High Collapse pressure (or external pressure beyond standards) are typical of critical wells due to depth, formation or temperature (Annulus Pressure build-up). For decades, Vallourec has developed process controls and collapse models backed-up by thousands of test results to deliver high collapse ratings for best-in-class performances.
- Casing strings exposed to high external pressure coming from formation, depth or temperature.
- Deep offshore and HPHT wells exposing casing to critical combined loads.
- Salt dome wells where shear stress can lead to very high local loads.
- Deep wells or deviated wells sensitive to casing wear.
