Emissions & MRV
LiveNUPRC Tier-3 methane MRV — measured, not estimated.
Measurement-based MRV is becoming mandatory, and the bar is real: source-level quantification, reconciled with observation, in an audit-grade trail. PetroBrain does this today — and it’s honest about exactly what it can and can’t see.

What the deadline actually requires
From estimated to measured: the jump from Tier 2 to Tier 3.
The tiers describe how a number is produced. The shift to Tier 3 is a shift from plausible estimates to defensible measurement — and that’s where the work is.
Tier 2 — where many are
Estimated
Facility-specific factors and engineering estimates. Better than generic averages, but the headline numbers are still calculated, not observed — and an auditor can question every assumption behind them.
Tier 3 — the requirement
Measured & reconciled
Source-level quantification from direct measurement or measurement-validated calculation, reconciled against independent observation (including public satellite methane), in a trail you can hand to a regulator.
Why it’s hard
Continuous measurement
Tier 3 wants measured volumes on material sources — not once-a-year estimates. Most operators don’t yet have continuous coverage where it counts.
OGI & LDAR
Optical gas imaging plus a closed-loop leak-detection-and-repair workflow is the backbone of credible fugitive reporting. Ad-hoc fixes don’t qualify.
Metered flaring & venting
Flaring is often the single biggest reported source. If it’s estimated rather than metered, the whole inventory’s credibility wobbles.
Auditable reporting
Every reported figure has to trace back to a measurement. Spreadsheets assembled by hand are slow to produce and hard to defend.
How PetroBrain does it
LivePetroBrain builds your inventory from connected source data, reconciles it against public satellite methane, and assembles a traceable report where every figure links back to its origin. It assesses only the sources you’ve connected — unconnected facilities are reported as gaps, never assumed compliant.
The honesty box
We won’t paper over a gap to look compliant.
Calibrated honesty about data limits is the same trust asset as calibrated honesty about an engineering calculation.
“PetroBrain will tell you what it can and can’t see. It reasons over the data you have and the public data that exists — and it never invents a number to look more complete.”
If a facility isn’t connected, your report says so. A clean number you can’t defend is worse than an honest gap you can close.
