One skill, three state adapters. Finds tax-delinquent, dormant, or severed
One skill, three state adapters. Finds tax-delinquent, dormant, or severed mineral parcels near active Marcellus/Utica wells by routing to the appropriate public ArcGIS REST service for West Virginia, Pennsylvania, or Ohio. Each state has different data available — WV has a statewide delinquent-properties layer, OH has explicit 200-series mineral land-use codes, and PA has neither but supports parcel–well spatial correlation with owner-name heuristics.
None required. All ArcGIS REST services in this skill are publicly
accessible with no API key or authentication. WVDEP uses a self-signed SSL
certificate and requires -k with curl; WVU GIS, PA DEP, OGRIP, and ODNR
have valid certificates.
Step 1 of every invocation is choosing the adapter. Map the user's request to one or more states, then follow that adapter's workflow.
| User Cue | Route To | Rationale |
|---|---|---|
| "Tyler County", "Marshall", "Doddridge", "Wetzel" WV, "delinquent mineral" | WV | WV has statewide delinquent layer |
| "Greene County", "Washington County" (PA), "Bradford", "Tioga", "Third Strata" | PA | PA parcels + unconventional wells |
| "Belmont", "Harrison", "Carroll", "Monroe", "Noble", "Guernsey", "Columbiana", "Jefferson" | OH | OGRIP StateLUC 200-series |
| "Marcellus core", "Appalachian play" (no state) | All three, run sequentially | Cross-state scan |
| "Dormant Mineral Act" alone | OH first (ORC 5301.56), then PA (58 P.S. 521) | No WV analogue |
| "Sheriff sale", "no bid", "state deed" | WV | Only WV exposes tax-sale lifecycle in GIS |
| "StateLUC", "OGRIP", "200-series" | OH | OH-specific feature |

WV is the only state of the three with a unified delinquent-properties GIS layer (32,749 records statewide). Severed mineral estates are common under WV law and routinely become tax-delinquent when mineral owners lose track of inherited interests.

enumerations, mineral keyword coverage, dormant-mineral statute notes (WV has
no dedicated dormant-mineral act — use the tax-delinquent path instead), and
the full workflow.
PA has no statewide delinquent-properties GIS layer. County Tax Claim Bureaus hold that data as PDFs or county-specific portals. Instead, this adapter spatially correlates PA DEP Parcels (4.6M) with PA DEP Oil/Gas Wells (223K), filters to active unconventional wells, and flags mineral-interest indicators through owner-name patterns.
PA law recognizes three mineral strata — surface, coal, and oil/gas — which
can each have different owners and different tax assessments. An OWNER_NAME
in the DEP Parcels layer may represent any one of the three. Coding is not
standardized across PA's 67 counties, so county assessment records are the
only authoritative source for stratum-level ownership.
If a severed mineral interest has seen no title transaction, lease, or production in 20 years, the surface owner may petition to extinguish it. This is especially relevant for "HEIRS" and "ET AL" parcels near active wells.
| Pattern | Indicates |
|---|---|
OWNER_NAME LIKE '%ENERGY%' | E&P company |
OWNER_NAME LIKE '%GAS%' | Gas company |
OWNER_NAME LIKE '%OIL%' | Oil company |
OWNER_NAME LIKE '%RESOURCES%' | Resource company |
OWNER_NAME LIKE '%MINERAL%' | Mineral trust |
OWNER_NAME LIKE '%HEIRS%' | Inherited estate (possible severed) |

After spatial correlation and owner-name flagging, direct users to:

Ohio is the easiest of the three states because OGRIP parcels carry explicit
200-series StateLUC codes for mineral parcels. No text parsing needed.
| Code | Description | Category | Target? |
|---|---|---|---|
| 200 | Min-Custom Code | General | Yes |
| 210 | Min-Coal Land (surface + rights) | Coal | Secondary |
| 220 | Min-Coal Rights-Working Interest | Coal | Secondary |
| 230 | Min-Coal Rights-Separate Royalty Interest | Coal | Secondary |
| 240 | Min-Oil and Gas-Working Interest | Oil & Gas | Primary |
| 250 | Min-Oil and Gas-Separate Royalty Interest | Oil & Gas | Primary |
| 260 | Min-Other Minerals | Other | Secondary |
| 261 | Min-Custom Code | Other | Yes |
| 270 | Min-Custom Code | General | Yes |
Filter patterns:
StateLUC IN ('240','250')StateLUC LIKE '2%'StateLUC IN ('210','220','230')A mineral interest may be deemed abandoned if, during the preceding 20 years, NONE of the following "savings events" have occurred: title transaction, mineral tax filing, mineral production, mining/drilling permit, unitization order, claim to preserve, or known-owner identification.
Use ODNR.Last_Nonzero_Production_Year as the data-side indicator. If the
value is 20+ years ago and no active/permitted wells exist within 2 miles,
flag the parcel for title examination.

