Lack or loss of integrity of the well/subsurface equipment
Lack or loss of integrity of subsurface equipment can be due to integrity failures due to poor cementation practices, mechanical damage during well development, corrosion and scaling, geo-mechanical disturbances, thermal stress and material failure or degradation, and aging over the life cycle of operations (drilling, work-over, exploitation, abandonment). It can also be due to equipment deficiencies.

Phases:
- Drilling / Testing
- Exploitation / Development
- Post-closure
-
Consequences:
- Economic / Performance / Acceptability
- Health / Safety / Environment
Mitigation
-
Prevention:
- Thorough cementing procedures -Thorough well design
- Perform adequate evaluation of corrosion and scaling potential
- Adapt the material selection to the chemical/physical properties of the fluid
- Temperature Maintenance
-
Monitoring:
- New sampling and chemical analyses
-
Corrective measures:
- Regular maintenance of the equipment, replacement or patch if needed
