Context
• Maps are being produced at high level, regional scale
• Maps are produced for main geological time intervals – e.g. Upper
Jurassic
• All of the data that will be released with the maps is public domain
information
• The maps represent geological building blocks to carry out play
analysis

UKCS Geological Mapping Project - Devex 2017
Project Overview
• Three year duration
• Work will be done area by area
• Publication of maps on a rolling basis
• Central North Sea and Moray Firth maps almost ready
• Southern North Sea being worked on at the moment
• Data integration with neighbouring countries
• Publication at conferences
• Collaboration with academia
• Software: ArcGIS, Petrel, IPTM and ICTM

UKCS Geological Mapping Project - Devex 2017
• This project is the first to enable users to interactively use a wealth of
subsurface data and maps for the entire UKCS
• First data pack for Central North Sea and Moray Firth near completion
• Release of Southern North Sea maps late 2017
• Follow Lloyd’s Register’s LinkedIn Blog posts
