Built by scientists.
Grounded in real data.
TetraSoft is an emissions software company that builds Atlas, a map of public oil and gas regulatory data, and MAES, a methane emissions simulator, for operators, consultants, researchers and analysts.
TetraSoft turns methane simulation science and regulatory data intelligence into operator-grade tools, so the industry can measure what it actually emits with confidence.
The platform that gives the oil and gas industry full visibility into emissions: their own and the industry's.
TetraSoft LLC is a Colorado State University spin-off in Fort Collins, Colorado. We spent years applying MAES to real O&G sites and defending the numbers with regulators. No reporting tool brought that science to compliance work, so we built one.
What TetraSoft does
Atlas
Public oil and gas regulatory data on one map: wells, facilities, production, inspections and emissions. 8 states, 2,625,482 records, refreshed monthly.
MAES Platform
Our platform for the MAES engine from CSU and UT Austin: guided equipment setup, automated Monte Carlo runs and interactive results. It simulates methane emissions equipment by equipment, including failures, and reports them as probability distributions instead of emission-factor averages.
Independent emissions estimates
Facility-level methane estimates from MAES, using its peer-reviewed methodology, for operators and consultants who need an independent number alongside a reported inventory.
Free calculators
Seven free tools for compressor engines, glycol dehydrators, heating value by state and gas unit conversions.
What makes TetraSoft different

Published MAES results: 1.16× ONGAEIR-reported methane in the DJ Basin (Santos et al., ACS ES&T Air, 2025), 1.47× statewide in Colorado on 2024 ONGAEIR data (COBE updated final report, November 2025) and 1.64× for Appalachian midstream sites (AMI 2024 campaign).
Who uses TetraSoft
- Compliance and land teams at small and mid-size operators
- Landmen and title and abstract firms checking well status, operator and production
- Environmental due-diligence firms screening sites for orphan wells, spills and enforcement
- Saltwater disposal operators reviewing nearby injection wells
- Mineral and royalty owners checking whether their wells produce, who operates them, and spills or violations nearby
- Oilfield service companies finding where permits and drilling activity are
- Gas midstream planners reviewing gas plants, pipelines and gas composition by area
- Regulators and researchers comparing inspections, enforcement and emissions across states
- Emissions consultants running MAES studies for several operators
- Energy investors and analysts
- ESG and sustainability teams that need independent emissions estimates
- University researchers, on the Academic MAES license
The team behind TetraSoft
Both founders are systems engineers from CSU's Energy Institute who developed and applied MAES at METEC. They started TetraSoft because operators were spending weeks on reports that better tools could produce in hours.
Jerry Duggan, Ph.D.
Jerry spent years as a senior software architect at HP, building large-scale IT management systems where reliability wasn't optional. That's the discipline he brought to MAES: versioned, testable, deployable code that holds up when different teams run it in different places.
He also built data infrastructure for METEC, handling real experiment streams under real operational demands. A fragile workflow doesn't just slow things down. It makes the results questionable.
Jerry holds a Ph.D. in Systems Engineering from CSU, an M.S. in Computer Science from University of Utah, and a B.S. in Math and Computer Science from New Mexico State University.
Arthur Santos, Ph.D.
Arthur spent years at the CSU Energy Institute as a Research Scientist, translating real facility data into defensible emissions estimates. He led the applied side of MAES, driving how the tool gets used at the facility level with actual equipment detail, not just how sites are configured on paper.
He has worked directly with Chevron, EQT, Occidental, Civitas, CNX, Seneca, and MPLX. That work covered upstream and midstream configurations across the equipment types and edge cases that keep reporting teams up at night.
Before CSU, Arthur was at Pacific Northwest National Laboratory on power systems and applied infrastructure. Tools need to work in imperfect conditions. He learned that early. He holds a B.S. in Electrical Engineering from CEFET-MG (Brazil), an M.S. in Electrical & Computer Engineering, and a Ph.D. in Systems Engineering from CSU.

Frequently asked questions
Does Atlas use proprietary operator data?
No. Every Atlas record comes from a public state or federal regulatory filing.
How much does TetraSoft cost?
Atlas costs $99–$499 per month. MAES is priced per user per month: $769–$1,149 per user per month (Professional) or $499–$749 per user per month (Academic). Both start with a 7-day free trial.
What is MAES?
MAES, the Mechanistic Air Emissions Simulator, is a methane emissions engine developed at CSU's METEC facility and the CSU and UT Austin Energy Emissions Modeling and Data Lab, with a peer-reviewed methodology. It models each piece of equipment at a facility, including failures, and returns emissions as a probability distribution. TetraSoft's founders helped build and apply the engine at METEC, then built the MAES Platform around it: Project Manager, Studio and Results replace hand-prepared engine inputs with guided equipment setup, automated Monte Carlo runs and 35 interactive result plots, so studies are faster to set up and reproducible.
Which states does Atlas cover?
Atlas covers 8 states: Colorado, New Mexico, Ohio, Oklahoma, Pennsylvania, Texas, West Virginia and Wyoming.
Is TetraSoft part of Colorado State University?
TetraSoft is a CSU spin-off, built on research from CSU's Energy Institute and the METEC methane facility.
The science is in the software.
Years of emissions modeling, deep O&G process knowledge, and direct engagement with operators and real operational data shaped every part of Atlas. The research is already done. Now it works for you.
