Schlumberger worked with numerous KOC personnel during the
implementation phase, including field development, production operations, gas
operations, system and policy, and IT teams. In close collaboration, allocation
networks were created for oil, gas, and water volumes collected from 26
gathering stations, connecting more than 3,000 wells.
The Avocet platform
allocates raw and sales figures on a daily and monthly basis using different
estimates including well tests, model-based, produced gas-oil ratios, and field
measurements. The allocated production volumes were used to generate official
monthly reports for KOC management and the Kuwait Ministry of Oil.
Customized dashboards were created for well test validation, which
allowed KOC to keep track of the percentage of validated well tests or reject a
test entirely. In addition, the well test validation screen summarized the main
well test events and highlighted changes in the expected results. Workflows
were also designed to validate wellhead pressure, flowline pressure, and water
New platform improves efficiency in generating production data
By integrating the Avocet platform with the KOC master database and gas
measurement database, official allocations were generated less than 7 days
after receiving the data from the gathering station.
The Avocet platform significantly improved the accuracy of the gas
allocation numbers, ensuring systematic quality assurance and quality control
processes for the data collection. Furthermore, daily collection and
aggregation of available high-frequency data tags from data historians were
automated, streamlining the process of moving data from the operational
database. As a result, this new process significantly enhanced data quality and
improved timeliness of data validation, approval, and reports.
Ongoing data collection process improvements are being planned by KOC.
By combining the Finder data management system and the Avocet platform, the
data workflow will enable KOC field operators and supervisors to capture,
verify, and report production data from wells and gathering stations more
efficiently. Where it is possible, the data will be collected automatically
from the KOC SCADA system, which includes meter readings, tank levels, and
equipment readings. Manually captured data will be entered directly into the
Avocet platform using a personal computer at the gathering stations or from a
mobile device in the field.
