COURSE OVERVIEW
This course is designed to provide participants with both fundamental and applied knowledge of Underground Gas Storage (UGS) systems. The program begins with an overview of gas reservoir engineering principles, followed by a review of global energy supply trends and the strategic role of natural gas. The concept of UGS as a peak-shaving and energy security solution is then introduced and discussed.
The course continues with a review of gas phase behavior, gas reservoir engineering fundamentals, and gas flow characteristics specific to UGS operations. Key topics include the application of the general material balance equation to UGS systems, reservoir fluid inventory analysis, and optimization of injection and withdrawal cycles.
In addition, the course addresses well pattern design for storage fields and the design considerations for surface facilities associated with UGS operations, providing participants with a comprehensive understanding of both subsurface and surface aspects of gas storage projects.
