March
On the 21st of March 2022, the Oil and Gas Authority changed its name to the North Sea Transition Authority. As a result, the GIS web services were altered to reflect the name change.
The previous ogauthority services to our data are to be turned off on the 15th April 2022.
Anyone who used the ogauthority API’s can use this look up table to find the updated services.
December
On the 13th of December we released new schemas and services for infrastructure data.
The previous infrastructure data included surface, subsea, pipelines and freespan locations.
It has now been expanded upon and restructured to include the below categories:
- Pipeline Points
- Pipeline Linear
- Pipeline Freespans
- Subsea Points
- Subsea Linear
- Surface Points
June
On 30th June, we added two new attributes to the licences service.
| Attribute | Alias |

| CUR_PHASE | Current Phase |
| CUR_TERM | Current Term |
On 24th June, we added new attributes to the wells service.
| Attribute | Alias |
|---|---|
| TDOPERATOR | Subarea Operator at TD |
| TDSAOPNUM | Subarea Operator at TD Number |
| TDOPPREV | Subarea Operator at TD |
| TDOPPREV | Subarea Operator at TD Previous Names |

May
On 26th May, we have added two attributes to the PPRS service.
| Attribute | Alias |
|---|---|
| GASINJCV | Gas Injected - CV (MJ/sm3) |
| GASINJVOL | Gas Injected - Volume (Ksm3) |
And two attributes were removed from the PPRS service. This is because the values were originally reported as volume (m3) rather than mass (kg) and inferring that volume equals mass may not always be accurate.
| Attribute | Alias |
|---|---|
| INJWATMASS | Injected Water - Mass (Kg) |
| WATPRODMAS | Produced Water - Mass (Kg) |
On the 3rd May, we made a schema change and supplemented the Licences service. For more information, please see here to see full details of the new schema.

July
On 5th July, we will add the attribute DEVIATTYP to well header downloads and services in all three coordinate reference systems.
June
- On 20th June, we will make a reformatted version of sub areas available. This version will have one record per equity group holder. It will be available to download via the Open Data site, and added as an extra layer in the NSTA_Licences_XXX web services in ED50, ETRS89, WGS84 and BNG coordinate systems. The existing sub areas dataset schema will remain unchanged.
- On 4th June, we will expand the NSTA_LicenceRelinquishments services and relinquished block downloads to include all relinquished licences for the UKCS. The service and download for these will continue to have links to the associated relinquishment reports. There are some schema changes associated with this change. See the new sheet ‘relinquishments’ here for more details
April
- On 16th April, we will switch off the GovSeismic services in the WGS84, ETRS89 and ED50 folders.
The same data is held in the NSTA_Government_Seismic folder under their respective CRS service. No data will be lost.
March
- Services domain change. On 27th March, our services will be using itportal.nstauthority.co.uk instead of itportal.decc.gov.uk. This will affect all our web mapping services.
- Well schema changes. See here for more details.
February
- Licence Schema Changes. See here for more details
- The web services: NSTA_Unsanctioned_Discoveries in all three coordinate systems and NSTA_Undeveloped_Discoveries_Montages in all three coordinate systems have been replaced by NSTA_Undeveloped_Discoveries in all three coordinate systems. This was a data rationalisation exercise, no information has been lost.
- The web services for 29th and 30th Round Indicative areas in all three coordinate systems have been replaced by NSTA_RoundIndicativeAreas in all three coordinate systems. The only difference between retired and current services is that we now include multiple indicative areas in one service. Indicative areas dating back to 29th round are included in this service and future indicative areas will be included here too. No information has been lost.
