A PDE based model of artificial gas lift, its novel solution by the plastic bag algorithm and application in real-time simulator
A novel Plastic Bag algorithm is applied to the solution of the partial differential equations (PDE) describing the artificial gas lift (AGL) dynamics. The model is presented along with the oil and gas correlations used in the PDE model. Results of the solution, such as existence of oscillations in oil and gas flow and pressures in some operating modes, which reveals as a slugged flow, and absence of any oscillations in other operating modes, are discussed. An application of this model in a real-time simulator that is used in a hardware-in-the-loop setup is presented.
