What Is TetraSoft? Emissions Reporting Built by Scientists

TetraSoft is a software and data company that automates methane and greenhouse gas emissions reporting for oil and gas operators across US jurisdictions. The company is a spinout from Colorado State University. Its founders, Arthur Santos, Ph.D. and Jerry Duggan, Ph.D., were research scientists from METEC, the Methane Emissions Technology Evaluation Center at CSU and the world’s leading methane detection technology evaluation facility . This post explains what TetraSoft builds, who it serves, and why the founding context matters for how the software works.

What TetraSoft Builds

TetraSoft’s product line centers on an emissions reporting SaaS for O&G operators, supported by a publicly accessible data dashboard and planned MAES-based estimation and Measurement-Informed Inventory products. The reporting software is the core commercial product today.

The Emissions Reporting SaaS Converts Operational Data Into Compliant Reports

TetraSoft’s reporting SaaS converts structured operational input data into compliant, jurisdiction-specific emissions reports. Active support covers Colorado’s ONGAEIR program, administered by CDPHE, which requires annual air emissions reporting from oil, gas, and midstream operators in Colorado. GHGRP Subpart W, which covers petroleum and natural gas systems at facilities reporting more than 25,000 metric tons CO2e annually, is also in active development on TetraSoft’s roadmap. EPA has proposed suspending mandatory Subpart W reporting obligations for nine of ten O&G segments through reporting year 2034 [1] and extended the 2025 reporting deadline to October 30, 2026 [2]. Despite that regulatory pause, a number of operators are planning to continue Subpart W reporting on a voluntary basis to satisfy investor and stakeholder expectations around emissions transparency. TetraSoft’s Subpart W module is built to serve that voluntary reporting use case. The roadmap extends to all US states.

The process the software replaces is familiar to most compliance teams: manually reconciling equipment inventories against regulatory emission factor tables, then reformatting output for agency submission. For a team managing dozens of facilities, that process can consume several weeks each reporting cycle. The software generates jurisdiction-specific report outputs directly from structured operational inputs. Those inputs include equipment inventories, throughput records, and gas composition values.

The Atlas Dashboard Provides Structured Public O&G Data for Colorado and Texas

The Atlas Dashboard is a publicly accessible interactive map of Colorado and Texas O&G facility, production, and emissions data, currently available at no cost. [3] The Colorado dataset covers more than 168,000 wells, 59,000 facilities, and 460,000 equipment rows across 48 counties, drawing on four-plus years of ONGAEIR data. Texas coverage extends to more than 1.1 million wells.

Monthly production records from the Railroad Commission of Texas (RRC) total more than 339 million entries. New Mexico is the next state planned for inclusion, with the goal of covering all US states. The Atlas gives analysts, consultants, and operators access to structured public data without building the scrape-and-clean pipeline themselves.

The Science Behind the Software

TetraSoft’s founders are the researchers who built MAES and coordinated and designed field measurement campaigns to identify emissions from upset conditions, sources often missing from standard inventories. That is not a marketing credential. The founding context directly explains why the software models physical processes rather than looking up regulatory emission factors.

Jerry Duggan, Ph.D. was the lead developer of MAES at CSU. Arthur Santos, Ph.D. led MAES application work directly with operators including Chevron, EQT, Occidental, Civitas, CNX, Seneca, and MPLX through CSU’s Energy Institute. Both hold Systems Engineering doctorates from CSU. MAES was developed jointly at CSU and UT Austin through the Energy Emissions Modeling and Data Lab (EEMDL), a $50 million industry-academic initiative. TetraSoft uses MAES through a partnership and license agreement with CSU.

Standard emission factor methods multiply equipment counts by a regulatory lookup table value drawn from population-average data. MAES models the physical processes governing emissions at each facility: fluid flow, equipment operating states, gas composition by separation stage, and failure mode probabilities [4]. MAES does not produce a single calculated value. The output is a probability distribution of expected emissions at one-second temporal resolution.

