Background and Objectives

  • Distributed fiber optic sensing (DFOS) is an emerging technology for real-time pipeline monitoring, specifically for leak detection and third party interference
  • ExxonMobil conducted a 90 day DFOS field trial on a West Texas pipeline with the following objectives:
  • Evaluate technical readiness of for future commercial applications
  • Assess performance in a real-world environment including accuracy, repeatability, false positives, and leak detection thresholds
