Overview

Simulation study demonstrates a PTA method for detecting leakage in active and abandoned wells, suggesting improvements in containment monitoring workflows.

Key Points

  • Results indicate that PTA-based methods can accurately detect leakage events and estimate leakage rates for subsurface injections.
  • High accuracy was achieved for high-rate leakage events, while precision decreased for smaller rates, emphasizing the need for optimized detection methods.
  • The study utilized real-time pressure data from Permanent Downhole Gauges installed in wells to enhance monitoring capabilities.
  • The proposed methods serve as a cost-effective solution compared to traditional techniques like time-lapse seismic, applicable to various project sizes.
