Achieving OGMP 2.0 Gold Standard
The oil and gas sector faces growing regulatory and investor pressure to reduce methane emissions. The Oil and Gas Methane Partnership (OGMP) 2.0 Reporting Framework is now the global gold standard for emissions transparency. It goes beyond high-level estimates and pushes for granular, site-specific, and measurement-based reporting.
Understanding OGMP 2.0 Reporting Levels
OGMP 2.0 defines five levels of methane emissions reporting, progressing in accuracy and granularity:
- Level 1: Asset- or country-level consolidated estimates, typically using industry averages
- Level 2: Emissions categorized by source type (e.g., venting, fugitives, flaring)
- Level 3: Reporting by detailed source using generic emissions factors (EFs)
- Level 4: Reporting by detailed source using specific EFs and activity factors (AFs) based on measurement or detailed engineering models
- Level 5: Total site-level emissions measured and reconciled with source-level estimates for a statistically representative population
The OGMP framework emphasizes continuous improvement and encourages companies to move from high-uncertainty estimates to direct measurement. The ultimate goal: reducing real emissions, not just refining estimates.
Methane Emissions Detection Technologies in OGMP Compliance
| Technology | Supports Level | Role in OGMP Framework |
|---|---|---|
| OGI (Optical Gas Imaging) | 1,2,3 | Visual leak detection; useful for early source identification |
| Handheld Detection Devices | 1,2 | Spot checks, maintenance audits |
| Drones & Mobile Ground Platforms | 3,4,5 | Mobile quantification for source and site-level scans |
| Aircraft/Aerial Surveys | 5 | Wide-area, high-level site quantification |
| Satellite Monitoring | 5 | Broad regional data, improving in resolution |
| Close-proximity Continuous Monitoring Networks | 3,4,5 | Continuous source and site-level quantification; supports reconciliation |
Roadmap: Moving from OGMP Level 1 to Level 5 Compliance
Step 1: Establish a Baseline (Level 1–2)
At this early stage, emissions are reported at the asset, venture, or country level using default emissions factors or comparisons to similar facilities.
Typical Activities:
- Review current methane inventories
- Identify core emission sources
- Use OGI or handheld devices for initial assessments
OGMP Insight: This is considered a low-accuracy, high-uncertainty method. Operators are encouraged to advance quickly to source-level identification.
Step 2: Source-Level Mapping (Level 3)
Operators begin identifying emissions by individual source types—tanks, flanges, pneumatics—using generic emissions factors (EFs).
Typical Activities:
- Conduct facility walkthroughs
- Map emissions to core OGMP categories (e.g., fugitive emissions, venting)
- Use mobile surveys or drone-based scanning
OGMP Insight: Generic EFs lack specificity, but still offer improved granularity over asset-level estimates.
Step 3: Direct Measurement at the Source (Level 4)
At this level, operators use direct measurements or engineering calculations to establish specific EFs and AFs for each source.
Typical Activities:
- Install a fixed continuous emissions monitoring system like MethaneTrack™
- Collect real-time emissions data from tanks, compressors, and valves
- Replace generic EFs with calculated factors based on operating conditions
OGMP Insight: OGMP considers direct measurement a “bottom-up” measurement method. This type of measurement signals high confidence in emissions accuracy.
Step 4: Site-Level Reconciliation (Level 5)
The final level requires operators to conduct site-level quantification and reconcile it against source-level estimates.
Typical Activities:
Use continuous monitoring technology across statistically representative sites
Supplement with satellite or aerial surveys when appropriate
Analyze total site emissions and compare against summed source-level data
OGMP Insight: Level 5 reporting validates your entire emissions profile and is the strongest demonstration of actual emissions performance.
Why Continuous Methane Monitoring Matters for OGMP 2.0
While OGI, drones, and satellites offer valuable periodic insights, only fixed, continuous monitoring systems meet OGMP’s call for sustained, representative, real-time measurement.
Key benefits include:
- Real-time detection and response – Identify and address leaks immediately to minimize environmental impact and avoid penalties.
- Improved accuracy and reliability – Deliver consistent, measurement-based data for precise OGMP 2.0 reporting.
