Oklahoma well logs

Every time a well is drilled in Oklahoma, the driller files a completion report — the well log — with the Oklahoma Water Resources Board reported well logs. We hold 135,662 of them and rebuild this index weekly, so you can find one by address instead of by record number.

Find the well logs near an address

Well logs are filed by location, not by house number. Enter any Oklahoma address and we'll pull the recorded wells around it — Oklahoma records no street address for a well — location comes from the section description on the driller's log — so results show the wells around a location rather than a single wellhead.

What's in a Oklahoma well log

Not every filed report carries every field — older logs are thinner, and what the state captured changed over the decades. This is the actual coverage across all 135,662 records, so you know what to expect before you look anything up.

When Oklahoma's wells were drilled

Dated logs by decade of completion (133,240 of 135,662 records carry a usable completion date). The shape of this chart is mostly the history of the filing requirement, not of drilling — thin early decades mean the logs weren't kept, not that nobody drilled.

Three ways to find a well log here

  1. By address — the free lookup maps an address to the wells recorded around it. This is what most people want: "how deep is the well on the place I'm buying."
  2. By county — each county page carries the median depth, water level and yield computed from every log filed there, plus the drillers working it.

Where these records come from

All of it is public record from the well completion logs Oklahoma drillers file with the Water Resources Board (www.owrb.ok.gov). We don't hold anything the state doesn't publish. More on that database and what a filed record carries: OWRB well records. What we add is that the records are indexed by location, the statistics are computed the same way in every county, and the whole thing is refreshed weekly. Our filters and the exact computation are on the methodology page (statistics use OWRB reported well logs, water wells only (water-quality, monitoring, site-assessment and heat-exchange holes excluded); depths 0-5,000 ft. Water-level figures are OWRB's reported depth to first water).

Common questions

Are Oklahoma well logs public records?

Yes. Oklahoma drillers are required to file a completion report for each well, and those reports are kept by the Oklahoma Water Resources Board reported well logs. Anyone can look them up. This site is an independent index of that public record — we re-read the source and recompute every page weekly.

How do I find the well log for my property?

Well logs are filed by location, not by street address, so you search the map rather than a house number. Enter the address on our free lookup and you'll see the recorded wells around that spot — Oklahoma records no street address for a well — location comes from the section description on the driller's log — so results show the wells around a location rather than a single wellhead. Each one shows its depth, static water level, tested yield, and a link to the original filed log.

How far back do the records go?

The oldest dated log in our copy was completed in 1900; the newest is from 2026. Coverage thins out the further back you go — older wells were often never filed, and filing requirements tightened over time.

Why can't I find a log for my well?

Most likely it was never filed. Wells drilled before the state's reporting requirement — and hand-dug or unpermitted wells — have no log at all. It also happens that a log exists but its recorded location is off, in which case it will show up under a neighboring property. Neither is something we can fix from the source data, and we'd rather say so than invent a record.

What does a well log actually tell you?

The useful parts for a buyer or a homeowner: how deep the well is, how high the water stands in it, how many gallons per minute it produced when tested, what the driller hit on the way down, and who drilled it. Together those say whether the well is likely to keep producing and what a replacement would cost.

Need every log near one property, in one document?

The property report pulls every recorded well near an address — depths, water levels, yields, drillers , and links to each original filed log — as one printable summary for due diligence.
