Real-time adaptive observer technology of an oil-well hydrodynamic deep states

This article is devoted to development of the well-bottom zone pressure real-time control method based on the adaptive supervision technology (Luenberger, 1971; Fang and Lozano, 1999). There are used as reliable and available devices for direct real-time control of the wellhead. Gas-lift and inflow parameters are linearized in the hydrodynamic model of the well.
