Catalytic Methane Abatement System
Designed to Reduce Methane Emissions from Natural Gas or Oil Wellheads
Up to 99.7% Methane Destruction. 85%+ GHG Reduction. Proven in the Field!
In 2019, ETTER Engineering invented and patented the Catalytic Methane Abatement System (CMAS) a field-proven solution designed to actively destroy fugitive methane emissions at the source. Protected under U.S. Patent #10,150,081 with corresponding Canadian patent protection, CMAS was engineered specifically for upstream oil and gas operators seeking practical, reliable methane mitigation.
The CMAS converts methane into CO₂ and water vapor using a platinum-based catalyst without requiring external electrical power. The system is CSA/FM approved for Class I, Division I hazardous locations and built for continuous outdoor operation.

Independently Field-Tested by Saskatchewan Research Council
In Spring 2024, field trials conducted by the Saskatchewan Research Council (SRC) demonstrated methane destruction efficiency of up to 99.7% under real-world operating conditions.
At sites with leaner gas streams, CMAS consistently achieved approximately 95% destruction efficiency, translating to 85–90%+ reduction in overall greenhouse gas impact.
The results confirmed that CMAS performs on par with traditional combustors — while offering lower equipment complexity, easier installation, and reduced overall cost.

Measurable Performance. Practical Deployment.
The Catalytic Methane Abatement System (CMAS) actively destroys methane at the source.
Using a platinum-based catalytic oxidation process, CMAS converts methane into CO₂ and water vapor — without external electrical power and without open flame combustion. By eliminating methane emissions at the wellhead, CMAS reduces environmental impact while supporting operational stability and production efficiency.

Minimize Methane Emissions, Maximize Efficiency
Methane is one of the most potent greenhouse gases — with a Global Warming Potential more than 70x greater than CO₂ over a 20-year period. During normal oil and gas operations, methane is frequently vented through:
Surface casing vents, Pneumatic control systems and Low-flow wellhead emissions.
These vent streams contribute to regulatory risk, carbon liability, and unnecessary atmospheric release.

Surface Casing Vent Capture
CMAS addresses the major source of methane emissions from surface casing vents by capturing and mitigating gas buildup, preventing leaks and reducing atmospheric methane.
Pneumatic Control Conversion
CMAS works seamlessly with pneumatic controls to convert methane into CO₂ and water vapor, further reducing environmental impact while enhancing production efficiency.
Enhanced Oil Production
Beyond just mitigating methane emissions, CMAS contributes to the overall efficiency of oil production, improving overall operational performance and profitability.
