Porous Underground Gas Storage Can Rapidly Provide Multiple Services to the Grid

This paper describes how ramp-up operations and commercialization of an underground storage asset were combined, rapidly providing a wide range of commercial services to the Italian gas system while long-term UGS performance increased continuously.

An underground gas storage (UGS) project has been developed from the Cornegliano depleted gas field in the Po Valley of Italy. The gas field was converted in December 2018. The complete paper describes how ramp-up operations and commercialization were combined in an optimal manner. These were conducted successfully in parallel with continuous development of the seasonal product and increasing flexible short-term activities. The authors write that diversified and increasing services can be provided to the Italian gas system with 100% reliability.

Field History and Description

The Cornegliano field consists of a typical anticline, bounded both to the north and to the south by reverse faults.
