California State Lands Commission (CSLC) — state's coastal tidelands and submerged O&G leases. AGOL services3.arcgis.com/5aaQCuq3e4GRvkFG owned by CA_State_Lands_Commission (probed 2026-05-02). 5 services exposed via 5 methods: searchOffshoreLeases (~34 polygons — Active 26 / Inactive 8) ⭐ covering Long Beach Unit and Wilmington field tracts; searchOnshoreLeases (~5.5K CSLC leases) ⭐ defaults to TypeofLease='Oil & Gas Lease' (76 records); searchSchoolLands (~1.3K PLSS polygons keyed by TWP/RNGE/SEC_TRCT/MERID — note CNTY field 4-char NOT COUNTY); searchGrantedLands (~115 tidelands grants to coastal cities, Active 105 / Repealed 4); getServiceInfo. **upstream quirks**: Offshore_Lease_Polygons schema is lean — only PRC (lease number string) + Lease_Stat + Notes + shape; no lessee/operator/dates. CSLC Leases dates are ISO 8601 timestamp strings; Latitude/Longitude also stored as STRING fields with geometry.x/y as fallback. School_Lands uses `CNTY` not COUNTY; handler fixes single 'Tinity' typo to Trinity. Granted_Lands COUNTY has both 'Marin' + 'Marin County' variants — handler matches both via UPPER LIKE pattern. CSLC Leases TypeofLease has 27 distinct values; LeaseorPermit has 4 (General Lease/Mineral Resource Lease/Permit/Other Authorized Use); RecordStatus is degenerate (all 5524 = Active).

California SWRCB + DWR water connector — multi-host (probed 2026-05-02). SWRCB native at gispublic.waterboards.ca.gov (Drinking Water + StreamGages); DWR utility map at utility.arcgis.com (Bulletin 118 Groundwater Basins). 3 services via 4 methods: searchDrinkingWaterSystems (~4,991 SABL Drinking Water System Area polygons; BOUNDARY_TYPE Water Service Area=4963/Jurisdictional=28; FEDERAL_CLASSIFICATION COMMUNITY=2786/TRANSIENT NON-COMMUNITY=1275/NON-TRANSIENT NON-COMMUNITY=849/NON-PUBLIC=81; OWNER_TYPE_CODE P/L/F/S/M with trailing space; ACTIVITY_STATUS_CD always 'A '; COUNTY UPPERCASE) ⭐; searchGroundwaterBasins (~515 DWR Bulletin 118 basin + subbasin polygons; Region_Office SRO 227/NRO 129/NCRO 82/SCRO 77; NO county column on layer — handler surfaces this in notes) ⭐; searchStreamGages (~2,597 gages from USGS=2078, DWR=181, OTHER=124, PG&E=25, USACE=20, USBR=20, CDFW=others; gage_status Active-High Quality/Active-Limited Use/Inactive/Underwater/Infrastructure_Eliminate/Not_a_Gage; sitestatus Active=1089/Inactive=1508; Y/N flags for stage/flow/watqual/temp; NO county column); getServiceInfo. **upstream quirks**: COUNTY stored UPPERCASE on Drinking Water; OWNER_TYPE_CODE has trailing space — handler matches both 'L' and 'L '. StreamGages caps at 1000/page server-side. Bulletin 118 is published by DWR (not SWRCB) but exposed under this connector for one-stop water context.

CAISO OASIS integration for querying market intervals, reports, and LMP datasets through PatchOps MCP.

California EPA / DTSC / OEHHA consolidated environmental connector. Probed 2026-05-02 with aggressive owner filtering — only authoritative DTSC_Admin (Envirostor + HWTS at services3.arcgis.com/Oy2JTCD10wkoelxS) and Kelsey.Ranjbar_OEHHA (CalEnviroScreen 4.0 at services1.arcgis.com/PCHfdHz4GlDNAhBb). 3 services via 5 methods: searchEnvirostorSites (~13,723 cleanup sites — 13 site_types incl. Voluntary Cleanup 1870, Evaluation 2251, Historical 2105, School Investigation 2307, Tiered Permit 1444, Military Evaluation 1175, State Response 1104, Corrective Action 728, School Cleanup 431, Federal Superfund 150, Calmortgage 154; 23 statuses; county UPPERCASE) ⭐; searchCalEnviroScreen (~8,035 census tracts with pollution-burden + population-characteristic percentile scores; CEQA-relevant disadvantaged-community overlay; PiP via {lat, lon}; filter minCIscoreP/minCIdecile) ⭐; searchHazardousWasteFacilities (~107,553 HWTS RCRA handlers — FAC_TYPES G=90,024 Generator + T=1004 Transporter + TSDF=45 + compounds; NO county column upstream); searchBrownfields (Envirostor scoped to Voluntary Cleanup + Calmortgage + School Cleanup — no standalone DTSC Brownfields Feature Service exists upstream); getServiceInfo. **upstream quirks**: Envirostor county is UPPERCASE; national_priorities_list is YES/NO/DELISTED string (not boolean); CalEnviroScreen has NO county column — keyed by 11-digit census tract GEOID; HWTS has only 11 fields with no county column. Spec drift: scoping doc said 2257 hits — most are unaffiliated AGOL clones; only 3 authoritative services exposed.

