Overview

Simulation study demonstrates PTA methods enhance leakage detection in active and abandoned wells, implying cost-effective monitoring solutions.

Key Points

  • MAIN FINDING: The PTA methods effectively detect out-of-zone leakage, ensuring better monitoring of both active and abandoned wells.
  • KEY EVIDENCE: Results indicate high accuracy for detecting leakage rates, especially during high-rate events, using real-time pressure data.
  • APPROACH: This study employs a mechanistic well-reservoir model tested on a sandstone formation offshore Norway.
  • SIGNIFICANCE: The proposed technology provides a cost-effective alternative to time-lapse seismic methods for reservoir containment monitoring.
