Maps showing onshore licence areas around the UK and shapefiles generated in GIS (Geographic Information System).
Maps and Geographic data showing information relevant onshore licensing of the oil and gas industry. All our onshore maps and data is held and created using the British National Grid.
Current fields and licences wall map
This interactive map has been produced by the OGA to assist companies and members of the public with information that will help understand oil and gas exploration and production activity onshore in Great Britain including those areas already under licence and those areas that are on offer in the OGA’s licensing Rounds.
Onshore GIS data
Our data is provided in Shapefile and KML format. This allows our data to be used with a wide variety of software and applications. It is updated on a weekly basis.
We also offer a Web Feature Service (WFS) hosted with ESRI using their REST specification. If you would like more information about this please e-mail email@example.com.
To use the KML files copy and paste the link into your mapping software e.g. Google earth or if you’d prefer to download to your system right click and ‘save target as’.

Onshore licence coordinates are defined using the National Grid referencing system, which is a metric grid on a Transverse Mercator projection. National Grid coordinates are expressed as distances measured in metres east and north from the grid origin, which is located west of the Isles of Scilly. The National Grid defines a series of 100km by 100km squares, each of which is further subdivided into 10km by 10km squares. The 100km by 100km squares are identified by two letters, e.g. SE or TL. The 10km by 10km squares are identified by the letters of the 100km by 100km square within which they lie, plus a number from 00 to 99 as follows:
Example: If this diagram showed the SE block, then square 46 would be referred to as SE46.
The OGA refers to each 10km square as a block. A licence may cover a whole block, part of a block, or several blocks or part-blocks.

- the Ordnance Survey website offers further information on the For more information on the National Grid.
The system of quadrants and blocks used in offshore licensing does extend onshore, but we only use it for well numbering (see Petroleum Operations Notice 12 for details).
