Having started operating these oil fields over a century ago, monitoring and control systems have evolved unrecognizably in that time frame. But so have data integrity issues. The number of records in the existing systems was vast (close to one million) and their data was not well-trusted by users.
- Capture: New tags had been added to field data capture systems without a process of recording why, leading to uncertainty over whether tags should remain in service long after they were in fact needed.
- Storage: There was no consistent tag naming approach across the regions leading to confusion and errors in consolidated reporting and feeding corporate business systems.
- Sharing: Having multiple disparate legacy field data capture systems made it very taxing and error-prone to evaluate problems or opportunities that crossed several regions.
