Underground gas storage in the old reservoir

When the oil field is almost depleted, there is possibility of using it as underground gas storage. In Republic oc Croatia some almost depleted reservoirs as in oil-field Žutica could be suitable as underground gas storage. For those reasons, the simulation of gas storage process has been performed. Acording to results of case study, during the first years of gas storage, enrichment of dry gas with valuable components can be expected.
