Flare Solutions approach estimated to save Total Upstream Denmark several millions of euros in first eighteen months of acquisition.


In August 2017, Total SE acquired the Exploration & Production assets of Maersk Oil and became the second-largest operator in the North Sea. The data and information from Maersk included over 320 million files, amounting to 4 Petabyte of disk space.  From an early stage, Total Upstream Denmark (TUDK) engaged Flare Solutions to help with the integration effort.

Key Challenges

  • Deal with the influx of huge data sets; understand what exists and what to do with it
  • Maintain daily operations; minimise disruption and maintain minimised risk
  • Understand what vendor and seismic spec data Total were entitled to
  • Simplify the management of the information


Flare Solutions enabled several key outcomes for TUDK, including:

  • Improved Understanding - categorised 320 million files and process them appropriately, whilst maintaining ongoing operations for subsurface users.
  • TUDK has a dedicated search engine that can search over 320 million items in seconds. The enhanced tagging of key reports and data types has meant that search is also much more targeted.
  • Using the Folio application proved to be a cost-effective way to understand and manage the incoming data from this large acquisition.
  • There is a framework in place for building an effective information management system that will support current and future information needs.


Olivier Mairal, Head of Data Integration at Total, said “The scope in terms of the data we had to deal with, from the Maersk OG acquisition, was huge. The time constraint to digest and expose the full content in parallel of the running operations was not compatible with a standard data management approach so we had to find an innovative and efficient approach. Using Folio from Flare allowed us to not only index more than 320 million records in a few months but at the same time expose them to full user community that needed this information to maintain operations. The indexation, sorting and exposure was very efficient, and we managed to ‘connect' various sources such as Livelink, eSearch, and many disks from various regions into one single interface and search tool. The tool was also used to help data management activities during the clean-up exercise. In comparison and from parallel experience, a standard approach on a similar scope would have taken about 20 years to do this manually with one-person EFT and a significant saving in terms of budget. The transition project was a success and delivered on time. My team did a great job, and Flare Solutions' consultants and tools were also solid contributors to this success”.

Glenn Mansfield, Director at Flare, added, “We are delighted to have worked as part of the Total team to deliver this project, and we're very pleased with the successful outcome.  This illustrates the value of a knowledge-based semantic search system, enabling understanding of the content through automation, and delivering a solid foundation to support future integration and search developments.”
