Uncertainty analysis field allocation Kristin-Tyrihans

Tyrihans and Kristin well streams are commingled in the production manifold topside and processed jointly in a semi-submersible processing facility installation (Kristin SEMI process plant). CMR has carried out an uncertainty analysis for the daily and monthly field allocation and field export of oil, gas and total hydrocarbon production from Kristin and Tyrihans.

Uncertainty analysis field allocation Kristin-Tyrihans

In addition to the uncertainty analysis, investigations have been made on how the output uncertainties are influenced by significant changes in production conditions.

A Monte Carlo statistical numerical analysis approach was used to ensure that all central aspects of the complex allocation model were included in the analysis. As part of the approach, uncertainty in important input variables was found based on historical data.
