National Data Repository (NDR)

The United Kingdom’s National Data Repository for UKCS information and samples (NDR) is a key piece of UK digital infrastructure.

All offshore petroleum licensees and owners / operators of offshore infrastructure have access to the NDR to facilitate their reporting obligations to the NSTA. The NSTA may use the NDR to disclose reported information to any registered user, subject to statutory confidentiality periods.

Anyone with an interest in petroleum-related information may register to search, view and download disclosed information, free of charge, or to order data for delivery on media, on a cost reflective basis.

The NDR is available here:

The purpose of the NDR

The NDR addresses many industry and regulatory needs – including:

  • Ensuring global access to unique and irreplaceable petroleum-related information
  • Enabling the retention and reporting obligations of relevant persons to be discharged
  • Enabling the disclosure of petroleum-related information by the NSTA
  • Ensuring that maximum value is derived from petroleum-related information by ensuring the widest possible transparent access
  • Ensuring the sustainable curation of petroleum-related information and samples
  • In future applying the above principles to other data which the NSTA may hold or disclose in fulfilment of the NSTA strategy supporting the energy transition.

By ensuring that industry, academia and the wider public have ready access to timely and transparent data the NSTA is creating the conditions for the investment and innovation necessary to Maximise Economic Recovery and to enable the Energy Transition.

The new NSTA NDR - July 2021

The NSTA replaced the first iteration of the NDR on 1st July 2021 and the new version will be open to public access at the end of July 2021.The new NDR is based on innovative technology deployed by the NSTA’s partners Osokey Limited and brings new capabilities to NDR users, including data visualisation via the browser, advanced data compression and hugely improved download workflows, removing previously restrictive workflows.

The new NDR is delivered by a cloud-based solution, which can be scaled for what is expected to be a huge increase in the quantity of both post-stack and field geophysical data. Using its regulatory powers to ensure that geophysical and other data is reported the NSTA expects that an increase of about 4000% in the volume of data over the next 5 years. Importantly the NSTA has been working with Osokey to ensure that data reported to the NSTA is checked for compliance with NSTA “form and manner” reporting guidance before it is uploaded to the system by end-users. The energy transition and ensuring economic recovery both depend on quality data to support an understanding of the subsurface.

The new NDR is part of the NSTA’s Digital Energy Platform, and consumes services such as well headers from other NSTA systems including systems of record.

The NSTA intends where desirable to continuously enhance and improve the new NDR solution to best suit the needs of the widening user-base and serve new needs as part of the Energy Transition.

Personal Data

The NSTA has been asked on a number of occasions about how any personal data contained in information submitted to the NDR will be protected. The information reported to the NDR is being collected, and may be published, in the exercise of a function conferred on the NSTA by legislation. The NSTA does not require personal data to be provided in information. Relevant persons may, if they wish, remove any personal data from information before it is submitted to the NDR. If relevant persons have concerns that they are not compliant with data protection legislation in submitting information to the NDR, they should seek independent legal advice.

The NSTA’s policy on handling personal information is available here.