Colorado Department of Public Health & Environment (CDPHE). Front-Range air-quality monitoring (CDPHE has aggressive O&G emissions oversight), hazardous waste, voluntary cleanup, Superfund. Multi-server: AGOL hosted services on `services3.arcgis.com/66aUo8zsujfVXRIT` (CDPHE_hmwmd_admin / CDPHE_user_community / CDPHE_EJP owners) + native ArcGIS at `cohealthmaps.dphe.state.co.us` (APCD/HMWMD/WQCD/OPEN_DATA/EPHT/DEHS folders). Probed 2026-05-02. **Note**: native `maps.dphe.state.co.us` was UNREACHABLE during external probe — handler routes around it. Datasets: APCD All Active Air Pollution Emitting Facilities (~15,678 — slim 5-field schema, no County), APCD CCND Continuous Monitoring Sites (~359 — Pollutant parameter labeled per site like 'HCN', 'PM2.5'), RCRA Active Hazardous Waste Handler (~6,075 — Generator_Status: VSG=4775 / SQG=587 / N=573 / LQG=140; Active_Site is 5-char flag string H----=hazardous handler, --A--=active permit, ----S=storage), VCUP/NAD voluntary cleanup applications (~1,674 — AppStatus: APPROVAL 1465 / WITHDRAWN 56 / DENIAL 38 / PENDING 24 / INELIGIBLE 3; Applctn: NAD 1041 / VCUP 633), CDPHE Superfund / NPL Sites (~31 polygons — SiteStatus includes 'NPL ACTIVE'). VCUP layer field names are abbreviated weirdly (`CityNam` not City, `Cnss_Tr` not CensusTract, `RV_Nmbr` not ReviewNumber, `Othr_Is` not OtherIssues). Some VCUP records have geometry x=0/y=0 (no spatial location) — null'd by handler. RCRA County is UPPERCASE (`BOULDER`) — handler title-cases on output. RCRA `maxRecordCount` is 1000 (lower than other CDPHE layers' 2000). Air-pollution facility layer has only 5 fields (Airs_ID/Facility/Latitude/Longitude/Date_Data_Published) — county filter NOT exposed (would silently drop everything); use bbox/near.

Colorado Energy & Carbon Management Commission (ECMC, formerly COGCC). DJ Basin / Wattenberg / Piceance operator-side data. ECMC was renamed from COGCC in 2024 to reflect added carbon-management jurisdiction. Authoritative AGOL service is martinwi-owned `COGCC_VIEW` (same hosting org as the SLB layers — services5.arcgis.com/rqsYvPKZmvSrSWbw). Probed 2026-05-02. Layers: Well Spots (~120,701 — primary inventory), Pits (~13,683), Tank Batteries (~1,764), Directional Bottom Hole (~38,100), Directional Lines (~38,100). **Spec drift caught at probe**: searchSpills + searchSetbacks were DROPPED — ECMC does NOT publish a spills Feature Service (the data.colorado.gov dataset is `viewType=href`, just a link to the COGCC website) and the 2000ft setback is a regulatory rule, not a layer. Replacements: searchPits (env-relevant proxy) and searchDirectionalBottomHoles (Wattenberg/Niobrara horizontals). Wells layer has NO `County` text column — only `API_County` as a 3-digit FIPS subset (123=Weld, 045=Garfield, 103=Rio Blanco, 125=Yuma, 121=Washington, 001=Adams, 067=La Plata, 071=Las Animas, 075=Logan, 087=Morgan, 077=Mesa, 081=Moffat, 017=Cheyenne, 005=Arapahoe, 083=Montezuma). Handler maps both directions. Facil_Stat 2-letter codes (probed): PR=36844 (Producing), PA=23685 (Plugged & Abandoned), DA=20830 (Dry & Abandoned), AL=19458 (Abandoned Location), SI=9466 (Shut-In), XX=5229 (Closed), TA=2725 (Temp Abandoned), DG=1269 (Drilling), IJ=664 (Injecting), AC=324 (Active), WO=106, SU=56, DM=44, AB=1. Citing_Typ: ACTUAL=81259, NOTICE=2099, PLANNED=1625, HISTORICAL=383. Top operators: NOBLE ENERGY INC (9944), KERR MCGEE OIL & GAS ONSHORE LP (8960), TEP ROCKY MOUNTAIN LLC (6550), PDC ENERGY INC (6467), CAERUS PICEANCE LLC (5368). API_Label format `05-001-05000`. ECMC native server at `ecmc.state.co.us` does NOT publish an ArcGIS REST endpoint.

