Simulator for a Natural Gas Storage Realised in Depleted Deposit

The present paper presents the implementation of a numerical model for a natural storage transformed into a deposit which takes into consideration the geometry of the storage, the properties of the rocks and in which the movements of the gases can be described. The model is two-dimensional nonstationary and allows the dynamic simulation of the processes of injection and extraction. The location of the wells and their flows can be thus studied and optimized to maximize the amount of the stored gases. The presented model allows the quick finding of solutions for a whole cycle of storage in a short time so that it could be used successfully in the operation process.
