Method for providing reconciled estimates of three phase flow for individual wells and at individual locations in a hydrocarbon production process facility

摘要

A method for providing reconciled estimates of a process with three-phase fluid flow for individual wells and individual locations within a hydrocarbon production process facility with a plurality of wells, comprising the steps of a) using sensors to measure fluid flow data in the wells; b) measuring fluid data and equipment data in the hydrocarbon production facility; c) providing a rando in/ stochastic model for said measurements; d) providing a physics-based dynamic model of the process; e) configuring the dynamic model to support data reconciliation calculations; f) calculating estimated fluid flow for the individual wells and locations based on consistency between the measured fluid data and the dynamic model; g) calculating the expected accuracy of the estimated fluid flow for the individual wells and locations; h) calculating the expected accuracy of the dynamic model; i) calculating the discrepancies between the estimated fluid flow and the measure fluid flow and j) using the calculated discrepancies to identify and correct faulty measurements and calculate the reconciled production flows in the process facility.
