Underground Gas Storage Process Optimisation with Respect to Reservoir Parameters and Production Equipment

The storage of natural gas in geological structures such as depleted fields, aquifers and salt caverns plays an important role a supply system it balances the fluctuation demand price. Hydraulic loss due to fluid flow through production equipment interfering effect from nonequal productivity index wells may have influence on performance. An integrated mathematical model is developed based underground facility data. Using this model, hydraulic determined. A real test case that consists reservoir linked surface analysed. uses experimentally determined pressure drop coefficient chokes. base scenario created using data enables achievement good history match with given parameters reservoir. simulation initial (a case), two different scenarios are determine injection withdrawal performance field. results indicate chokes, when fully open constraints facility, has significant impact operations deliverability.
