Known Limitations and Assumptions

LGN is NGL, not LNG

"LGN" on this dashboard is ANP's own label, Líquido de Gás Natural — natural gas liquids (LPG plus C5+ condensate-like liquids stripped out at processing plants) — the inverse concept from GNL (Gás Natural Liquefeito, liquefied natural gas / LNG). Checked directly against ANP's own metadata document for this exact file and against the raw CSV's own PRODUTO column, both of which read LGN, not GNL — this is ANP's own terminology, not a translation choice made here.

Imports: one national total, no origin split

The imports file gives a single national monthly import total; it does not split Bolivia-sourced pipeline imports from LNG. That total is what's shown here — an origin breakdown is not invented from other sources. If ANP's imports file isn't reachable when the dashboard rebuilds, an explicit "import data unavailable" notice is shown instead of silently charting a zero.

Publication lag

ANP typically publishes with roughly 2 months of lag.

The balance identity is a check, not a guarantee

Available ≈ Production − Flare/loss − Own use − Reinjection is a useful sanity check on this data (it reconciles to within a fraction of a percent in practice), but each series is independently published by ANP rather than derived by summing the others — small month-to-month discrepancies between the identity and the published Available figure reflect ANP's own data, not an error in this pipeline's arithmetic.