Colorado State Land Board — ~3M acres of state trust lands. SLB GIS publishes through the martinwi-owned ArcGIS Online org (`services5.arcgis.com/rqsYvPKZmvSrSWbw`) — same org that hosts the authoritative ECMC oil-and-gas layers (`COGCC_VIEW`). Probed 2026-05-02. **Spec drift caught at probe**: spec named the leases service `SLB_Leases_ALL_Public` — that's the AGOL item title, NOT the URL path. Actual service URL is `Leases_ALL_2021/FeatureServer/0` (legacy publish-date naming). Service path `SLB_Leases_ALL_Public` returns 404. Captured. Layers: Leases_ALL_USE (~4,568 — all current leases), SurfaceOwnership (~6,281 SLB-owned parcels), CSLB_Upcoming_Disposal_Listings (sparse — typically 1-5 active disposal tracts on layer 2; layers 0/1 return 400). Lease_Type distinct (probed): Agriculture (2281), Oil and Gas (991), Recreation (441), Solid Mineral (260), Road Access Permit (161), Temporary Access Permit (152), Other (136), No Surface Occupancy (33), Tower (32), Commercial (26), Ecosystem Services (14), Agreement (14), Ground (10), Exploration Permit (7), MOU (3), Geologic Carbon Storage (1), RE-Geothermal (1). Lease_Status: Active (4541 — overwhelming), Out for Signature (13), Pending Requirements (2). Asset_Layer: Surface (3127), Oil & Gas (972), Other Minerals (250), Coal (22). Beneficiary: School (4196 — dominant), Internal Improvements (64), Colorado State University (43), University of Colorado (20), Public Buildings (17), Multi Beneficiary (16), Saline (4), Penitentiary (4). Lease_Subtype field has 70+ values + data-quality leaks ('BILLING/LEASE END DATE', '10/1/2023', 'LESSEE') — header rows accidentally landed in the column. Exposed only as free-text filter. Transaction_Number (e.g. AG-112180) is the lease ID; Legacy_Lease_Number is older numbering (still searchable). County stored Title-Case (Yuma, Weld, Adams). Lessee names ALL CAPS upstream (`JOSEPH M. BOHNEN`).

ISO-NE integration for querying Web Services market datasets and system telemetry through PatchOps MCP.

iWell is a field-data platform for oil and gas operators. Pumpers and lease operators capture daily tank gauges, run tickets, meter readings, production, and well tests from mobile or web; managers get centralized dashboards and reporting. The API exposes the full data model so you can read and write wells, tanks, tank readings (daily and hourly), run tickets, meters, meter readings, daily production, custom fields, validation rules, notes, well tests, users, and well groups. Rate limit: 24 requests/minute per account. Date-range query params come in two flavors that are NOT interchangeable: `since` is a UNIX epoch integer (30-day lookback max), while `start`/`end` are YYYY-MM-DD strings (inclusive, 30-day window max — the published docs say 31 but the server enforces 30). When `hourly=true` on tank readings, start must equal end (same-day window). 74 read + write methods (DELETE operations intentionally omitted for safety).

Louisiana State Land Office (LSLO) AGOL Feature Service covering 1,026 state-agency land tracts. The layer is real-estate-style state holdings — LSU/McNeese/Southern campuses, state prisons, parks, DOTD rest areas, and similar facilities. Mineral interests are NOT in this layer; those route through la-sonris. Covers all 64 LA parishes; codes stored both zero-padded ('01') and unpadded ('1') upstream and the handler matches both. Handler accepts parish input as code ('10') or name ('Calcasieu' / 'St. Tammany' / 'Saint Tammany'). LEASE_OWN_ S/L/M decoded — State-Owned (839 tracts, 81%), Leased by State (150, 15%), Mixed (37, 4%). SURF_INT mostly FULL_INTEREST (1,008/1,026), 15 PART_INTEREST, 1 NO_INTEREST. USE_ exclusively 'STATE AGENCY LAND'. Department codes group tracts by state department (DOA, DOTD, LSU System, etc.). Polygon centroids computed for map handoff.

Louisiana Department of Environmental Quality (LDEQ) public AGOL Feature Services covering water-quality compliance. Search 499 IR-2020 subsegment polygons by 8-use designated-use rating (PCR, SCR, FWP, DWS, ONR, OYS, AGR, LAL × Fully Supported / Not Supported / Insufficient Data / Not a Use / No Data Collected) — 303(d)-impaired waters are the Not Supported subset. 366 assessed flowlines, 133 estuaries/lakes/wetlands, 12 watershed basins (ATCHAFALAYA, BARATARIA, CALCASIEU, MERMENTAU, MISSISSIPPI, OUACHITA, PEARL, PONTCHARTRAIN, RED, SABINE, TERREBONNE, VERMILION-TECHE). Plus 761 LEAU-roster active ambient monitoring sites and 62 fish-consumption advisories. Subsegments + flowlines have no parish column upstream — filter by BASIN or bbox/near. Fish Advisories carry a free-text Parishes string (handler LIKE-matches). Air emissions and hazardous-waste services do NOT exist as LDEQ-owned Feature Services — use TCEQ-equivalent Federal data via airnow / envirofacts for those domains.

