Advanced Sensing for
Oil & Gas Infrastructure
Sensorlines fiber optic sensing protects upstream, midstream, and downstream oil & gas assets — detecting leaks, intrusion, and structural anomalies across hundreds of kilometers from a single interrogator unit.
Oil & Gas Pipeline Monitoring
Sensorlines deploys DAS and DTS sensing along oil transmission and distribution pipelines — transforming a standard fiber optic cable co-located alongside the pipeline into a real-time, continuous monitoring system covering hundreds of kilometers from a single interrogator.
How It Works
A dedicated sensing fiber is installed alongside the pipeline in the same trench. DAS detects the acoustic pressure waves generated by fluid escaping a leak, classifying the event within seconds and locating it to within ±10 m. DTS maps ground temperature anomalies indicating product seepage, hot-fluid leaks, or flow assurance issues such as wax plug formation.
Key Capabilities
- Real-time leak detection with ±10 m location accuracy over 100 km
- Third-party interference (TPI) alerts — digging, drilling, heavy machinery near RoW
- Ground movement and landslide detection via distributed acoustic sensing
- Flow assurance monitoring — wax plug, hydrate formation, slug detection
- Hot tap and pig detection for operational awareness
- SCADA integration and regulatory compliance reporting
Oil & Gas Storage Tank Monitoring
Distributed Temperature Sensing wrapped around tank shells provides continuous thermal mapping of fuel storage tanks, chemical storage vessels, and floating roof tanks — detecting leaks, product stratification, and fire hazards before they escalate into catastrophic events.
How It Works
A sensing fiber cable is wound in a helical pattern around the outer shell of each storage tank at 1–2 m vertical intervals. Each meter of cable acts as an independent temperature sensor. Product seeping through a weld or base plate creates a localised temperature anomaly detectable to 0.1 °C resolution. A concurrent DAS channel monitors for structural impacts, liquid level changes, and vapor cloud events that precede fire or explosion.
Key Capabilities
- Full tank shell temperature mapping at 1 m spatial resolution
- Tank base leak detection via thermal anomaly signature
- Flammable vapor and fire early detection <30 seconds
- Product stratification and interface level monitoring
- Up to 50 tanks monitored from a single interrogator unit
Natural Gas Pipeline Leak Detection & Monitoring
High-sensitivity DAS along natural gas distribution networks detects even micro-leaks within seconds, precisely localising the leak point without any need for ground excavation or manual survey — dramatically reducing explosion risk and methane emissions.
How It Works
A pressure drop at a leak point generates turbulent flow that creates distinctive acoustic energy propagating along the pipe wall and coupling into the sensing fiber. The DAS interrogator performs continuous spectral analysis along the full pipeline length, applying AI-based pattern recognition to discriminate genuine leak signatures from background operational noise. Alerts include GPS-correlated leak location, event classification, and estimated leak severity — fed directly to SCADA and emergency response systems in under 120 seconds.
Key Capabilities
- Micro-leak detection down to 0.5% of pipeline flow rate
- Real-time leak localisation within ±15 m over 80 km
- Regulatory compliance — EPA, BS EN 15001, and international gas codes
- Full SCADA and EMS integration with automated valve closure
- No excavation required — continuous monitoring replaces manual surveys
- Third-party encroachment and illegal tap detection
