Free Oklahoma Well Data: Where to Find It, What's Missing

April 15, 2026 · BasinBaron

If you operate in Oklahoma and you're not paying five figures a year for a subscription data service, you have probably already learned that the public data is mostly there — it's just scattered across half a dozen state and federal portals, each with its own login quirks, export limits, and file formats. This post is a plain-English tour of what's free, what each source actually covers, and where the gaps will cost you a morning if you don't know about them up front.

This is written for the independent operator, the one-truck saltwater hauler, the landman working a mineral deal on the side, and the small E&P shop that's trying to make smart decisions without a bloated data contract. If that's you, bookmark this page.

Oklahoma Corporation Commission (OCC) — the core of everything

The OCC is the state agency that regulates oil and gas in Oklahoma, which means they're the system of record for permits, well completions, operator filings, and Form 1000 / Form 1002 submissions. Almost every other free Oklahoma well dataset is derived from OCC filings, one way or another.

The OCC's OGW (Oil and Gas Well) records are the canonical source for well status, API number, spud date, operator of record, and location. You can pull well files individually from the OCC's imaging portal, and bulk well data is available through OCC's data exports, though the exports tend to lag a week or two behind the imaging system. If you need to confirm a well's status as of today, the imaging system is your source of truth.

The gotcha: location data on OCC filings is, historically, given as footages from a section corner (e.g., "330 FSL, 990 FWL of Section 12, T14N, R8W"). That's not a lat/long. You have to convert it, and the PLSS corners themselves aren't perfectly surveyed in every county. Expect 50–200 feet of slop on older wells and more than that on anything before 1980.

OKMap / Oklahoma Geological Survey (OGS)

OGS publishes a handful of well-curated GIS layers, including historical well locations with lat/long already resolved, and some basin-level structure and stratigraphy maps. The OGS well layer is particularly useful because it's already projected and de-duped against OCC — the conversion-from-footages work has been done for you.

OKMap, the state's GIS clearinghouse, is where you find county boundaries, PLSS sections, roads, and other reference layers you'll need to make a useful map. The data is all free, it's mostly shapefile or geodatabase, and the download speeds are honest.

NPMS — the only free pipeline source that matters

The National Pipeline Mapping System is the PHMSA-operated public portal for transmission pipelines. If you need to know where the interstate and intrastate gas and hazardous liquid transmission lines run, NPMS is the answer. The catch: NPMS only covers transmission and breakout tank farms. Gathering lines are not in NPMS. That's a big hole if you're trying to understand takeaway options for a new pad, because in unconventional plays, the gathering system is often the bottleneck, not the transmission line.

If someone tries to sell you a "free gathering line dataset for Oklahoma," be skeptical. There isn't one. Gathering line data comes from midstream operators themselves, or from paid data providers who have licensed it. We don't ship gathering lines on BasinBaron either — licensing that data costs more than our target customer pays for the whole product.

USGS and EIA — basin context

The USGS publishes formation maps, assessed resource estimates, and regional geologic framework data. For the Anadarko, the USGS assessment reports on the Woodford, Meramec, Mississippian, and Springer plays are free and worth reading if you want to understand where your acreage sits relative to the thick part of the pay zone. The data isn't granular enough to pick a drilling location, but it's more than enough to sanity-check what a broker is telling you.

EIA publishes monthly production by state and play-level DPRs (Drilling Productivity Reports) for the major basins. For Oklahoma, the relevant DPR is the Anadarko. Numbers are aggregated, so don't expect to see individual operator or well production — that's a paid product from the providers who license IHS / Enverus / TGS data.

What you can't get for free

Let's be direct about the gaps, so you can stop hunting:

• Monthly well-level production. Oklahoma is a non-disclosure state for production by well until the data ages out (and even then, good luck). If you see "free OK production data by well," it's either old or it's a preview.
• Decline curves / type curves. These are derived from well-level production, which is not free. We don't ship these in V1 for that reason.
• Well log images (raster) and LAS files. A small number are at OGS; most are behind paid log libraries.
• Gathering lines. Covered above. Not free, anywhere.
• Seismic. Different universe. Not a free dataset.

Stitching it together is the actual work

Each of these sources, on its own, is fine. The problem is that "free" in this context means "free if your time is worth zero." By the time you've downloaded OCC permit exports, joined them to OGS well locations, clipped NPMS to a buffer around your acreage, and dropped the whole thing into QGIS, you've spent three days of senior-engineer time that could have gone into actual deal work. And you'll need to do most of that again every month, because the data moves. For more on tracking offsetting activity in real time, see our guide to Anadarko Basin permit alerts.

The reason we built BasinBaron is that we got tired of doing exactly this for ourselves. The map stitches OCC, OGS, NPMS, and USGS together, refreshes nightly, and lets you filter, click, and export without a single shapefile touching your laptop. It's not a replacement for a five-figure data subscription — if you need monthly well-level production or decline curves, you're still buying that elsewhere — but for the 80% of day-to-day questions an independent asks, it's enough.

If you want to stay DIY, the sources above are the right starting point. Bookmark OCC, OGS, NPMS, USGS, and EIA. Learn to read PLSS footages. Get comfortable with shapefiles and QGIS. The data is genuinely there. It's just not assembled.