Louisiana SONRIS / DNR (rebranded to DCE — Department of Conservation & Energy) public ArcGIS REST FeatureServer covering oil & gas. Filter ~245,450 wells by parish, operator, status (mapped via LEGEND_DES — the human-readable label, since WELL_STATU is opaque numeric codes like '03' or '29'), or product type (oil/gas/injection). Salt domes (174) are LA-specific — caverns, sour gas storage, SPR. Oil & gas fields (~11K polygons) carry FIELDNAME only — no parish or operator. Injection / storage / service wells (~4.5K) include type, status, operator. The legacy native sonris-www.dnr.state.la.us ArcGIS server is now 404 (LA rebranded DNR to DCE); the working data lives on AGOL mirrors. Parishes returned in Title Case (LA SALLE → La Salle). SONRIS production database is browser-session only — wells include `sonrisLink` for downstream UIs to deep-link.

Access the National Weather Service API for weather alerts, point forecasts, hourly forecasts, and station observations. Essential for field operations planning, severe weather monitoring, and HSE compliance.

North Dakota Department of Environmental Quality (ND DEQ) public ArcGIS surface + FracTracker mirror. **Major spec drift caught at probe**: ND DEQ does NOT publish spills, USTs, air permits, or abandoned brine pits as Feature Services on AGOL — methods reframed against the agency's actual published layers plus the long-cited FracTracker spill mirror (third-party, ~5,367 records, 2014-era extract — only programmatic ND O&G spill source). What ND DEQ DOES publish: ~2,950 Construction Stormwater permits (~2,944 Active) — operator name searchable (`envintName`), Bakken well-pad construction permits visible (Burlington Resources, Continental Resources, Hess, etc.); ~278 Groundwater Monitoring polygons (Agricultural / Western / Not Sampled); ~34,849 assessed stream reaches with 303(d) Category labels (Cat 5/5A = TMDL needed/underway, Cat 4A = TMDL complete); plus lakes/BMPs/319-projects ancillary. Stormwater layer has NO COUNTY column — county filter silently ignored, use bbox/near. Brine + crude oil spill services share the same upstream dataset; handler dedupes by Incident_ID when spillType:'all'. Field naming is mixed-case across layers (camelCase `envintName`/`swsStatus`, ALL CAPS `NAME`/`Program`/`CATEGORY`).

North Dakota Department of Trust Lands (NDDTL) AGOL Feature Services covering state-trust mineral and surface land tracts. ~33,273 mineral tracts (8,911 Leased / 24,348 Available / 14 Not Available) — oil & gas leases identified by `OG-YYYY-NNNNN` lease prefix in the composite `lease` descriptor (e.g. `Golden Valley - 138-104-36-NE4 - OG-2025-13594`). NDDTL does not publish OG-leases as a separate layer; handler filters with `UPPER(lease) LIKE '%OG-%'` plus `eligible='Leased'`. ~4,888 surface tracts (mostly grazing/ag — `AG-` prefix; LESSEE field heavy on grazing associations). Two surface-layer variants: a thin view and the richer Trust_Land_Surface (LESSEE / ANNUAL_RENT / PUBLIC_ACCESS / LEASE_EXPIRATION as epoch-ms). `effective`/`exp` on minerals view stored as MM/DD/YYYY string (with single-space ' ' for null) — handler normalizes to ISO. Counties stored Title-Case (different from ND DMR's UPPERCASE). Top operators: Continental Resources, Phoenix Energy One, Petro-Sentinel, Kraken, OKreek, XTO, Topaz Energy. landtrustdash.nd.gov referenced in spec is offline; AGOL views are the working public surface. McKenzie / Mountrail / Williams counties dominate active OG-leases.

North Dakota Industrial Commission Department of Mineral Resources (NDIC DMR) public oil & gas data. The native dmr.nd.gov fee services are paywalled (HTTP 401); the AGOL `sbogan_worldmap` mirror exposes the public extracts. ~25,539 wells with 14-digit hyphenated `api_no`, full PLSS (`twp`/`rng`/`sec`/`qq`) queryable, status enum (A=8,973 / PA=3,786 / DRY=6,163 / Confidential=2,039 in 6-month tight-hole window / DRL=356 / LOC=342 / IA=572 / TA=354), well-type enum (OG=21,410 / SWD=648 / WI=766 / GASD/GASC/GASN). County stored UPPERCASE — handler queries with `UPPER(County)='X'` and Title-Cases on output. ~15,861 horizontal-leg polylines (sparse upstream, only `linekey` = `<api>_LATn`). Companion `ND_Wells` layer carries cumulative `TotalOil`/`TotalWater`/`TotalGas` aggregates; `searchProductionByField` joins by FileNo. Spills come from the FracTracker `NDBrineSpills` + `NorthDakotaCrudeOilSpills` mirror (~5,367 records each — same upstream dataset, 2014-era extract). McKenzie / Williams / Mountrail counties dominate the Bakken core.

NESO integration for querying Data Portal package and datastore resources through PatchOps MCP.

Access the NETL Energy Data eXchange (EDX) for US Department of Energy fossil energy R&D datasets. Search for well logs, core analysis data, seismic surveys, geological surveys, and carbon storage / CCUS site characterizations. Browse organizations, groups, and individual resources.

