Maps showing offshore licence areas around the UK and shapefiles generated in GIS (Geographic Information System).
You can access a digital map of the UK Continental Shelf (UKCS) oil and gas activity by individual quadrant - (updated 04 July 2016) , showing the licensed areas, and below it pop-up detailed maps of each of the quadrants that contain licensed areas.
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 in the UK’s Territorial Sea and its designated Continental Shell (“the offshore area”). This includes those areas already under licence and those areas that are on offer in the OGA’s licensing Rounds.

The Crown Estate interests
The Crown Estate Agreements including Leases, Licences, Agreements for Lease and Search Areas (overlaying UKCS Petroleum Licensing Blocks)
This map is designed to assist petroleum licence holders to identify any area conflicts that their petroleum licences have with other users of the sea that have been granted rights by The Crown Estate.
Petroleum licence holders should identify any blocks where they hold a licence or plan to gain a licence to check whether there may be a potential area conflict with another rights holder. This could involve a physical overlap between a petroleum licence and a Crown Estate agreement or it could be a potential conflict if the areas are adjoining or in close proximity to each other (e.g. a helicopter zone may overlap with a Crown Estate lease).
Petroleum licence holders are strongly advised to contact the other rights holder(s) at the earliest opportunity to discuss and resolve any potential conflicts. In addition to this, if the licence sits within or partially within the 12 nautical mile territorial limit, licence holders must also contact The Crown Estate in order to be granted an agreement for seabed rights.
Further details are available on The Crown Estate web
Petroleum licence holders can contact The Crown Estate at email@example.com or on 020 7851 5343 with general or specific questions.
Oil and Gas Clause in Crown Estate leases
Under the terms of Crown Estate offshore renewable leases and agreements for lease, The Crown Estate may determine (i.e. terminate) the lease or agreement for lease in whole or part, following a request from the Secretary of State, for the purposes of allowing an oil or gas development to proceed. This is known as the “oil and gas clause”.
Where it emerges that the plans of an oil or gas developer and those of an offshore renewables developer may be in conflict, the parties are expected to make every reasonable effort to reach a commercial agreement at the earliest stage. The Secretary of State has made clear that he will only request that The Crown Estate determine a lease or agreement for lease after appropriate compensation has been paid by an oil or gas developer to the affected offshore renewable developer(s), or after a binding agreement has been entered with an oil or gas developer to pay such compensation. Read the Secretary of State’s Written Statement to Parliament.
Where the oil or gas developer and the offshore renewables developer are unable to reach a commercial agreement on compensation and the determination of the lease or agreement for lease is necessary for the oil or gas development to go ahead, the oil or gas developer can make an application to the Secretary of State to appoint an independent valuer to assess the appropriate level of compensation. Guidance on the procedure is available below.
Offshore GIS Data
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 John.Seabourn@oga.gsi.gov.uk
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’.
