Using underground gas storage to replace the swing capacity of the giant natural gas field of Groningen in the Netherlands. A reservoir performance feasibility study.

摘要: In this study we probe the ultimate potential Underground Gas Storage (UGS) capacity of Netherlands by carrying out a detailed feasibility on inflow performances all onshore natura! gas reservoirs. The is one largest producers in Western Europe. current decline its national production and looming restrictions field Groningen -owing to induced seismicity- have recently made necessary upgrade two UGS Norg Grijps-kerk. joined working volume these expected replace swing continue guaranteeing security supply low calorific gas. question whether configuration will provide storage unrestricted issues reservoir and/or seismicity. This matter be paramount im-portance near future when advance state depletion turn into net importer high natural By then, available UGSs still economically attractive operating, or if additional alternative needed?. Hence characterization ranking best reservoirs today importance for developments.