New Mexico State Land Office (NMSLO) public ArcGIS REST FeatureServer covering state-trust mineral leases — the Permian Basin parallel to TX GLO. ~5,908 Active Oil & Gas Leases, ~746 Active Mineral Leases (with LEASE_TYPE: Salt Water Disposal, Water, Caliche, Sand & Gravel, Potash, General Mining, Special Use Agreements, Salt, Coal, Geothermal), ~3,765 Active Agricultural Leases, ~1,233 Active Commercial Leases. Each lease record carries lessee (OGRID_NAM), gross acres (LSE_ACRG), effective date (VEREFF_DTE), term-end date (VERTRM_DTE), and polygon geometry. NMSLO publishes only ACTIVE leases — there is no historical / pending layer. The legacy wheeler.nmstatelands.org ArcGIS server is offline. NO COUNTY column on any layer — county filtering must be expressed as bounding boxes (we expose bbox + near). Held-by-production leases have term-end at year-9999 epoch; we surface daysUntilExpiry as null for those. Lease numbers are split across LSE_PREFIX + LSE_NUMBER + LSE_SUFFIX, concatenated into UNIQUEKEY (e.g. 'B031960005').

New Mexico Oil Conservation Division (OCD) public ArcGIS data — 140K+ wells, facilities (C-141 incidents), and induced-seismicity response areas. Half the Permian basin sits in NM; this is the regulator's authoritative source for permits, completions, and compliance signal. No authentication required.

New Mexico Office of the State Engineer (NM OSE) AGOL Feature Services covering NM water rights and groundwater administration. ~277,608 Points of Diversion (POD) — water-rights records keyed by basin code (RG=Rio Grande, RA=Roswell Artesian, L=Lea County, ...), county code (LE=Lea, ED=Eddy, SJ=San Juan), beneficial-use code (OIL/OFM/SRO/MIN/INJ for O&G; DOM/DOL/IRR/MUN for general; 59 codes total), water-right status (PMT=Permit, LIC=License, ACT/EXP/CAN/...; 20 codes), and POD physical status (ACT/INC/PEN/PLG; 7 codes). 39-poly canonical Declared Groundwater Basins layer + opt-in 161-poly with-extensions layer including sub-basins, declared dates, and well-spacing flags. 74 irrigation districts. Owners returned as last+first; handler accepts county input as either 2-letter code (LE) or full name (Lea / Doña Ana / Dona Ana). POD geometry stored upstream as UTM Zone 13N (NAD83) — outSR=4326 forces WGS84 for lat/lon output.

New Mexico Environment Department (NMED) native ArcGIS REST FeatureServers at mercator.env.nm.gov. ~1,124 Ground Water Discharge Permits (Permian-relevant — Industrial, UIC/Industrial, Domestic, Reuse waste types; ~37 active in Lea, ~37 active in Eddy). Air Facilities split across 7 layers by class: Major-Title V (~37K), Minor (~137K), Synthetic Minor (~613K), No Permit Required (~108K), Notice of Exemption (~23K), Notice of Intent (~918K), Nonactive (~724K). 21 RCRA-permitted Hazardous Waste Facilities (DoD bases, USDOE labs, big industrial — no county column). ~163 Voluntary Remediation Program sites with brownfield-style cleanup history. STATUS values upstream are dirty (GWDP has 13 distinct, VRP has Termin/ActIve/Closed/closed/Condit/Applic/CCOC) — handler does case-insensitive matching. Counties returned in Title Case (Lea, Dona Ana, San Juan).

Access NOAA Center for Operational Oceanographic Products and Services (CO-OPS) data including tide predictions, real-time water levels, meteorological observations, and ocean currents. Essential for offshore operations, coastal facility planning, and marine logistics.

Covers exploration, mining permits, and mining licences primarily in the Taranaki Basin (NZ's only producing onshore/offshore basin). Well data includes type, content (oil/gas/dry), status, spud and completion dates, and depths. Production volumes are published separately by MBIE as PDF/Excel; this connector covers spatial and regulatory data. Toggle on and use — no setup needed.

Ohio ODNR Division of Geological Survey (DGS). Probed 2026-05-02. Native server at `gis.ohiodnr.gov/arcgis/rest/services/DGS_Services` — 14 MapServers in catalog, 6 layers consumed: Ohio_Water_Wells/1 'Well Logs' (~651,613 — water-well log inventory; layer 0 'Sealing Reports' has ~46,789 abandoned reports but Layer 1 is the primary inventory), USDW_Features/4 'USDW Areas' (~189 polygons — UIC injection-zone protection analog; distinct values: Berea Sandstone=169, Lockport Dolomite=11, Sharon Sandstone or deepest sandstone unit above the Berea=2, Black Hand Sandstone=1, Black Hand Sandstone absent=1, Not mapped=5), USDW_Features/2 'USDW Boundaries' (~5 polylines — fresh/saltwater interface lines), Earthquakes_EB/4 (~1,181 instrumental epicenters since 1968), Earthquakes_EB/3 (~1,007 historical epicenters), Karst_InteractiveMap/4 (~46,789 karst points). **Spec drift caught at probe**: searchMineralLocations DROPPED — DGS_Services/Mineral_Industry_Locations_AGOL returns HTTP 500 on EVERY query (every where-clause variant attempted, both MapServer/0 and FeatureServer/0). Layer is broken upstream; documented in handler comments and getServiceInfo._droppedMethods. upstream quirks: COUNTY_DESC on Water Wells UPPERCASE ('DELAWARE', 'BELMONT'); WELL_USE_DESC distinct top values DOMESTIC=490,194, MONITOR=42,385, AGRIC/IRRIG=14,285, DEWATERING=3,318, INDUSTRIAL=1,748, COMMERCIAL=1,687, INJECTION/DISPO=478 (handler matches via UPPER LIKE). AQUIFER_TYPE_DESC has 200+ free-text values. Karst POINT_TYPE strings have trailing whitespace ('Spring - Field Verified ', 'Spring - Suspect-NotVisited') — handler trims. Earthquakes_EB DATE column is epoch-ms while YEAR_/MO/DA are floats — handler returns both. maxRecordCount varies: water_wells=2000, USDW=1000, Karst=2000, Earthquakes=2000.

