Implement new PDMS
BreitBurn and Schlumberger collaborated on the installation and configuration of AVM software at several asset locations: Los Angeles basin and Orcutt field in the Santa Maria basin in California, Wind River and Big Horn basins in central Wyoming, and Sunniland trend in Florida.
The primary objective was for all the fields to use consistent data collection methods while still allowing the assets to specify parameters, such as data capture frequency (daily, weekly, monthly, or sporadic). The new software automated capture of the following production data types:
- products used in field operations
- well, meter, and other equipment readings
- preliminary shipment and sales
- tank inventories
- well tests
- equipment downtime
- screen comments
- meter calibration
- oil analysis
- handling of hot oil, load oil, and power fluid treatment chemical and electricity usage
- integration with SCADA systems for automatic data capture of cyclic injection steam activities.
Customized loaders were developed to migrate production data into the new system from BreitBurn’s legacy system and various Excel spreadsheets. An interface was established so users could also link to a third-party production analysis application. The monthly production allocations process was shifted to an AVM function for consistency with existing allocation workflows. A robust data validation process prevented erroneous data from entering the new system, avoiding the difficulties of correcting data at the volume allocations stage. A data validation wizard made it easy to set up warnings and not allow data processing to continue until errors were fixed. These validations are applied to manually captured data, as well as to SCADA-acquired data. If an item is missed by validation, it can be spotted in graphical or tabular views of the data-entry screen.
Steps were taken to maintain data synchronization, backup, and security:
1. configuration of field databases and replication from/to the master database at headquarters
2. configuration of security roles and user accounts with integration of Active Directory®.
The project delivered a complete reporting system, consisting of monthly production reports for state regulatory agencies; daily production reports using built-in AVM Grid Reports and Microsoft® SQL Server Reporting Services; reports and charts for well tests, well and field production, and injection history (including moving averages); and ad hoc reporting and charting capabilities.
Finally, operators and production accountants in all locations were trained on the new software to ensure understanding and productivity.
Support growing operations
BreitBurn now uses AVM software as a flexible PDMS that supports its
business needs. The automated system minimized manual intervention and the
number of validation points, significantly improving field data capture through
standardized processes and procedures. The management of production and related
operations data was optimized from collection and storage through the reporting
of monthly production numbers to regulatory state agencies.
The solution represents the next generation in production data
management—automating data processing calculations and quality control,
and providing audit trail mechanisms and workflows to support SOX requirements.
To date, 100 users have been trained, and the data for more than 2,000 active
wells, 700 facilities and equipment items, 35 pumper routes, and historical
data since 1900 have been uploaded. With this scalable platform, BreitBurn can
adapt the system as operations expand.
