proceduresystem and programmspeichervorrichtung to optimize ventileinstellungen in instrumentierten wells using adjungierter gradiententechnologie and reservoirsimulation

摘要

A new adjoint method for calculating and using adjoint gradients in a Reservoir Simulator comprises: calculating adjoint gradients of an objective function with respect to changes in valve settings taking into account the modeling of pressure drop and fluid flow along a wellbore, and using the adjoint gradients to calculate sensitivities of a reservoir to changes in parameterization of downhole devices and using of these sensitivities in optimal control of the wells to optimize some objective function subject to production constraints.
