Summary

As part of the wider Exploration strategy, the NSTA is publishing geological data to help promote exploration activity across the UKCS. One of the areas of data publication has been focused around improving the delivery of existing databases and as part of this, the NSTA is now publishing an updated version of the well tops database with a view to updating this twice a year.

All of the well picks provided are public domain data. The database has been compiled from the following providers and sources: the NSTA Regional Geological Maps project being carried out by Lloyds Register; Ternan Integrated North Sea and Atlantic Margin Reports; 21XCRM Palaeozoic Project; BGS database of composite log tops; and the BGS chronostratigraphy and lithostratigraphy databases (which are available as an Access database on the NSTA’s website - Well Stratigraphy Link).

A hierarchy, see below, has been applied to ensure that the most up to date picks have been selected for each well. The methodology employed looks for data from the highest priority provider and uses that where it is available for a well. If it is not available then data from the next priority source is taken and the process is repeated until there are picks available for a particular well. For example, Lloyds Register picks have been assigned the highest priority but if these are not available then Ternan picks will be used and if these are not available either then picks from the 21XCRM will be used.
