Same lens, different regimes
- The measure. Flared+vented gas divided by gas-equivalent production (gas + liquids at energy equivalence), summed over a 12-month window — a unitless ratio computed identically on both sides (Alberta volumes converted at 1 e3m³ = 35.3147 MCF). A unit needs ≥2,000 MCF flared+vented and real production in the window to be ranked; dot size is flared+vented volume.
- The units. Alberta reports against facilities (batteries, plants); Texas against leases. Both are the operator’s reporting unit above the well — neither jurisdiction publishes complete well-level attribution, so this is as close as public data gets.
- The windows align exactly. The slider steps through every 12-month window both public archives share. Alberta’s archive is a rolling ~5 years; Texas publishes back to 1993 but its two newest months are still filling in.
- Transparency differs. Alberta publishes vented and flared volumes separately for every facility. Texas operators have reported the split since 2021, but every bulk product the RRC publishes folds it back into one “vented or flared” number — so the combined series is what both maps show.
- Not a scoreboard. Different rules, different measurement, and both jurisdictions under-report against satellite observation. Absolute levels aren’t comparable; the ratio, the outlier structure, and the trends are.
Data: Petrinex (Alberta, refreshed weekly) and the Railroad Commission of Texas PDQ dump plus public GIS well locations (monthly). Alberta facility locations are DLS centroids (median ~270 m); Texas leases sit at the median surface location of their wells.
