How to look up a well in your state.

Oklahoma

Oklahoma Corporation Commission

Free and no registration, but the records are split across several separate search cabinets: wells, logs, production, and case files each have their own form. Case filings before and after March 21, 2022 live in different cabinets.

Texas

Railroad Commission of Texas

Texas reports oil production by lease rather than by well, so a single well's oil volume often is not broken out. Land is described by abstract and survey, not section-township-range. Searching imaged records is free; downloads and certified copies cost per page.

New Mexico

Oil Conservation Division, EMNRD

The permitting app runs a browser check before loading, so it works in Chrome or Safari but not in some privacy browsers. Searching by API number is the most reliable path.

Kansas

Kansas Corporation Commission, with data hosted by the Kansas Geological Survey

Kansas splits the job: the Corporation Commission regulates, but the actual well and production databases live at the Kansas Geological Survey. Start at KGS. The KCC site has a certificate quirk that some browsers flag; the KGS links are clean.

North Dakota

North Dakota Industrial Commission, Department of Mineral Resources

North Dakota is the only state on this page that charges. Well search, the map, and statewide statistics are free, but per-well production, scout tickets, and well files require a subscription, $100 a year for basic or $500 for premium as of January 2026.

Colorado

Colorado Energy and Carbon Management Commission

The agency was the COGCC until 2023, so older bookmarks and articles use that name. The query tools still run on the legacy state domain while the main site is on colorado.gov. API number works best.

Wyoming

Wyoming Oil and Gas Conservation Commission

The WOGCC homepage has no data tools on it. Everything lives in Data Explorer, which holds wells, production, imaged files, and mapping in one app. The old pipeline.wyo.gov queries still work and are faster if you have an API number.

Montana

Montana Board of Oil and Gas Conservation

The old bogc.dnrc.mt.gov address is dead, so any bookmark you have from a few years ago will fail. Production and scanned well files are reached from inside Data Miner rather than at their own addresses.

Utah

Utah Division of Oil, Gas and Mining

Utah has said the LiveData search tools are being phased out for a newer explorer, so these addresses are the most likely on this page to change. If a link fails, start at the data portal home.

Louisiana

Louisiana Department of Conservation and Energy, Office of Conservation

Everything runs through SONRIS, one dated but comprehensive portal covering wells, production, imaged documents, and mapping. Some entry paths show a CAPTCHA. The department has been renamed twice recently, so old DNR links redirect.

Arkansas

Arkansas Oil and Gas Commission

Start with Data Explorer, which is the cleanest entry point. The main AOGC site sits behind a bot filter that can block VPNs and some browsers; scanned files live in document imaging cabinets reached from its menu.

California

California Geologic Energy Management Division

CalGEM was DOGGR until 2020, and the old Well Finder has been folded into WellSTAR. Production records and imaged well files are both reached inside WellSTAR rather than at separate addresses.

West Virginia

WV Department of Environmental Protection, with records at the WV Geological Survey

Another split state: DEP handles permits and the well search, but historical records, scanned logs, and searchable production live at the Geological Survey. For what a well produced, go to WVGES, not DEP.

Ohio

Ohio Department of Natural Resources, Division of Oil and Gas Resources Management

Ohio moved off its old oilandgas.ohiodnr.gov domain and many older deep links are dead. Ohio reports production quarterly rather than monthly, so recent months lag.

Pennsylvania

Pennsylvania Department of Environmental Protection, Office of Oil and Gas Management

Pennsylvania is report-driven rather than search-driven: you pick a report and filter it, which is less intuitive than most states. Conventional shallow-well production was only reported annually until recently, so older records are sparse.

Michigan

Michigan Department of Environment, Great Lakes, and Energy

GeoWebFace is the one tool worth knowing: it is the map, the well record lookup, and the scanned document viewer at once. Careful with Michigan's Wellogic system, which covers water wells, not oil and gas.

Mississippi

Mississippi State Oil and Gas Board

The tools open in windows inside a single page, so the back button behaves oddly but the searches work. Mississippi also publishes its wells to the free WellFinder mobile app, which is handy for finding wells near a specific piece of ground.

Alabama

State Oil and Gas Board of Alabama

Alabama keys its records on permit number rather than API number, which trips up owners coming from other states. Production lookup is batch oriented: you feed it permit numbers and it returns a spreadsheet.

Kentucky

Division of Oil and Gas, with records at the Kentucky Geological Survey

The Division of Oil and Gas issues permits but publishes no searchable well database of its own; the Kentucky Geological Survey hosts the records. Kentucky does not publish per-well production publicly, so that number is not available online at any price.

Alaska

Alaska Oil and Gas Conservation Commission

Alaska well records stay confidential for a statutory period after drilling and some remain so indefinitely, so a recent well may simply not be visible yet. Coordinates are published in NAD 27, and there is no interactive map viewer.

Which states charge for well data?

Only North Dakota, of the states on this page. Its well search, map, and statewide statistics are free, but per-well production, scout tickets, and well files require a subscription, $100 a year for basic access or $500 for premium as of January 2026. Texas is free to search and view but charges per page for copies out of its imaged records system. Everything else here costs nothing and requires no account.

Why does my state make this so hard?

Because these systems were built for operators and engineers filing paperwork, not for a retiree trying to understand a check. Three states split the job in a way that catches people out: in Kansas, West Virginia, and Kentucky the regulator issues permits but the university geological survey hosts the actual records, so searching the regulator's site leads nowhere. Several agencies have also been renamed recently, which is why old links fail. We keep this page current because we use these tools every day.

What if I still can't find it?

Send us what you have and we will look it up. A well name, an operator, a county, or a legal description is plenty, and often a photo of a check stub is enough. Ask through Ask a Landman or text 918-984-1645. It costs nothing, we do this all day, and we will tell you what we find whether or not you ever sell anything. If what you want is the operator's phone number rather than the well file, our operator directory is faster.

All links verified August 2026 and pointed at official state agency or state geological survey systems. State agencies reorganize their websites regularly; if a link here has gone stale, tell us and we will fix it. Berlin Royalties is not affiliated with any of these agencies.
