Well Integrity
Well Integrity Review for a European Gas Company Using Wellbooks
A European Gas Operator wanted to carry out a well integrity review on over 50 wells and meet local legislation requirements for documented wellbooks.
The operator was in the process of establishing a well integrity system, in line with local regulations. The wells were a mixture of active and inactive underground gas storage wells, legacy wells and shut-in wells.
SGS deployed a team of production technologists, subsurface geoscientists and well engineers to address:
- Integration of subsurface data
- Development of wellbooks
- Well integrity assessments
- Potential opportunities and concerns for each well
- Local legislation
SGS Solution
SGS successfully integrated and reviewed all subsurface data to complete:
- Wellbooks
- Structured subsurface archive
- Well integrity reviews
- Broader well reviews to identify opportunities and other concerns
The key steps in this project included:
- Reviewing and cleaning up data and information
- Carrying out a well integrity review with risk assessment, plus an integrated well review to identify additional opportunities
- Summarizing information into wellbooks
- Holding a meeting to carry out a reality check and confirm that final wellbooks meet legal requirements
