well log data
well log data is downhole measurement curves recorded along a borehole, distributed as LAS and LIS files by NLOG, the Volve release and similar subsurface portals. In Datadory's catalog of 1,744 datasets, Equinor Volve Open Field Dataset and NLOG Netherlands Oil & Gas Portal are working examples.
What is well log data?
Downhole measurement curves recorded along a borehole, distributed as LAS and LIS files by NLOG, the Volve release and similar subsurface portals.
Some jurisdictions hold logs back under a confidentiality window — the Dutch portal releases them after five years.
In this catalog it appears concretely: - Equinor Volve Open Field Dataset — "LAS (well logs)". - NLOG Netherlands Oil & Gas Portal — "logs released after 5-year confidentiality". - Kaggle ROGII Wellbore Geology Prediction — "vertical typewell reference logs".
Why does well log data matter when choosing a dataset?
A label on a listing is not a deliverable. Teams that license on the strength of a product-name match routinely find the shipped files cover a narrower slice than they assumed, and backfilling history afterwards costs more than the license ever did.
The failure mode is concrete: the label appears in a listing, the delivered files tell a different story, and the gap surfaces mid-project when fixing it is most expensive.
You rarely have to take a vendor's word for it. 82.4% of the 1,744 datasets Datadory catalogs are free to access, and Equinor Volve Open Field Dataset lets you inspect the real artifact before any budget is committed.
How do you evaluate well log data in a data source?
Treat every claim of this attribute as testable:
- Open Equinor Volve Open Field Dataset and confirm its record — "LAS (well logs)" — against the files you actually receive.
- Open NLOG Netherlands Oil & Gas Portal and confirm its record — "logs released after 5-year confidentiality" — against the files you actually receive.
- Open Kaggle ROGII Wellbore Geology Prediction and confirm its record — "vertical typewell reference logs" — against the files you actually receive.

Frequently asked questions
What is an example of well log data?
Equinor Volve Open Field Dataset is the clearest example in this catalog. Its record states: "LAS (well logs)". Across all 1,744 datasets Datadory averages a quality score of 7.81 out of 10, so a named example can be weighed rather than trusted blindly.
Is data described as "well log data" free to use?
Treat access and permission separately. 82.4% of the 1,744 datasets in this catalog are free to access, but 235 are freemium and 61 are paid outright, so confirm both the price and the license on the exact distribution before building on it.
How do I verify a source really provides well log data?
Open Equinor Volve Open Field Dataset next to NLOG Netherlands Oil & Gas Portal and compare the promise with the download. Field definitions are verified for 1495 of 1,744 datasets (85.7%), which makes that check fast inside the catalog and manual outside it.
