Services / Methane Data Readiness
Fixed-scope engagement that turns messy field data into a Subpart W / OOOOb / OGMP-ready inventory — field-data readiness package, evidence map and management review memo. For non-supermajor operators without a dedicated emissions platform.
From $15,000 for a single-asset applicability scope · 2–4 week inventory builds · mutual NDA before any data review.
Built for changing methane-reporting pressure
We build a current deadline and evidence map as part of the engagement, rather than relying on a static public checklist that ages fast. Satellite and aerial measurements can outpace internal inventories — we help your team be ready to reconcile source-level data when buyers or regulators ask.
Who this is for
NM Permian operator
Satellites are already publishing basin-level intensity data, and state-level pressure is building. You need the data plumbing right before the rule is in force.
Sustainability VP
Subpart W timing and applicability continue to evolve. Time to clean CY2025 source-level data, if reporting remains applicable to your facilities.
LNG developer / midstream
Under EU MR 2024/1787, importers must demonstrate and report that applicable supply contracts cover MRV-equivalent measures, with phase-in deadlines under the Methane Transparency Database. Specific timing and applicability vary by jurisdiction and supply contract.
OGMP 2.0 signatory
3-year clock on measurement-based reconciliation. Get the data architecture right before the gap analysis is your problem.
What you get
Excel workbook + PDF readiness memo + 60-minute walkthrough. One follow-up round included.
Every facility, every Subpart W source category (pneumatic controllers, dehydrators, compressors, blowdowns, tanks, flares, fugitives), with throughput + count.
What fields each emission factor calculation needs, what's missing today, where to source it.
A reproducible, auditable workbook that turns source-category inputs into reportable emissions figures aligned with the applicable rule framework. Specific equation set and references confirmed during scoping.
Typical records an auditor may request, organised for review.
Quarterly OGI cadence, advanced-monitoring alternatives under Appendix K, repair-window timing.
Executive summary, deadline calendar, gap analysis.
Why us
Stanford PhD-led. Fluent in both the rule text (Subpart W, OOOOb, OGMP 2.0, EU 2024/1787) and the data pipelines that have to feed those rules.
Our position: we hand you the measurement-to-report data architecture. Not a stack test, not a field tour.
The OOOOb Applicability Checker at tools.petropt.com runs on the same engine — you see the methodology before you commit.
How it works
20 minutes, free.
Standard turn.
SCADA exports, field tickets, GHGRP prior submissions, equipment lists.
2–4 weeks depending on facility count.
Excel workbook + PDF readiness memo + 60-min walkthrough.
One follow-up round included.
Pricing
Final scope and price depend on facility count, applicable rule scope (Subpart W, OOOOb, OGMP, EU MR, state overlays), data condition and reporting deadline. Mutual NDA before any data review.
Most first engagements are $15k–$40k readiness or diagnostic packages. Larger multi-facility data models are scoped after the first diagnostic.
Scope honesty
This is a fast, defensible decision-support package. It is not a substitute for field execution, legal advice or a signed statutory opinion.
Not a methane sensor vendor. If measurement campaigns are needed, we can help your team evaluate sensor vendors (e.g. Bridger, Project Canary, Highwood) or coordinate with your selected provider.
Not legal advice. Refer environmental counsel.
Not a registered air-permitting consultant. Trinity / Apex / Verdaen for permitting work.
FAQ
This scope focuses on the currently active reporting, monitoring and recordkeeping requirements — Subpart W reporting, OOOOb LDAR / monitoring / recordkeeping, OGMP 2.0 voluntary tiers, EU MR procurement pressure, and applicable state overlays (NM, CO, CA, TX).
Yes — NM, CO, CA and TX overlay is part of every engagement where it applies.
EU MR 2024/1787 introduces phased reporting and attestation obligations for importers of supply concluded after EU MR entry into force, with the Methane Transparency Database staged in. Specific timing and applicability vary by jurisdiction and supply contract.
