Abstract: A method for controlling the influx of fluids into a multizone well in which each inflow zone is provided with an inflow control device, comprises: assessing the flux of oil, gas, water and other effluents from the well; monitoring production variables, including ICD position and/or fluid pressure in each inflow zone upstream of each ICD and/or downstream of each ICD; sequentially adjusting the position of each of the ICDs and assessing the flux of crude oil, natural gas and/or other well effluents; monitoring production variables; deriving a zonal production estimation model for each inflow zone of the well; and adjusting each ICD to control the influx of crude oil, natural gas and/or other effluents into each inflow zone on the basis of data derived from the zonal production estimation model for each inflow zone of the well.

Abstract: A method for describing one or more relations in a physical or other system on me oasis of an algebraic model of the system comprises the steps of: a) collecting data comprising measurements of different quantities relating to the system; b) interpreting the measurements of the different quantities as evaluations of different variables, which together comprise a polynomial ring; c) calculating an ideal of the ring, the generators of which substantially vanish on the collected data; d) interpreting the generators as polynomial relations between the variables of the system; e) reformulating at least one of the polynomial relations as an algebraic model for one of the variables in terms of the other variables involved in this relation; and f) the algebraic model is induced to generate one or more governing relations between parameters that govern the system using only measured data of the system.

Abstract: The present invention relates to a method and system for determining multiphase fluid streams flowing from individual wells of a cluster of crude oil, gas and/or other fluid production wells, wherein the fluid streams produced by the individual wells are commingled and routed via a fluid separation assembly into fluid outlet conduits for transportation of at least partly separated streams of crude oil, gas and/or other fluids.