Regardless of state, every run follows five steps.
Run the state-appropriate parcel query with geometry (returnGeometry=true,
outSR=4326) so Step 4 can do spatial correlation.
Delinquent_Properties/0 with FullLegalDescription LIKE '%MINERAL%' + status filter.PA_Parcels/0 filtered by COUNTY_NAME — geometry + owner name.OhioStatewidePacels_full_view/0 with StateLUC LIKE '2%' or StateLUC IN ('240','250').Always check count first. Warn the user if the result set exceeds the service's record limit.
Delinquent_Properties to ParcelSummary Table 11 on
CleanParcelID in batches of 50 IDs.PIN ↔ LocalParcelID for OWNER1/OWNER2,
and surface CAMADataSite URL for the county auditor.For each parcel with geometry, buffer (1 mile default, 2 miles for dormant screening) and query the state's well layer:
wellstatus='Active Well' (use curl -k).UNCONVENTIONAL_IND='Yes' AND WELL_STATUS='Active'.WL_STATUS_DESC='Producing'; for dormant screening
drop the status filter and inspect Last_Nonzero_Production_Year.Deduplicate wells across parcels. Cap well queries to the most promising parcels (largest acreage, actionable status) to avoid rate-limit issues.
One table, one narrative, regardless of state. Include a state column so
multi-state runs stay legible.

Mineral identification is not uniform across states. WV and PA rely on text parsing of legal descriptions or owner names (false positives from geographic names like "COAL RIVER"). OH uses explicit StateLUC 200-series codes but coverage is uneven in non-Utica counties. Treat all results as candidates, not confirmations.
Delinquent-data availability is asymmetric. WV has a statewide GIS layer. PA has 67 county Tax Claim Bureaus with no unified API. OH has fragmented county-level data; Stark and Cuyahoga expose GIS, but the eight Utica-core counties don't.
$0 appraisals are normal for severed minerals. Many mineral estates
are not separately assessed. TotalAppraisal=0 in WV or empty values in
OH do not mean the rights are worthless.
Centroid vs. polygon. WV Delinquent Layer 0 and PA DEP Parcels provide point centroids. The subsurface mineral boundary may not align. For polygon geometry use WV Delinquent Layer 1, PASDA for PA, or OGRIP (polygon-capable).
Horizontal laterals extend beyond 1-mile buffers. Marcellus/Utica laterals run 5,000–15,000+ feet from the surface pad. Use 2-mile buffers when comprehensive capture is needed.
Dormant mineral statutes vary. OH's ORC 5301.56 (amended 2006) and PA's 58 P.S. 521.1–521.8 have different savings-event rules and notice requirements. WV has no dedicated dormant-mineral act — use the tax-delinquent pathway instead.
County name format differs across sources. OGRIP uses uppercase ("BELMONT"), ODNR mixed case ("Belmont"), WV Delinquent mixed case ("Tyler"), WVDEP wells 3-digit FIPS ("095"), PA DEP Parcels and Wells mixed case. Normalize before cross-joining.
Owner-name heuristics are heuristics. "CONSOL ENERGY" on a PA parcel might be surface, coal, or oil/gas — the Third Strata Doctrine means any of the three. County assessment records are the only authoritative source.
Data freshness varies. WVDEP production data reflects last update; OIT is 2022 vintage; delinquent statuses can change between sheriff sales. Always verify critical records with the originating county.
Legal vs. research use. This skill provides screening data for research. It does not constitute legal or investment advice. Title search, quiet title actions, Dormant Mineral Act proceedings, and county-level due diligence require licensed counsel.
