Summary

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 ).
