Case Study: Advancing Seismic Imaging in Complex Geology

Steeply dipping layers and strong lateral velocity variations remain a major challenge in geophysical exploration. A recent study proposed an initial-model-constrained joint Kirchhoff prestack depth and time migration method — integrating iterative velocity inversion, denoising, and model constraints to improve imaging fidelity and repeatability.

📍 Key results:
Sharper fault imaging and better diffraction focusing
Higher signal-to-noise ratio (S/N) and improved resolution versus conventional prestack time migration
Validated on both synthetic models and a real coalfield case (monocline 30–35°, high-angle faults)
Field data were acquired using SmartSolo IGU-BD3C-5 broadband 3-component nodal seismometers — 720 channels, 10 m × 10 m CDP grid, max fold 52.
The method has been applied in coal mine safety, resource exploration, engineering investigation, and geohazard assessment.

♨️ Case Study: Passive Seismic Microtremor Survey for Geothermal Exploration

Regional fault activity and multi-stage magmatism are key drivers for the formation of mid-to-low temperature geothermal resources. To identify deep hidden faults within a geothermal field, we deployed a linear array of 48 SmartSolo IGU-BD3C-5 nodes at 150-m station spacing for Microtremor Survey.

Key Findings:
✅ Velocity Anomalies: The 2D inversion revealed a distinct low-velocity anomaly between survey stations 3000-7050, which was interpreted as a fault zone.
✅ Fault Identification: Integrated with Magnetotelluric (MT) results and two boreholes (ZK1: 500m, ZK2: 600m), three secondary faults (F1, F2, F3) were confidently identified and constrained.
✅ Fracture Detection: String-like low-velocity anomalies at stations 8250 and 9450 were inferred as stratigraphic fractures.

Conclusion:
The microtremor survey successfully mapped the regional fault distribution, providing a solid geophysical basis for further geological exploration and geothermal well planning.

📡Case Study: Using Ambient Noise Tomography (ANT) to Detect Hidden Dam Fractures

Excavation caused slight displacement in a dam body. Surface cracks were visible, but the internal structural integrity remained unclear—could hidden seepage channels be developing beneath the surface?

The Solution: We deployed a dense SmartSolo array to conduct Ambient Noise Tomography (ANT) and invert S-wave velocity structures across the dam.

Key Findings:
✅ Line 1: The front section (0-100m) exhibited distinct low-velocity zones, clearly mapping the excavation disturbance. The rear section remained intact (>1000 m/s).
✅ Line 3: Revealed a buried through-going fracture zone at the dam's top boundary (30-60m), identified as a significant risk area.
✅ Line 4: Detected a thin surficial soil layer (350-450 m/s) and a notable tensile stress zone. We identified hidden interconnected fracture networks (white lines) that act as primary water seepage pathways.

Conclusion: While surface monitoring captures only what is visible, ANT delivers an "X-ray" view of the dam's internal stress state, providing actionable insights for slope reinforcement.

🏢 Case Study: High-Fidelity SHM of a 21-Story High-Rise Building

Traditional structural-health-monitoring (SHM) often faces challenges balancing precise damage localization with real-time monitoring. Our solution combines Seismic Ambient Noise (SAN) with machine-learning algorithms and has been validated on a 21-story building in Shanghai.

Setup: 22 SmartSolo IGU-16HR 3C nodes were deployed floor-by-floor (from the basement to the 21st floor) + 2 ground stations. The instruments continuously recorded data at a sampling rate of 250 Hz over a 22-day campaign, successfully capturing two Beaufort Wind Force 8-9 strong-wind events.

Key Results:
✅ Captured non-uniform stiffness distribution (frequencies 0.38–0.45Hz) under strong wind.
✅ Precisely localized an approximate 2% reduction in wave velocity between F6-F7 and F9-F10, marking zones of stress concentration.

Conclusion: All 24 units performed flawlessly for 22 days. This confirms the technical feasibility of dense nodal arrays for building SHM, proving SmartSolo's exceptional stability and high-resolution measurement performance within complex urban environments.

Harnessing Ambient Noise for Transparent Mining – A SmartSolo Success Story

💻 In the pursuit of smarter and safer mining processes, accurate characterization of underground strata continues to be a core challenge. Traditional methods like boreholes or GPR are often point-based, inefficient in wet conditions, and disruptive to operations.

📝 A recent project at a limestone mine tackled this head-on. Instead of using active seismic sources, the team leveraged ambient noise from machinery and vehicle movement.

📍 The Setup
A linear array of 120 SmartSolo IGU-16HR 5Hz nodal seismometers was deployed at 1-meter spacing. Using single-station autocorrelation and spatial autocorrelation (S**C), the team successfully imaged the subsurface down to 25 meters.

🔎 The Results
💡 High-resolution images identified three low-velocity anomalies corresponding to voids or loose zones.
💡 Subsequent targeted drilling confirmed the seismic interpretations.
💡 SmartSolo data quality was critical to generating clear velocity models.

This study shows that high-density ambient noise seismic imaging is a game-changer for open-pit mining—fast, accurate, and non-intrusive. SmartSolo nodal systems proved essential in delivering the reliable data needed for safer, more efficient mining operations.

📍 Manas Anticline 3D Project – Survey Complete

💻 The Manas Anticline 3D seismic survey has reached a key milestone: all survey stakeout activities have been successfully completed, with 390,000 receiver points and 150,000 source points fully staked and established in accordance with strict technical specifications.

📝 The project spans 1,400 km² across complex terrain, comprising approximately 30% mountainous areas, 25% farmland and urban areas, and 33% Gobi pasture, all within a tight ex*****on schedule. The team mobilized 38 survey crews and implemented adaptive field strategies in real time: mountain teams operated under safety-first protocols, rapid-response units were deployed in sensitive areas, and additional field personnel were mobilized during the spring planting season to prevent nodes from being buried during agricultural activities.

🎖️ SmartSolo nodal seismic systems played a critical role throughout the survey. Their lightweight, cable-free design and scalable deployment enabled rapid rollout across challenging terrain, helping keep the acquisition on track even under tight deadlines.
