Argentine oil & gas open data from the Secretaría de Energía CKAN portal: well-level Capítulo IV production metadata (85,380 wells), unconventional shale/tight monthly production (400,759 rows, 2006-present), master well registry (84,242 wells), Vaca Muerta directional well trajectories (2,133 wells), and per-job fracture detail (4,696 jobs). First CKAN datastore connector in PatchOps. HTTP only — host has broken HTTPS. Filters are strict case-sensitive — use enumValues from getServiceInfo.

British Columbia Energy Regulator — oil & gas well data for BC (Montney play, WCSB). Public ArcGIS REST, no auth. METHODS: searchBCWells, getBCWellDetail, searchAllInternationalWells CRITICAL USAGE RULES: 1. Well IDs are BC-specific authority numbers (not US API format) 2. Use field or formation for play names like Montney; in BC this primarily matches well-area/play labels and sometimes well names 3. searchAllInternationalWells is a cross-jurisdiction sweep (currently BC only; expands as more jurisdictions wire in) 4. bbox params are [minLon, minLat, maxLon, maxLat]

CENACE (Centro Nacional de Control de Energía) — Mexico's grid operator / ISO. The canonical Mexican wholesale-power PML feed (Precios Marginales Locales / Locational Marginal Prices). Public PÚBLICA web service, no key. Hourly LMP per node for day-ahead (MDA) and real-time (MTR) markets, with energy/loss/congestion components. Systems: SIN (national grid), BCA (Baja California), BCS (Baja California Sur). upstream quirks: non-standard port 8082; hard 7-day date-range cap per request (getNodePriceSeries chunks longer histories); node keys are system-specific (a SIN key under BCA returns ZERO_RESULTS); no node-catalog endpoint; Spanish field names; price strings parsed to numbers.

Colombian oil & gas open data published by ANH (Agencia Nacional de Hidrocarburos) via datos.gov.co Socrata SODA. First Socrata connector in PatchOps. Datasets (live-probed 2026-05-07): - Crude oil production (51,924 monthly rows) ⭐ field/operator/department/contract + Point geometry - Gas production (69,074 monthly rows) ⭐ same shape, gas in KPC - Active contracts (275) ⭐ operator/cuenca/estado/etapa - Production tests (723, 2025-2026) initial + extended well tests - Field royalty liquidations (203,572) USD price, COP regalías per field-month upstream quirks: SoQL filters case-sensitive (CASANARE not casanare). Numbers stored as text with mixed US (11,955.00) and EU (63,13) formats. Year column on royalties is "a_o" (mangled "año").

Pan-EU harmonized offshore oil & gas — OGC WFS 2.0.0, no auth. 18 EU countries (Croatia, Cyprus, Denmark, Faroe Islands, France, Germany, Greece, Ireland, Italy, Latvia, Malta, Montenegro, Netherlands, Norway, Poland, Portugal, Spain, UK). Annual refresh — breadth filler; prefer sodir/nsta for authoritative national data. Layers: - hydrocarbons (~28.5K wells) ⭐ status/purpose/content/country filters - platforms (~1.6K) ⭐ currentStatus/category/primaryProduction - pipelines (~3.9K) ⭐ medium/status/country - activelicenses (~1.3K polygons) type/country

Australian Commonwealth offshore petroleum wells and seismic surveys (NOPTA / NOPSEMA). Find wells in Carnarvon/Browse/Bonaparte/Otway/Gippsland basins, search 2D and 3D seismic survey footprints. Production volumes not included — permanently confidential under Australian Regulations 8.02(3)/10.02(3). CC-BY 4.0.

New Zealand petroleum permits, wells, and geophysical surveys from NZ Petroleum & Minerals (MBIE). Covers active prospecting, exploration, and mining permits — primarily Taranaki Basin. 1,267 wells and 38 active permits. Production volumes are published separately by MBIE (PDF/Excel); this connector covers spatial and regulatory data only.

Geological Survey of Queensland — ~190k datasets: well completion reports (16k+), well proposals, hydraulic-fracturing reports, petroleum production/reserves reports, boreholes, seismic, geochemistry, magnetic/radiometric/gravity grids. No-auth CKAN 3. METHODS: packageSearch, packageShow, resourceShow, searchPetroleumReports, searchBoreholes, listOrganizations, listGroups, getServiceInfo RULES: 1. Vocab values are full URIs (linked.data.gov.au/def/...); fq accepts `:*petroleum` shorthand. 2. Single org (GSQ), single group (geoscience). 3. Pagination caps at 1000 rows; use `start`. 4. `type`: report | borehole | map-collection | geochemistry | seismic | magnetic | radiometric | electromagnetic | gravity | dataset | gravity-gradiometry | spectral | magnetotelluric | electrical.

Queensland Open Data Portal — 188k+ QLD government datasets. Strong O&G: petroleum/gas production stats, CSG/condensate/crude/LPG/natural-gas reserves, tenure, environment. CKAN 3 with search, package/resource metadata, and datastore queries incl. SELECT-only SQL. Platform JWT embedded for higher rate limits. METHODS: packageSearch, packageShow, resourceShow, datastoreSearch, datastoreSearchSql, listOrganizations, listGroups, getServiceInfo RULES: 1. `datastore_active: true` ≠ parsed rows; XLSX often empty — fall back to download URL. 2. Pagination caps at 1000 rows; use `start` / `offset`. 3. datastoreSearchSql rejects non-SELECT.

Norwegian Continental Shelf (NCS) open data — 9,765 wellbores, 142 fields, 645 discoveries, 1,809 licences, 82 pipelines, 1,215 facilities, 5,008 seismic surveys. - searchWellbores ⭐ operator/status/purpose/content/field/area/date - getWellbore ⭐ by name (e.g. '33/12-1') or NPDID - searchFields ⭐ Producing/Approved for production/Shut down - searchDiscoveries ⭐ status, HC type, operator, year range - searchLicences ACTIVE/INACTIVE polygons - searchPipelines medium (OIL/GAS), phase, facility - searchFacilities platforms, FPSOs, subsea — kind/phase - searchSeismicSurveys 2D/3D/4D acquisition areas - getWellboreFormationTops lithostratigraphy per wellbore - getWellboreDST drill stem tests per wellbore - getFieldReserves oil/gas/NGL/condensate reserves (multi-vintage)
