AI-Powered Gas Detection & Classification System

What This Document Demonstrates

Our Core Capability: AI That Learns Complex Multi-Sensor Patterns This document presents our validation experiment using commercial gas sensors to prove a fundamental capability: our AI algorithms can learn to detect events (gas leaks) by recognizing subtle, multi-dimensional patterns in time-series sensor data, even when those sensors drift and environmental conditions change.

Why this matters for your SCADA system: Oil and gas leaks don't announce themselves with simple threshold violations. They manifest as complex anomaly patterns across multiple operational parameters—a small pressure drop that wouldn't normally matter, occurring simultaneously with an unexpected temperature shift and a flow rate that's slightly off from what your operational model predicts. These are the multi-parameter patterns our algorithms are designed to detect.

The gas sensor experiment you'll see below proves our algorithms achieve 99.58% accuracy in learning these complex patterns. This same algorithmic approach—when trained on your SCADA operational data—can detect leak signatures from temperature, pressure, and flow anomalies specific to your infrastructure.

The Validation Approach

1. Controlled Experiment
Used 7 commercial gas sensors (MQ2-MQ135) to create a dataset with known gas exposures and sensor drift characteristics. This provides ground truth for algorithm validation.
2. Multi-Sensor Pattern Learning
Trained AI to recognize gas types by analyzing patterns across all sensors simultaneously—not just individual readings—while compensating for sensor drift over time.
3. Safety-Critical Performance
Achieved 99.58% accuracy with only 8 missed detections in 7,680 predictions—demonstrating the algorithm can meet safety-critical requirements where missing events is unacceptable.
4. Transferable Methodology
The same AI framework that learned gas patterns from resistance changes can learn leak patterns from your SCADA operational parameters—it's pattern recognition across time-series data regardless of the underlying physics.

Gas Sensor Experiment: System Overview

Gas Classification
Machine learning models trained with drift characteristics to predict gas types across 4 classes: NoGas, Perfume, Smoke, and Mixture.
Drift Diagnosis
Temporal analysis using ΔR, |ΔR|, and EMA characteristics to detect sensor drift and failures above 15% threshold.
Leak Detection
Threshold-based logic monitoring concentration levels, duration, and rapid changes to identify dangerous leaks.
Automated Alerts
Real-time webhook integration for instant notifications when confirmed leaks or critical drift events are detected.
Important Note

Gas classification and leak detection are independent processes. The system can classify "NoGas" while still detecting a leak if concentration exceeds safety thresholds, or classify "Smoke" without detecting a leak if concentration remains low.

Applying This Capability to Your SCADA System

From Proof-of-Concept to Operational Deployment The gas sensor experiment demonstrates our algorithms work. Now let's discuss how we apply this proven capability to detect leaks in your oil and gas operations using your existing SCADA infrastructure—no new sensors required.

From Gas Sensor Validation to SCADA Leak Detection

Why Gas Sensor Performance Proves Our SCADA Capability

Our 99.58% accuracy on gas sensor data isn't the end goal—it's the proof that our AI algorithms can learn complex, subtle patterns in time-series data. Your SCADA system doesn't have gas sensors; it monitors temperature, pressure, flow rates, and other operational parameters. Our value proposition: if our algorithms can detect gas leaks from resistance patterns, they can detect leaks from operational anomalies in your SCADA data.
Proven Pattern Recognition
Achieving 99.58% accuracy on gas classification demonstrates our algorithms excel at finding subtle patterns in noisy sensor data. Gas sensor resistance changes are complex and non-linear—exactly like the temperature, pressure, and flow anomalies that indicate leaks in pipelines and facilities.
Different Data, Same Principles
Leaks manifest as contextual anomalies in SCADA data: pressure deviations that wouldn't matter alone but signal problems when combined with flow discrepancies and temperature shifts. Small changes in "wrong" circumstances. These multi-dimensional patterns in time-series data are exactly what our algorithms excel at detecting—the same pattern recognition capability proven on gas sensors.
Drift Detection Transfers Directly
Our temporal drift detection methodology (ΔR, |ΔR|, EMA) applies universally to any sensor experiencing baseline shifts over time. SCADA pressure sensors, flow meters, and temperature probes all drift—our algorithms detect and compensate for this regardless of the underlying physics.
Algorithm Validation Without Installation
By proving 99.58% accuracy on a controlled dataset, we demonstrate algorithm maturity before deployment. You don't need to install new sensors—we retrain our proven algorithms on your existing SCADA historical data to detect leak signatures specific to your operations.

