Oil and Gas Industry Site Survey Project

The British Geological Survey (BGS) has been archiving oil and gas related survey activity metadata since 2009. This project collects top-level site survey metadata in the field of marine geology and geophysics. This is directed towards new oil and gas industry site surveys acquired under both exploration and production licenses by oil company licensees, but excludes borehole Vertical Seismic Profiles (VSP's).

Licensees are requested to provide information for those site surveys for which they are the Current Owner, where Current Owner means the company which is the current operator of the licence under which the survey was shot.

This project is done in collaboration with the Oil and Gas Authority (OGA) and benefits data providers and users by providing:

  • Free, long-term and secure storage of data
  • More efficient use of time and resources
  • Access to the best available seabed geology and shallow geological models
  • Ready access to data for new uses such as renewable energy technology, aggregate mining, Carbon Capture and Storage (CCS) and siting of other offshore infrastructure

BGS approach companies to provide their metadata; notification of new metadata will be through the Petroleum Operations Notices (PON) system. This applies to oil and gas industry surveys or shallow drilling activity in the UK, with particular emphasis on UK Continental Shelf (UKCS) seismic and site surveys. The metadata will be made available subject to any agreed restrictions and once any confidentiality period has expired.


The following information for each new site survey is required:

  1. Completed PON 14a survey closeout form                                                  
  2. Map showing survey area and boundary coordinates
  3. Completed MEDIN Site Survey Submission Form (this will be sent to the licensee on submission of the PON 14a survey closeout form)

Metadata Submission

Submissions are to be made using the MEDIN Site Survey Submission Form plus attachments as appropriate. A detailed specification of the data required in the form is described below.

Survey Header Metadata

Using the 1st worksheet (labelled Survey Metadata), please:

  1. Complete (Submitted by) and (Data Enquiries Contact Details); and then
  2. Complete survey details (one row per survey). Note, a number of attributes are mandatory, and we urge you to provide values for all other attributes if at all possible; and
  3. Refer to the Explanation of Column Headings section to complete the details required.

Survey Equipment Metadata

Using the 2nd worksheet (labelled Survey Equipment), please:

  1. Complete equipment type details (one row per equipment type); and
  2. Refer to the Explanation of Column Headings section to complete the details required.

Boundary Coordinates

Using the 3rd worksheet (labelled Boundary Coordinates), for each site survey please provide:

  1. Boundary Coordinates, by providing co-ordinates of the points defining a polygon of the survey area, including details of the Coordinate Reference System used; and
  2. Refer to the Explanation of Column Headings section to complete the details required.

Submission Address

For all new site surveys a completed MEDIN Site Survey Submission Form, map showing survey area and boundary coordinates and PON 14a survey closeout form should be emailed to MEDIN Data Management Team at BGS (medin@bgs.ac.uk).

Please note:

By sharing data we massively reduce duplication of effort between organisations - saving time and money.

All the metadata is freely available via the MEDIN portal together with the contact details of the data owners.

Access to this data is important, and benefits the industry stakeholders who submitting it, as well as the scientific sector. Combined, this data allows scientists to produce more reliable models, so that they can work out how the working environment is changing. The data we are asking for play an important part in the process of making sound, scientific decisions on where to work for maximum results.


  • Technical queries on data submission and completed submission forms should be directed to the MEDIN Data Management Team at BGS.
  • Queries on the PON 14a regulation and survey closeout form should be directed to the OGA Head of Technical Data Phil Harrison.