- Enhanced LDAR support – Provide ongoing surveillance that strengthens leak detection and repair programs.
- Super emitter event capture – Detect sudden, large-scale emissions that intermittent inspections might miss.
- Transparency and accountability – Enable granular, verifiable reporting for regulators and stakeholders.
In short, continuous monitoring equips companies to comply with evolving methane regulations, improve operational efficiency, and demonstrate their commitment to environmental stewardship.
Not All Continuous Monitoring Technologies Are Equal for OGMP 2.0
Why the Technology Choice Matters
OGMP 2.0 Levels 3, 4, and 5 require progressively higher accuracy, granularity, and defensibility in emissions data. While multiple technologies fall under the umbrella of “continuous monitoring,” their capabilities vary widely. Some may detect methane but fail to quantify it precisely, assign activity factors, or support site-level reconciliation—all essential for Level 4/5 reporting.
Below, we compare three commonly considered options for continuous monitoring—fenceline laser-based spectroscopy, fixed OGI (IR) cameras, and MethaneTrack™ Close-Proximity Wireless Sensor Networks—in terms of OGMP 2.0 compliance needs.
Fenceline Laser-Based Spectroscopy
Provides perimeter-based detection by sending a laser beam across a fixed path to measure methane concentrations.
- Pros: Good for detecting large plumes and super-emitter events, minimal on-site footprint.
- Cons: Limited ability to pinpoint exact sources or measure emission rates; quantification often relies on modeling; poor at capturing intermittent leaks from small components, narrow environmental operating range due to heat and cold sensitivities, requires human verification of leak events.
OGMP Fit – Can support Level 3 for detection; limited value for Level 4/5 because it lacks source-level quantification.
Fixed OGI (Infrared) Cameras
Uses thermal imaging to visually detect methane leaks in real time.
- Pros: Clear visual confirmation of leaks, useful for identifying leak locations during inspections.
- Cons: Camera performance declines in poor weather or low optical contrast; quantification can require separate tools, requires regular maintenance by trained technicians.
OGMP Fit – Useful for Level 3 identification; partial support for Level 4 when paired with quantification tools; not practical for Level 5 continuous reconciliation.
MethaneTrack™ Close-Proximity Wireless Sensor Networks
Intrinsically safe wireless sensor devices placed on or near likely leak sources to continuously measure methane concentration and leak rate.
- Pros: True 24/7 unattended operation, source-level detection, real-time quantification, automated EF/AF calculation, integrated data for Level 4 and 5 reporting, minimal maintenance.
- Cons: Requires deployment planning for sensor placement (but easy to scale).
OGMP Fit – Purpose-built for Level 4 and Level 5 compliance, including site-level reconciliation.

FAQs on OGMP 2.0 Compliance
What’s the difference between OGMP Level 4 and Level 5?
Level 4 focuses on source-specific measurement using detailed EFs and AFs. Level 5 adds site-wide measurement and reconciliation between bottom-up and top-down data.
How often do I need to conduct site-level measurement for Level 5?
OGMP recommends a risk-based approach. High-emitting or high-discrepancy sites may need more frequent measurement. MethaneTrack™ enables continuous coverage to reduce the need for periodic campaigns.
Is satellite data enough for Level 5 reporting?
Not typically. Satellites can support site-level estimates, but must be complemented by on-the-ground sensors or mobile surveys to meet OGMP’s statistical and methodological rigor.
Can I achieve Gold Standard without deploying sensors on all sites?
Yes. You must report at Level 4 or 5 for all material assets, which collectively represent 95% of your total methane emissions. MethaneTrack™ makes this scalable by offering cost-effective, continuous coverage with our wireless sensor devices that can be mounted with a magnetic clamp or with stainless steel cable ties for easy positioning and repositioning.
However, if you are trying to reduce emissions, Close-Proximity Continuous Monitoring provides the fastest way to reduce emissions. The combination of immediate detection with automated leak alerts to the repair team, can enable up to 99% lower emissions compared to quarterly monitoring.
What are the timelines for achieving Gold Standard?
OGMP 2.0 allows up to 3 years for operated ventures and 5 years for non-operated ventures to reach Level 4/5. MethaneTrack™ helps meet this timeline with minimal manual effort.