Ohio ODNR Division of Oil & Gas Resources Management (DOGRM). Marcellus + Utica operator side — Eclipse Resources, Encino Energy, Ascent Resources Utica, EAP Ohio (Eclipse acquired). Probed 2026-05-02. Native server at `gis.ohiodnr.gov/arcgis/rest/services/DOG_Services` — 6 working layers consumed: Oilgas_Wells_public/0 (~242,071 — primary inventory, ALL O&G wells regardless of status), Oilgas_Wells_public/4 (~4,606 horizontal wellheads — Utica/Marcellus laterals), Oilgas_Wells_public/6 (~4,299 horizontal lateral polylines), WellPads/1 (~1,169 well-pad polygons), Unitization_DrillingUnits/1 (~1,007 horizontal drilling-unit polygons), Oilgas_Fields/0 (~2,971 field polygons w/ PROD_TYPE GAS=2262/OIL=702/CBM=7). upstream quirks (probed): **WL_CNTY column UPPERCASE** on wells (88 distinct counties — BELMONT 3,228 wells, CARROLL 3,922, ASHLAND 5,960, ALLEN 4,848); County stored Title Case on WellPads/1 (different casing — handler accommodates both). SLANT distinct codes V=236,357 (97.6%), H=4,679, D=858, O=177 — handler accepts code or descriptive substring. WL_STATUS_DESC has 15 distinct descriptive strings (top: Plugged and Abandoned=68,143, Producing=60,854, Final Restoration=39,053, Unknown status=26,821, Expired Permit=23,374, Well Drilled=10,809, Permit Expired=4,448, Storage Well=3,169, Orphan Well - Ready=2,326, Active Injection=400, Well Permitted=183) — handler matches via UPPER LIKE. Utica_Shale + Marcellus_Shale are 0/1 doubles surfaced as boolean utica/marcellus on output. OrphanWellProgramStatus has trailing whitespace variants ('Referred ', 'LOPTC ') — handler trims for comparison. maxRecordCount=1000 advertised AND enforced. Spec methods searchOilGasFields, searchHorizontalWells, searchDrillingUnits, searchWellPads all working; Oilgas_CoreSamples + NotificationAreas catalog-present but low-value for operator workflows (skipped). InspectorWellHead_Coords FeatureServer is internal-inspector data (skipped).

Ohio EPA environmental compliance connector. Probed 2026-05-02. Spec drift: scoping doc warned that AGOL search via owner `portaladmin11` returned 262 hits but 'many were third-party — filter strictly to authoritative Ohio EPA-published'. Probe found the agency native server at `geo.epa.ohio.gov/arcgis/rest/services/` with 19 thematic folders. All 4 layers used here are agency-native (NOT third-party AGOL mirrors). Layers: EmergResponse/Spills2_Public/1 'Spill Sites and Products' (~16,157 — broad spills+products view; layer 0 is sites-only, narrower; handler uses layer 1 since it links spill product details), Derr/TBA_Sites_Public/0 (~217 — DERR Targeted Brownfield Assessment grant sites — Division of Environmental Response & Revitalization), SurfaceWater/NPDES/0 'Individual Permits' (~3,148 active — Industrial=1,032, Public=2,116; permit_status always 'ACTIVE'; district distinct: NEDO=1,124, NWDO=711, SEDO=516, SWDO=495, CDO=294, OUTS=8), geopol/Boundaries_WM/2 'OEPA Districts WM' (5 polygons — CDO/NEDO/NWDO/SEDO/SWDO with one ESW outlier in spills data). upstream quirks (probed): Spills2_Public layer 1 `county` column is **Title Case with TRAILING WHITESPACE** ('Tuscarawas ', 'Belmont ') — handler uses LIKE 'X%' to handle. `reportedproduct` similarly space-padded to ~75 chars (handler trims output). `oepadist` has 7 distinct values: SEDO=1928, CDO=2310, NEDO=4499, SWDO=3019, NWDO=3680, ESW =5, NULL=716 (some with trailing whitespace, some literal 'NULL' string — handler normalizes). NPDES `county` is Title Case 'Belmont' (NO trailing whitespace — different from Spills). All 3 native MapServers use **lowercase** `objectid` as OID — different from most ArcGIS REST services. Brownfields layer has **NO county column** — county filter only on Spills + NPDES; Brownfields uses bbox/near for spatial scoping. getEPADistrict implemented as point-in-polygon query against geopol/Boundaries_WM/2. maxRecordCount: spills=2000, brownfields=2000, npdes=4000, districts=1000.

