Our customer operates five platforms which produce from 13 fields in the Central and Northern North Sea as well as a major pipeline system that transports approximately 10% of the UK’s oil production.
The customer uses the EnergySys production reporting system. However, as the fields in which the customer operates have evolved, so has the reporting system.
KELTON was engaged to audit and document the reporting system which had expanded since its initial configuration.
This involved understanding the source of the measurement data that fed into the reporting system, the details of all the required input data points and detailing all the calculations being carried out in the reporting systems.
With this information documented, the allocation system was replicated using spreadsheets and offline calculations to ensure that all required quantities are correctly calculated and any extraneous calculations were removed.
The customer now has a fully documented production reporting system which is representative of the actual hydrocarbon allocation.
