Overview

This approach reveals hydrocarbon presence in the B annulus during plug and abandonment, enhancing safety.

Key Points

  • Advanced ultrasonic fluid characterization greatly reduces risks by accurately assessing annular contents.
  • Key fluid detection enables safe circulation before casing recovery, preventing potential platform shutdowns.
  • This approach employs pulse-echo and pitch-catch techniques in offshore plug and abandonment operations.
  • Results enhance operational efficiency by avoiding unnecessary mobilization of bleedoff packages in critical scenarios.
