  • The role of wireline, logging, and telemetry in well integrity assessment.
• Well Integrity Testing
  • Pressure tests: types, procedures, and interpretation of results.
  • Temperature, pressure, and flow rate measurements for detecting well integrity issues.
  • Conducting integrity tests during different stages of the well’s life cycle (completion, production, and abandonment).
• Advanced Diagnostic Methods
  • Acoustic and electromagnetic techniques for detecting casing defects.
  • Evaluating casing wear, corrosion, and mechanical failures.
  • Interpreting data from specialized tools like multi-finger caliper and acoustic logging.

Day 4: Managing Well Integrity Risks and Challenges

• Common Well Integrity Issues
  • Casing and tubing leaks: causes, detection, and prevention.
  • Corrosion, fatigue, and mechanical damage in cased holes.
  • Issues caused by cement failure or poor zonal isolation.
