Fiber Optic Monitoring Pinpoints Well Leaks Without Operational Disruption

Objectives

  • Acquire temperature anomalies and acoustic activities along the wellbore to detect potential leaks in the B annulus using distributed temperature sensing (DTS) and distributed acoustic sensing (DAS) technologies.

Our Approach

  • The B annulus was showing pressure increasing over the time and, since the fiber was already installed (October 2022), Weatherford experts recommended applying the DTS and DAS technology.
  • This non-intrusive solution required no additional wireline tools or site preparation and would not incur any downtime.

Value to Customer

  • The comprehensive insights delivered both qualitative and quantitative data on fluid dynamics, enabling accurate characterization of failure patterns in the well completion.
  • The analysis clearly located the well-integrity issue and confirmed flow behind the casing.
  • This approach not only resolved the immediate concern but also demonstrated the long-term value of permanent fiber optic installations for proactive well surveillance.
