HPHT fields in the North Sea account for a significant portion of UK total production. Expediting the successful exploitation of new HPHT structures in the UKCS can play a major role in maximising economic recovery and extending the asset life of existing infrastructure. While HPHT conditions are recorded in a number of UKCS basins, by far the largest resource attributable to HPHT producing fields, discoveries, and mature prospects lies within the Central Graben.

This pressure dataset, counting 194 wells, was generated from released well data in the NDR by Ikon Science. The dataset focusses on pressure data from the Jurassic and Triassic in the Central North Sea but also contains pressure data from Cretaceous intervals. The pressure data includes formation pressure and overpressure and is categorised by fluid type, test type/quality, and stratigraphy. Aquifer overpressure is derived for many wells, with an uncertainty range applied where hydrocarbon water contact or structural spill is uncertain. A pressure cell map interpreted on the basis of this dataset by the NSTA is published separately on the Open Data Site (Link to the interactive pressure cell map: https://www.arcgis.com/apps/webappviewer/index.html?id=cd62b9ec3b5644558aa12d37f354bab7 ).

As part of the NSTA’s published 2017/18 Activity Plan, the NSTA is publishing a set of regional geological maps for the Central North Sea and Moray Firth areas of the UKCS. These maps represent the first set of deliverables from a 3 year contract with Lloyd’s Register (LR) to produce a series of maps and associated databases for the whole of the UKCS. All data released with this set of geological maps is public domain data. The project has, however, benefited from a number of additional third party data sources which have been used to help inform final maps and/or derive interpreted products. These include the 21st Century Roadmap Palaeozoic project (which is now available in the public domain), PGS’s North Sea Digital Atlas, research data from the University of Aberdeen, CGG’s Target database and relevant products available via the BGS’s Offshore Geoindex. TGS are gratefully acknowledged for providing joined digital log data from LogLinePlus to enable the production of sand flag curves. Schlumberger, TGS and BP are acknowledged for providing additional seismic data to help QC interpretation carried out within the project and CDA are also kindly acknowledged for their support in downloading and providing much of the released well data to LR as part of this project. Due to the high level, regional nature of the project, the maps are being produced for the main geological time intervals e.g. Paleocene, Lower Cretaceous, Upper Jurassic. Each time interval includes the following products:

Depth structure maps Isochore maps Subcrop & supercrop maps Structural elements maps Depositional facies maps Reservoir distribution maps Source rock maps Well penetration maps Hydrocarbon occurrence maps

The products published here include:

a series of layered PDF documents which provide explanations of the various maps and datasets that have been produced plus a set of stratigraphic and petroleum systems charts. an ArcGIS project containing all of the maps and associated data. NSTA web feature services (WFSs) have been included in the map document in this delivery. They replace the use of a shapefile or feature class to represent block, licence and quadrant data. By using a WFS, the data is automatically updated when it becomes available via the NSTA digital copies of the sand flags (.las format) digital copies of the depth and thickness grids produced in the project (.xyz format)

We'd like to show you some of our most popular and newest maps.

NSTA Infrastructure Data is a set of data reported to the NSTA by relevant persons pursuant to Section 34 of the 2016 Energy Act. The data represents physical structures and facilities installed on the UKCS in fulfilment of relevant persons’ licence, field operations or pipeline works authorisation (PWA) related activities. The data is currently updated on a 6 monthly cycle (April / October). Data includes surface installations, subsea infrastructure, pipelines and pipeline freespans.Warning: Due to the 254 character limit of shapefile downloads, some attributes within this dataset will be truncated when downloading as a shapefile.

As part of the NSTA's published 2018/19 Activity Plan, the NSTA is publishing a set of regional geological maps for the SW Approaches area.

Southern North Sea Regional Geological Maps

Under the powers of the Energy Act 2016, detailed daily production data from individual wellbores must be reported to the NSTA, for the whole life of the field, as set out in the NSTA's Reporting and Disclosure of Information and Samples Guidance. The data is reportable when permanent cessation of production occurs. This requirement has been applied to all UKCS fields that have ceased production since January 2018. The apps below provide access and insights to this reported data. The data reflects the available production history of each field and provides an insight into daily values for gas, oil and H2O; as well as the pressures and temperatures at well heads and bottom holes, where available. The datasets can be downloaded by wellbore, hydrocarbon field or production hub.
