Case Study: Mitigating Tubing Failure & Sustained Annulus Pressure in a High-Pressure Gas Well Challenges

Here is a case study demonstrating how these approaches have delivered results in a specific field:

A client encountered repeated tubing leaks in a high-pressure gas well, along with uncontrolled annulus pressure buildup in the A-annulus (tubing-casing). These issues risked well integrity, compliance violations, and potential blowouts.

Tubing Stress Analysis

  • Conducted finite element analysis (FEA) to model tubing movement under thermal cycling (shut-in vs. flowing conditions).
  • Identified excessive compression buckling near the packer due to temperature-induced elongation.
  • Redesigned the tension/compression packer system and adjusted the tubing taper to mitigate stress concentrations.

Annulus Pressure Management

  • Diagnosed the source of A-annulus pressure (trapped gas migration vs. micro-annulus leakage).
  • Used thermal and pressure transient modeling to simulate fluid expansion and leakage paths.
  • Recommended a dual-action solution:
    • Installed an annulus pressure relief valve (APRV) for controlled bleed-off.
    • Applied nanopolymer sealant during cement remediation to eliminate micro-annuli.

Real-Time Monitoring & Verification

  • Deployed downhole gauges to track annulus pressure trends post-intervention.
  • Validated tubing integrity with multi-arm caliper logs after 6 months of production.

Results

Key Result Details
Zero tubing failures Over 2+ years of production.
Annulus pressure stabilized Within safe operating limits.
$8M saved By avoiding workovers and non-productive time (NPT).

Key Takeaways for Clients

  • Proactive modeling of tubing stresses prevents costly failures in thermal cycling wells.
  • Annulus pressure diagnostics must distinguish between thermal effects vs. true leaks.
  • Combining hardware + monitoring ensures long-term integrity.
