Schlumberger has strengthened its well construction software portfolio with the acquisition of Wellbarrier—a small privately owned software company in Stavanger, Norway. The Wellbarrier® software offers a patented tool for well barrier illustrations and management based on the globally recognized two-barrier philosophy for well integrity, bringing additional capabilities in Schlumberger's well construction software solutions. Over time, the Wellbarrier software is expected to be extended to other offerings in the DELFI environment covering other well lifecycle activities beyond the DrillPlan solution. *** The Wellbarrier Illustration Tool produces well barrier schematics in a lean and user-friendly manner, helping engineers of all disciplines to create consistent well barrier illustrations in one common repository in minimal time to safeguard their wells and reduce risk. The software, which has been available since 2007, consists of: • Well construction data – well data. • Well illustrations. • Well barrier schematics. • Well schematics, which show well curvature. • Formation, pore, and fracture pressure curves. • Well control action diagrams. • Activity sequence diagrams. • Risk assessment and well ranking. • Completion diagrams and assembly drawings. It incorporates NORSOK D-010 Standard – Well integrity in drilling and well operations, and the two-barrier philosophy, ensuring that incidents do not escalate into accidents. More than 40 operators use the software, which has 60,000 well barrier descriptions, and is seen as the industry standard for well barrier drawings. To date, the tool has over 4,000 users in more than 45 countries worldwide. It applies to all well activities, covering the entire life cycle from drilling the different hole section through to the P&A of the wells.
