Are you ready for MiQ?
How does your Facility Stack up?
Curious what you can change to get a better grade?
MiQ invites new Natural Gas Producers and Operators to assess their emissions intensity score for the purposes of pursuing certification. This tool was developed with the support of Highwood Emissions to evaluate an Operator’s portfolio of emission sources as they apply to the MiQ Standard.
The value of this tool is to allow Operators a quick check of their initial calculated Methane Intensity and MiQ Grade while moving through the MiQ Standard for Methane Performance.
Different Oil and Gas reservoirs, Regulatory Jurisdiction and Equipment Choice, greatly impact your Methane Intensity and potential for emission reductions.

Case Study: Alberta Conventional Oil Facility
- GOR = 0.69
- Emissions = 256 tons CH4
- MI = 0.15
- MiQ C grade for Intensity
Alberta Regulatory Requirements:
- Fugitive leak detection and repair program (LDAR). Depending on the facility type, Directive 060 requires a minimum of annual OGI surveys up to 3x per year
- Beginning 2023 pneumatic devices need to be limited to a vent rate of 0.17m3/hr
- Beginning 2022 existing reciprocating compressor fleet average venting is limited to 0.35m3/hr/throw
- Where any single compressor venting needs to be below 5.0 m3/hr/throw
- Beginning 2022 existing centrifugal compressor venting needs to me below 10.2 m3/hr/compressor
- Compressor seal testing is required at least every 9000 hours that it is pressurized
- Total overall gas venting is limited to 15.0 103m3 of vent gas per month or 9.0 103 kg of methane per month.
- Allowable Methodology for GHG Emissions calculations AB GHG Quantification Methodologies
Case Study: US Eastern Marcellus Gas Facility
- Emissions = 109 tons CH4
- GOR = 1.0 tons
- MI = 1.1%
- MiQ Grade B for intensity
Local Configuration includes:
- Limiting pneumatic device venting
- Measuring compressor seal vents
- Completing required fugitive emission monitoring
- No sources from flaring or storage tanks
- Primary opportunity for reduction for electrification of combustion
Case Study: Low leak configuration
- Emissions = 72 tons CH4
- GOR = 1.0
- MI = 0.07%
- MiQ B Grade for Intensity
Local configuration:
- Pneumatics that are electrified or converted to instrument air
- Tank vented is connected to a VRU or tied into a flare or sales gas line
- Heavy or conventional oil facilities may have higher intensities due to more associated gas venting and tank venting activities where low intensity producers are more likely to be pure gas plays
Case Study: Permian Oil and Gas Facility
- Emissions = 228 tons
- GOR = 0.1
- MI = 0.35
- MiQ D Grade for Intensity
Local Configuration includes:
- High bleed pneumatics
- No tank controls, not yet connected to VRUs
- Population counts for leaks, instead of individual leaks
- Associated gas well production leads to flaring
