Quantify What You See. Strengthen Every Emissions Decision.
Flir pioneered Optical Gas Imaging and continues to advance emissions monitoring through Quantitative OGI (QOGI). Use this resource hub to explore the workflows, validation studies, training resources, and technical guidance needed to confidently detect, quantify, and prioritize fugitive emissions in the field.
QOGI extends traditional OGI by adding an in-camera estimate of emission rate, giving operators more context behind every leak they detect.
It provides rapid, decision-ready measurements that fit directly into existing Leak Detection and Repair (LDAR), Measurement-Reporting-Verification (MRV), and reporting workflows.

Why QOGI Matters
Strengthening emissions reporting and regulatory compliance.
Improving LDAR programs through smarter measurement.
Improving safety and operations in difficult-to-access areas.
Moving from LDAR to LDAQ with quantitative optical gas imaging.
Proven performance backed by peer-reviewed studies and real-world validation.
QOGI supports methane-reduction and emissions-management workflows across a wide range of industries—including oil and gas, petrochemical processing, power generation, food and beverage, insurance, and commercial facilities.
From upstream and midstream operations to regulated inspections, ESG reporting, and loss mitigation, QOGI delivers fast, actionable insights for leak detection, compliance, and operational efficiency in both industrial and commercial environments.

QOGI empowers you to measure and quantify hydrocarbon, including methane, and VOC gas leaks directly from specialized thermal images, delivering actionable emission estimates for visible plumes in real-world conditions. It’s ideal for identifying and sizing leaks that matter most to your operations, even in hard-to-reach or hazardous areas. For ultra-trace or laboratory-level analysis, QOGI complements traditional tools by providing rapid, field-ready results that drive faster decisions.
QOGI delivers reliable, repeatable quantification when used within its recommended operating envelope. Proven successful in validated 3rd party studies, FLIR’s advanced algorithms and camera features help minimize uncertainty, and results are presented with clear confidence intervals so you can trust your data. From increased accuracy with aggregate emissions measurements to transparent uncertainty displayed with every measurement, QOGI provides the accuracy needed for emissions management, reporting, and compliance with proper setup and workflow.
Choose QOGI when you want to maximize efficiency, safety, and coverage—especially for large facilities, elevated components, or areas where direct access is difficult or risky. QOGI enables rapid, non-contact quantification, allowing you to prioritize repairs and document emissions without interrupting operations. It’s the go-to solution for modern LDAR, MRV, and compliance-driven workflows.
Like all technologies, environmental conditions can play a key role into proper use, implementation in real-world field environments and results.
While factors like wind, temperature, and background can influence results, FLIR cameras are designed with features that help you adapt and optimize measurements. Following best practices and understanding the technology ensures you get consistent, high-quality data—even in challenging conditions.
QOGI is a game-changer for emissions management. It streamlines LDAR by combining detection and quantification in a single workflow, supports MRV and OGMP 2.0 programs with measurement-based reporting, and helps you meet regulatory requirements with confidence. QOGI’s flexibility and speed make it an essential tool for any emissions-reduction strategy.
The most common mistakes are easily avoided with FLIR’s proven guidance: ensure stable camera setup, maintain optimal distance and angle, and pay attention to environmental factors. FLIR provides comprehensive training and intuitive camera features to help every user achieve expert-level results, minimizing errors, and maximizing the value of your QOGI investment.