Peer-reviewed research has found that bottom-up, factor-based inventories underestimate actual facility methane emissions by at least a factor of two [5] [6] [7]. This finding applies to the facility types and geographies studied in those field campaigns and may not generalize universally without additional study. For an operator with a public methane intensity commitment, a factor-of-two gap between reported and actual emissions is not a rounding error. For operators with public commitments, that gap is a credibility problem.

Two products are planned on the MAES foundation. MAES-based emissions estimation generates physics-based, facility-specific emission ranges from operator inventory and operational data. Measurement-Informed Inventories (MII) integrate MAES simulation with field measurement data to quantify both routine and abnormal process emissions. MII is the technical pathway to OGMP 2.0 Level 4/5 reporting and to methane intensity accounting that satisfies investor and European buyer scrutiny. [8]

Who TetraSoft Serves

TetraSoft’s reporting SaaS is built for compliance professionals and operations engineers who manage state and federal emissions reporting workflows, and for sustainability leaders who need a credible methodology for voluntary programs like OGMP 2.0 and investor-facing methane reporting. The platform supports Colorado ONGAEIR today and is designed to extend to every US state that requires emissions submissions, plus federal programs like GHGRP Subpart W and international frameworks.

Compliance and environmental professionals are the primary users of the reporting SaaS. These are the engineers and managers who build the annual emissions data file their company submits to CDPHE or EPA. The software reduces manual reconciliation. It produces a documented, reproducible calculation trail for audit purposes.

Production engineers and field data managers provide the operational data those submissions depend on. Equipment status changes, mid-year throughput shifts, and gas composition updates are where calculation errors typically enter the process. Structured data intake reduces late-cycle reconciliation work.

Sustainability and ESG leaders at operators with OGMP 2.0 obligations or public methane intensity targets need methodology credibility that factor-based inventories cannot provide. MII and MAES-based estimation address that gap directly.

TetraSoft is a software company. The products are built to scale and to deliver repeatable, defensible results across operators and jurisdictions without requiring custom engagements for each reporting cycle.

Frequently Asked Questions

What jurisdictions does TetraSoft currently support?

TetraSoft actively supports Colorado ONGAEIR as of February 2026. GHGRP Subpart W is in active development. The product roadmap covers all US states. MAES-based estimation and MII services extend to international operators subject to OGMP 2.0 and EU CSRD frameworks. Coverage status changes as the development roadmap progresses.

Does MAES-Based Estimation Require Operators to Deploy New Field Measurement Equipment?

No. MAES-based estimation draws on operational data operators already maintain: equipment inventories, throughput records, gas composition values, and operating state data. No new sensors or field measurement programs are required for MAES-based estimation. Measurement-Informed Inventories (MII) do integrate field measurement data, but MAES-based estimation is a simulation workflow that runs from existing structured operational records. TetraSoft uses MAES through a partnership and license agreement with CSU.

Is TetraSoft a consulting firm?

TetraSoft is a software company focused on delivering products that help operators solve critical emissions reporting problems. Both founders hold Systems Engineering Ph.D.s from CSU and worked directly with O&G operators on facility-level emissions through CSU research programs before founding the company. The products are designed to scale across operators and jurisdictions. Where operators need regulatory or compliance guidance specific to their operations, that requires qualified counsel.

What does the Atlas Dashboard cover, and how is it different from downloading public O&G data directly?

The Atlas Dashboard provides structured, map-based access to Colorado and Texas O&G data, including more than 168,000 Colorado wells and more than 1.1 million Texas wells, linked across equipment, production, and emissions fields. Raw public data from COGCC, CDPHE, and the Texas RRC requires substantial cleaning before it supports analysis. TetraSoft processes and structures those datasets on an ongoing basis. The Atlas makes the result accessible without requiring the analyst to build or maintain the underlying pipeline.
