Every feature is classified by activity: crude oil refinery, bitumen/lubricants, petrochemical, mineral/chemical, biorefinery, field/gas processing, storage/terminal or other. Only crude oil refineries feed refinery counts, maps and capacity; type=all lists the rest.","Classification evidence is explicit: confirmed (manual review with a public source, EIA record or Wikidata oil-refinery class), capacity-tag (OSM refinery name with barrels-per-day capacity) or osm-tag (OSM tags only). Changes are recorded in validationHistory; records leaving an edition remain in the retired list with the reason. Status is operating/idle (EIA), closed (Wikidata or OSM end tags), planned (OSM construction tags) or unknown.","Capacity is never estimated. US values are EIA Refinery Capacity Report 2026 atmospheric crude distillation capacity as of January 1, 2026 (barrels per calendar day unless a field says stream day). Elsewhere, a capacity appears only where an OpenStreetMap contributor tagged it, and it remains an unverified tag.","EIA records join an OSM site only when company and place names agree or a single named site lies near the EIA town; otherwise the EIA record is listed without coordinates. The town point is used only for matching.","Country counts are mapped sites, not capacity or throughput. Country assignment uses Natural Earth 1:50m outlines, with a nearest-outline fallback within 30 km for coastal sites.","Chokepoint flows are EIA estimates of crude oil and petroleum liquids in million barrels per day; corridors drawn between them are schematic, not vessel tracks. 2025-H1 is the first half of 2025; Panama Canal values are fiscal years."],"_wellficent":{"edition":"2026-10-31-r2","sha256":"b0bc066795eb062d3a6df33530257e289b3e762d6555b4ff63100f62d859f998","generatedAt":"2026-10-31T02:15:16Z","sources":[{"id":"osm","name":"OpenStreetMap contributors · Overpass API export","url":"https://www.openstreetmap.org/copyright","license":"ODbL-1.0","licenseUrl":"https://opendatacommons.org/licenses/odbl/1-0/","snapshot":"2026-10-31T01:20:01Z","sha256":"beffdc4b0ab15ac49a9207b3712ba868c280bcfd4a580cefd6aae7aa53ab6088"},{"id":"wikidata","name":"Wikidata","url":"https://www.wikidata.org/wiki/Q12353044","license":"CC0-1.0","licenseUrl":"https://creativecommons.org/publicdomain/zero/1.0/","snapshot":"2026-10-31","sha256":"07b152fb890c1c98d561e5626c649ec4e984a39770bb89ff3a3fff0d01bfb67a"},{"id":"eia-refcap","name":"U.S. EIA · Refinery Capacity Report 2026 (capacity as of January 1, 2026)","url":"https://www.eia.gov/petroleum/refinerycapacity/","license":"US-Government-Public-Domain","licenseUrl":"https://www.eia.gov/about/copyrights_reuse.php","snapshot":"2026-01-01","sha256":"5b3c06f37b2924a6924e7643cc7ad529ebdb85fd6049e780f5883f88dfb17eb4"},{"id":"eia-chokepoints","name":"U.S. EIA · World Oil Transit Chokepoints, Table 1 (last updated March 3, 2026)","url":"https://www.eia.gov/international/analysis/special-topics/World_Oil_Transit_Chokepoints","license":"US-Government-Public-Domain","licenseUrl":"https://www.eia.gov/about/copyrights_reuse.php","snapshot":"2026-03-03","sha256":null},{"id":"natural-earth","name":"Natural Earth · Admin 0 countries 1:50m and land 1:110m","url":"https://www.naturalearthdata.com/","license":"Public-Domain","licenseUrl":"https://www.naturalearthdata.com/about/terms-of-use/","snapshot":"5.1","sha256":"3e458fc036ad0a66411f2c1e6cac49c5d7bfb81cb1123bc513b22511a2b7fdeb"}]}}