Access real-time and historical pricing for Brent crude, WTI, OPEC basket, natural gas, RBOB gasoline, diesel, heating oil, and NGL-related commodities. Includes latest quotes, past day/week/month/year price history, and grouped convenience methods for oil and gas pricing. PatchOps can fall back to a limited demo response when no API key is configured, but full access requires a key.

Oklahoma Department of Environmental Quality (OK DEQ) native ArcGIS REST MapServers at gis.deq.ok.gov. ~5,911 Wellhead Protection Area (WHPA) polygons — drilling-restriction overlays around public water supplies, ZONE A (innermost) / B / C (outermost) — no name or county upstream, just SOURCE_IND. ~890 Remediation Institutional Controls under formal cleanup programs (Brownfields, RCRA, SCAP, Superfund, VCP, Solid Waste). Voluntary Cleanup Program site list. ~151 state-accredited labs (Lab_Type: Commercial, Field, Industrial, Municipal, Permittee — with upstream typos like Muncipality vs Municipal). 28 air-quality monitoring sites tracking O3, PM2.5, NO2, SO2, CO, Hg, Lead, and Toxics. Counties returned in Title Case; handler strips trailing ' County' from upstream values like 'Tulsa County'.

Oklahoma Water Resources Board (OK OWRB) native ArcGIS REST + AGOL Feature Services covering OK groundwater + flood-hazard data. 71 aquifer polygons across 4 leaf layers — Major Bedrock (15 — Garber-Wellington, Antlers, Roubidoux, Arbuckle-Simpson), Minor Bedrock (20), Major Alluvial (21 — Canadian River, Cimarron, North Fork Red River), Minor Alluvial (15). For O&G produced-water injection-zone analysis, target Major Bedrock by name. ~23,539 FEMA NFHL Special Flood Hazard Area polygons (FLD_ZONE: X=10K, AE=10.6K, A=2.7K, AO/AH minimal; ZONE_SUBTY: 0.2 PCT, FLOODWAY, etc.) — OWRB-published, includes BFE and depth attributes. ~10,749 Stream Fish Count observations across 26 fish-group taxonomic families (Centrarchidae sunfish/bass top, Cyprinidae minnows, Ictaluridae catfish) with sportFish flag. Aquifer GIS uses lowercase field names (name/class/type/label_code) — handler accommodates. None of these layers carry a county column upstream — geo filtering is bbox or near.

Oklahoma Commissioners of the Land Office (OK CLO) public ArcGIS REST FeatureServer covering state-trust real estate + mineral leases — the SCOOP/STACK parallel to TX GLO and NMSLO. Real Estate Leases (~2,885) are split across LeaseType: Agricultural, Short-term Commercial, Long-term Commercial. Each carries Lease number, ContractNumber, BeginDate/EndDate (ISO YYYY-MM-DD strings — server-side date filtering works), CountyName, Legal description, TotalAllAcreage, OwnerName. Mineral Leases (~4,500) include both ACTIVE and EXPIRED rows — pass activeOnly=true (default on mineral) to filter to currently-active. Mineral leases carry TrustName (Common Schools, University of Oklahoma, Oklahoma State University, Public Building, etc.) and STRM legal location. The Expiring Real Estate Leases layer (~580) is upstream-curated. CountyName is UPPERCASE upstream (KAY, ROGER MILLS) — we Title-Case on output. The Field Data well inventory (~576K) is an OCC well-data mirror, exposed for completeness but not specific to trust lands.

Live queries against the Oklahoma Corporation Commission's public ArcGIS REST — no auth, no ETL. 26 methods total: 24 named convenience methods cover the high-value layers — wells (RBDMS, orphan, state-funds, well logs), completions, horizontal laterals, UIC wells (with commercial-only flag), permits (Intent-to-Drill), drilling/spacing units, field rules, surface facilities, oil & gas incidents, gas storage, PST tanks/releases, induced-seismicity zones (AOI / reduction areas / HF AOI), hydrology (rivers/streams/lakes/aquifers), base-of-treatable-water, public water supply, groundwater wells, sedimentary basins, PLSS cadastral, and OCC districts. Plus 2 generic methods: queryLayer({ layer, where, bbox, ... }) exposes every layer in the catalog and listLayers() returns the key list — together they cover the long tail (risk overlays, recycling pits, ECRS incidents, federal land, etc.) without needing 50 hand-tuned methods. Each method returns features plus a ready-to-render GeoJSON FeatureCollection that plugs straight into the persistent map. Production volumes are NOT at OCC — those live with the Oklahoma Tax Commission and are out of scope.

Access Open-Meteo's free weather API for global forecasts, historical weather data, air quality indices, and marine weather. Supports hourly and daily variables including temperature, precipitation, wind, and soil conditions.

