Engineers managing underground gas storage projects are often faced with challenges involving gas migration, inventory variance, gas quality and inventory-pressures. This paper discusses a unique underground gas storage project where sales gas and ethane are stored in two different but communicating regions of the same reservoir. A commercially available reservoir simulator was used to model the fluid flow behaviour in this reservoir, hence, providing a tool for better management and use of the existing gas storage facilities.