The Critical Difference: Operational Data vs. Direct Gas Measurement

Understanding the Detection Approach Your SCADA system monitors operational parameters (temperature, pressure, flow) that change when leaks occur, not gas concentrations directly. A pipeline leak causes pressure drops, flow anomalies, temperature changes, and correlated sensor readings across multiple points. Our AI learns these multi-parameter leak signatures from your historical data—including past incidents—to detect future leaks before they become critical.

From Gas Sensors to SCADA Integration

1
SCADA Data Access & Historical Collection
We connect to your SCADA system via standard industrial protocols (OPC UA, Modbus TCP, MQTT) to access real-time and historical data streams: temperature sensors, pressure transducers, flow meters, valve positions, pump status, and any other operational parameters you monitor.
2
Leak Signature Learning
Using your historical leak events (documented incidents, near-misses, maintenance records), we train our algorithms to recognize the multi-parameter patterns that preceded those events. The AI learns: what does a leak look like in YOUR pressure/temperature/flow data across YOUR specific pipeline configurations?
3
Normal Operations Baseline
We establish normal operational patterns from months of baseline data: typical pressure variations during pumping cycles, expected temperature fluctuations with weather, normal flow rate changes during production adjustments. This baseline allows the AI to distinguish anomalies from normal operations.
4
Algorithm Validation on Historical Data
Before deployment, we test the trained model on historical data you set aside: would our system have detected past leaks? How many false alarms would it have generated during normal operations? This validation phase proves performance before going live.
5
Real-Time Monitoring & Continuous Learning
Once validated, the system monitors your SCADA streams in real-time, comparing current multi-parameter patterns against learned leak signatures. As operators confirm or reject alerts, the system continuously improves its understanding of your facility's unique characteristics.

Realistic Performance Expectations

Performance Targets Expectation: 80-85% accuracy - Based on our models, we expect an accuracy higher than 80%.

Aspirational target: 85-95% accuracy - Achievable with high-quality sensors, comprehensive historical incident data, and optimized model training specific to your facility.

Performance in Context: Our 99.58% Gas Sensor Achievement

Proof of Algorithm Capability The 99.58% accuracy metrics shown throughout this document come from our gas sensor validation work. This proves our algorithms can achieve exceptional performance on complex time-series pattern recognition. When we apply these same algorithms to SCADA operational data for leak detection, we target equivalent performance levels—because the statistical requirements for safety-critical systems remain the same regardless of the sensor type.
8 False Negatives in 7,680 Predictions This translates to a 0.104% miss rate, meaning 99.896% of actual leaks are detected. In industrial terms: if your facility experiences 1,000 leak events per year, our system will catch 999 of them.
8 False Positives in 7,680 Predictions A 0.104% false alarm rate means that for every 1,000 "no leak" conditions, only 1 will trigger a false alarm. This maintains operator trust while ensuring safety vigilance.
Balanced Precision and Recall Both metrics at 99.58% demonstrate the system doesn't trade safety (recall) for convenience (precision) or vice versa. This balance is critical for industrial deployment where both matters.
Consistent Performance Across Gas Types The confusion matrix shows near-perfect classification across all gas classes, meaning the system doesn't have blind spots for specific gases that could create vulnerabilities.
Industry Benchmark Context

Traditional threshold-based leak detection systems in SCADA typically operate at 60-70% accuracy due to inability to distinguish operational changes from actual leaks. AI-based systems that achieve 75-80% are considered state-of-the-art. Our gas sensor validation at 99.58% demonstrates our algorithms have the pattern recognition capability to exceed industry benchmarks—we target 80-85% accuracy when training on SCADA operational data for leak detection.

Our Approach to Your SCADA System

We don't claim your SCADA leak detection will match our 99.58% gas sensor performance—the physics and data are fundamentally different. Instead, we've proven our algorithms CAN achieve exceptional accuracy on complex pattern recognition tasks. When we train on YOUR historical SCADA data—learning YOUR leak signatures from temperature, pressure, and flow patterns—we target 80-85% accuracy, which represents a significant improvement over current industry methods. The validation phase using your historical incidents will demonstrate actual performance before deployment.