Pennsylvania Department of Environmental Protection — Bureau of Oil & Gas Management. PA's quirk: O&G regulator lives under DEP (the environmental agency), not a separate Railroad Commission analog. ~25,039 Unconventional Wells (Marcellus + Utica horizontals — Range Resources Appalachia, EQT, Coterra dominant). ~198,856 Conventional Wells (legacy vertical oil + gas). PA does NOT use a 14-digit API number — wells keyed by `PERMIT_NUMBER` like `003-22621` (county prefix + sequential). WELL_STATUS distinct values (probed): Active (104,612), Plugged OG Well (52,035), Operator Reported Not Drilled (26,816), DEP Abandoned List (14,979), Proposed But Never Materialized (8,071), DEP Orphan List (6,341), Abandoned (6,101), DEP Plugged (3,746), Cannot Be Located, Regulatory Inactive Status, Duplicate, Uncharted Mined Through. WELL_CONFIG_CODE: Vertical Well (199K conv), Horizontal Well (23K unconv), Deviated Well, Undetermined. WELL_TYPE: GAS (112K), OIL (70.7K), COMB. OIL&GAS, INJECTION, COALBED METHANE, STORAGE WELL. ~27,421 Abandoned and Orphaned Wells (DEP Orphan List + DEP Abandoned List + Abandoned). DEP does NOT publish a violations Feature Service — eFACTS is web-UI only. Complaints layer (~39,305) used as proxy: TYPE_DESC includes Mine Subsidence (9,865), Water Contamination (5,660), Land Contamination (5,369), Air Contamination (4,337), Spill Response, etc. Production reports are NOT a Feature Service either — distributed as XML feeds at greenport.pa.gov; spec method `searchProductionReports` was dropped. Washington / Bradford / Susquehanna / Greene counties dominate Marcellus core.

Pennsylvania Department of Environmental Protection — environmental side (water, mining, hazardous waste, air). Same agency as `pa-dep-oilgas`, separate set of layers on the eMapPA External MapServer. ~95,191 Impaired Streams Assessments — layer 158 contains ONLY impaired records (BLN_ATTAINED='N'), so this is the 303(d)-equivalent feed. STR_ASSESSED_USE_DESC: Aquatic Life (46.5K) / Recreational (33.4K) / Fish Consumption (14.9K) / Potable Water Supply (443). SOURCE_CAUSE is free-text concat of pollutant + cause (top: SOURCE UNKNOWN - PATHOGENS, ACID MINE DRAINAGE - METALS, AGRICULTURE - SILTATION, ATMOSPHERIC DEPOSITION - MERCURY). Mine permits split across 3 layers — Anthracite (~2,362) / Bituminous (~38,477) / Industrial Mineral (~1,839). PERMIT_TYP is freeform with 90+ distinct values + typos ('Refuse Reprossing'). Layers 76/77/79 have NO COUNTY column — county filter silently drops, use bbox/near or companyName/mineName. Land Recycling Cleanup — Soil Media (~16,920) used as the hazardous-waste proxy (largest of 7 cleanup-media sub-layers; SUB_FACILITY_TYPE includes SOIL MEDIA, GROUNDWATER MEDIA, SEDIMENT MEDIA, etc.). Point of Air Emission (~61,291) — stack-level emission points; PRIMARY_FACILITY_TYPE='AIR EMISSION PLANT' is the only value, so useful filters are companyName / siteStatus / complianceOnly. SITE_STATUS values inconsistent — UPPERCASE on most ('ACTIVE', 'INACTIVE', 'ABANDONED', 'RECLAMATION COMPLETED') with one upstream typo 'Unavaialble'. NO COUNTY column on hazardous waste / air emission layers either.

Pennsylvania Department of Conservation and Natural Resources — Bureau of Forestry. **Major spec drift caught at probe**: DCNR does NOT publish state-forest mineral leases as a Feature Service (lessee/operator data is in PDF leases only). The spec method `searchStateForestLeases` was reframed to `searchOilGasInfrastructure` against the BOF/OilGasInfrastructure MapServer (Pads + Pipelines layers — the geometry footprint of leased activity). What DCNR DOES publish: ~941 Pads polygons (Pad_Type domain — gas well 685, Monitoring 152, freshwater impoundment 44, compressor 26, Stone Pit/Quarry 18, etc.), ~762 Pipelines polylines (Pipeline_Type — Gathering / Marketing / Water / Trunk / Other / Meter-Valve-Tap), ~661 State Forest polygons keyed by SF_Name (Susquehannock, Tioga, Cornplanter, Loyalsock, etc.), 20 Forest District admin units, ~124 State Park boundaries (TYPE: STATE PARK 114, CONSERVATION AREA 3, ENVIRONMENTAL EDUCATION CENTER 4, PRESERVE 1, FARM PARK 1). Pad_Type / Status / Pipeline_Type are SmallInteger codes — handler decodes via published domains. Status: 1=proposed-draft, 2=approved, 3=under construction, 4=construction complete (478 pads), 5=rejected, 6=plugged, 7=reclaimed (102 pads), 8=abandoned, 9=inactive (22 pads), 10=Active (339 pads), 11=Removed Completely, 12=Withdrawn by Operator. Pads layer carries NO operator name (Pipelines does — `Operator` field). District 16 (Tioga) and District 20 (Loyalsock) have the densest Marcellus development.
