The Challenge of Harsh Environments
Gas emissions detection in harsh environments is one of the most difficult challenges in industrial safety and environmental compliance—especially in oil and gas operations. Sites are often exposed to extreme temperature changes, intense humidity, powerful winds, sand, dust, and corrosive atmospheres. These conditions not only make it more likely for gas leaks to occur but also compromise the performance of conventional gas detection technologies.
In sectors like upstream oil and gas, petrochemicals, and hydrogen infrastructure, operations span deserts, offshore platforms, and remote basins—all characterized by:
- Extreme temperatures (ranging from subzero cold to sweltering heat)
- Condensing environments with 100% relative humidity
- Dust, salt spray, and corrosive chemicals
- Inaccessible locations requiring remote monitoring
- Hazardous zones where gas detection must be intrinsically safe
Choosing the Right Emissions Detection Technology for Harsh Environments
Selecting the right emissions detection technology is critical—especially in environments characterized by extreme temperatures, high humidity, corrosive chemicals, and limited accessibility. When evaluating technologies for use in these harsh conditions, key factors to consider include:
- Target gases
- Environmental suitability/compensation –temperature range, humidity, wind, salt, sand, and other variable conditions that might impact
- Monitoring type – continuous vs. intermittent
- Coverage – area of coverage and required proximity to potential leak sources
- Deployment – ease of installation and scalability
- Reliability – Uptime of equipment and mean time to failure
- Maintenance & operation requirements – frequency and complexity of service
- Sensitivity – minimum detection thresholds
- Quantification capabilities – ability to measure leak size and concentration

Close-Proximity Wireless Sensor Networks
Best suited for continuous, real-time monitoring in harsh environments; detects methane, hydrogen, and hydrocarbons C₁–C₁₂
Pros
- Target gases: Detects CH₄ and H₂, and hydrocarbons (C₁–C₁₂)
- Monitoring type: Continuous, real-time
- Environmental suitability: Wide operating range (–40°C to 75°C, 100% RH); corrosion, dust, and moisture resistant
- Deployment: Fast, wireless installation on existing infrastructure
- Reliability: IP65+ environmental sealing; self-testing features
- Maintenance: 15-year sensor life, 5-year battery; no required field calibration
- Quantification: Quantifies CH₄ and H₂
- Sensitivity: Detection range from 50 to 1M ppm
- Coverage: Intrinsically safe for hazardous zones—can be mounted close to leak sources to better capture intermittent leaks and low false positives
Cons
- Coverage: Localized detection; full site coverage requires strategic placement
- Deployment: Requires planning for sensor network density
Optical Gas Imaging (OGI) Cameras Using Infrared (IR) Sensor Technology
Used primarily for visual identification of hydrocarbon leaks; not suitable for hydrogen
Pros
- Target gases: Detects a wide range of hydrocarbons (C₁–C₁₂)
- Coverage: Highly directional; good for pinpointing leak locations
- Deployment: Portable for vehicle-mounted use or fixed installations available
- Monitoring type: Continuous (fixed installations)
Cons
- Target gases: Cannot detect hydrogen
- Monitoring type: Intermittent (portable installations)
- Environmental suitability: Weather-dependent; reduced effectiveness in fog, rain, or poor thermal contrast. Limited temperature range of -20°C – 50°C. Some cameras do not detect in low light or at night.
- Quantification: Standard OGI is qualitative. The camera doesn’t directly measure concentration or flow – it just shows a plume image. Operators may judge relative size by plume thickness or extent, but this is subjective.
- Reliability: Portable OGI is vulnerable to mirror corrosion, calibration drift, and environmental wear; Fixed OGI systems have better protection but still need routine servicing.
- Maintenance: Requires trained operators; subject to calibration drift
- Sensitivity: May miss small or slow leaks depending on environmental contrast
Satellite Monitoring
Scalable global coverage for large methane leaks; limited gas scope and spatial resolution
Pros
- Monitoring type: Intermittent, global-scale observations
- Deployment: No site infrastructure required
- Coverage: Ideal for identifying super-emitters or prioritizing regions for inspection
- Reliability: No site hardware, so no operator responsibility; depends on satellite health, generally high uptime but limited to scheduled passes.
- Maintenance: No end-user maintenance
Cons
- Target gases: Only detects methane; no hydrogen or VOC detection
- Sensitivity: High detection thresholds (>100 kg/h common)
- Quantification: Estimates are broad and not site-specific
- Environmental suitability: Affected by clouds, aerosols, and surface reflectivity
- Monitoring type: Not real-time; passes may be daily or weekly.
- Coverage: Poor spatial resolution; not suitable for locating leak points
Drone/UAV-Based Detection
Ideal for targeted inspections in remote or dangerous areas; limited by flight time and conditions
Pros
- Coverage: Accesses difficult or elevated areas
- Target gases: Can detect CH₄ or other gases depending on sensor payload
- Quantification: Possible with proper instrumentation and wind modeling
- Deployment: On-demand use; no permanent infrastructure
- Sensitivity: High-resolution sensors can detect small leaks at close range
Cons
- Monitoring type: Intermittent; requires scheduled flights
- Maintenance: Needs trained pilots and drone upkeep
- Environmental suitability: Wind, rain, and extreme temperatures limit usability
- Battery life/flight time: Limits area that can be covered in one flight
- Reliability: Flight time limits uptime; hardware prone to weather impacts; requires battery swaps, maintenance, and operator availability.
Mobile Ground Surveys (Vehicle-Based)
High sensitivity for methane; ideal for road-accessible inspections but limited coverage
Pros
- Target gases: Excellent methane detection
- Quantification: Real-time data with GPS and wind integration
- Sensitivity: Very high—detects small leaks with precision instruments
- Deployment: Efficient for accessible routes and recurring inspections
- Reliability: Instruments are highly reliable during surveys but uptime depends on human operation; not continuous, so “uptime” is linked to survey schedule rather than device failure.
Cons
- Accessibility: Requires accessible routes for vehicles
- Monitoring type: Intermittent and requires trained operators
- Coverage: Limited to areas with road or vehicle access
- Target gases: Typically methane only; not used for hydrogen
- Environmental suitability: Weather and terrain can affect usability
- Maintenance: Requires calibration and vehicle-mounted equipment upkeep
