Public well atlas

Explore documented wells and boreholes. Search source identifiers, inspect coordinates and compare available records.

Partial source coverage. Status and company roles are reported by each source, not independently verified as current. Unknown does not mean zero.

Boreholes and sidetracks may share a well ID. Counts describe these source snapshots, not market size. Catalogue labels describe the source, not territorial boundaries. Permitted locations may not have been drilled.

YOUR FILTERED SELECTION

What can this selection tell us?

These summaries follow the same filters as the records below. Each number describes the available source records, not the global well population.

Data behind this view ↗

How much is reported?

A reported field is present, not necessarily accurate or current. Filtering on depth or date also changes the denominator.

What were these boreholes for?

Select a purpose to narrow the records. These classifications come from source descriptions; they do not establish current operations.

How deep are the reported boreholes?

Measured depth follows the borehole path. Each source has its own distribution and axis; reference levels remain unchanged. This is not vertical depth, and sources are not pooled.

The shaded box contains the middle half of reported depths, from the 25th to the 75th percentile. The line marks the median; whiskers show the observed minimum and maximum.

Completeness is not accuracy, reserve size, investment value or predictive skill. Borehole records, field production and nearby heat-flow sites have different scopes.

Plots and downloads use up to 64 original depth rows per source well, including the first and last. They are browsing samples, not the full training set. No interpolation is applied.

How to read the numbers
Median
Half the included values lie at or below this value, and half at or above. It is less sensitive to extreme values than an average.
Middle 50%
The shaded box contains the middle half of reported depths, from the 25th to the 75th percentile. The line marks the median; whiskers show the observed minimum and maximum.
Missing source cells
The source marked a value missing. It is not zero, and we do not fill it in.
source log wells
Source identifiers are not a cross-source count of unique physical wells. Log wells are not automatically joined to atlas boreholes.

Completeness is not accuracy, reserve size, investment value or predictive skill. Borehole records, field production and nearby heat-flow sites have different scopes.

Depth percentiles use linear interpolation (type 7) on finite, positive measured depths in metres, separately for each source and the selected records. The box is a descriptive spread, not a confidence interval.

Dataset library

Each dataset retains its source, access date, row count and reuse conditions. Filtered NDJSON is available for algorithm development.

Sources and methodology

Public administrative records are normalized with stable source identifiers. Original operators, drilling contractors and reported owners remain separate roles. Dates describe source access or reported events; they do not establish live activity. Coordinates are transformed to WGS84 where needed. Confidential records and personal owner fields are excluded. See each source for coverage, attribution and reuse terms.

NSTA data remains subject to source terms. The onshore agreement permits non-commercial use; the offshore layer has no item-level licence specified. Review each source before commercial use or redistribution.
