A METHOD AND A SYSTEM FOR FEEDBACK CONTROL OR MONITORING OF AN OIL OR GAS PRODUCTION SYSTEM AND COMPUTER PROGRAM PRODUCT

摘要

A method for automatic feedback control and/or monitoring of an oil and/or gas production system, or part(s) thereof, which includes one or more processing unit(s) and/or one or more flow line(s) and/or one or more control means. The method includes the step of: - measuring or estimating value(s) of at least one level or pressure or flow rate or load indicator associated with at least one of said processing unit(s) and/or flow line(s), and at least one of the following steps: - calculating setting(s), i.e. value(s) of associated set point(s), for said control means based on at least one controlled variable in form of said measured or estimated level or pressure or flow rate or load indicator, including compensating for nonlinearities of said control means, preferably by using at least one control module, - estimating at least one of the oil-, gas-, water-, or liquid flow rate(s) into and/or out of at least one of said processing units and/or flow line(s), preferably by using an estimator module.
