectively drift-free, this eliminates those repeated baseline measurements and saving both time and money in the field.

Value proposition

|g| delivers absolute and drift-free gravimetry in a field-ready form factor

Bottleneck of SOTA

Traditional gravimeters are either compact & field-ready spring-gravimeters but sensitive to shocks, drift & need frequent re-calibration, or bulky and sensitive devices not suitable for the field. Absolute gravimetry combines those advantages by being calibration-free & offering uGal level accuracy
