SAGD Program – Risk-based Well Integrity Management Phase 1: Field-scale Well Integrity Risk Assessment and Scoring System
A global oil & gas producer was developing a comprehensive subsurface containment and well integrity program for its oil sands operations, one of the most important oil sands in-situ developments in Alberta. The client wanted to better characterize cement and casing barrier failure mechanisms, root causes and develop a risk based well integrity risk scoring method for its SAGD production and injection wells. Oxand was selected to perform this assignment according to its unique Simeo Wellbase risk-based methodology.
The study delivered the following values to the client
- Comprehensive identification and ranking of key well integrity risks
- Risk based cement and casing barrier scoring system
- Risk based well integrity monitoring
