Optimising Withdrawal and Injection Performance for Gas Storage Reservoirs

H-12 OPTIMISING WITHDRAWAL AND INJECTION PERFORMANCE FOR GAS STORAGE RESERVOIRS Abstract 1 The paper will present an integrated approach defined and implemented by ENI AGIP technical services and STOGIT SpA (the Italian gas storage company) for the optimisation and day-by-day operation of gas storage reservoirs. In the scope of the project reservoir simulation models and plant simulation models have been integrated to provide the complete picture for the selection of optimal operating points. Models are continuously and automatically updated with gas withdrawal/injection data and plant component availability and efficiency status. Optimisation techniques have been exploited to determine the best scheduling
