COURSE OVERVIEW

This course is designed to provide the audience with the basic and applied features of underground gas storage (UGS). The course starts with an overview of gas reservoir engineering, followed by a review of the outlook in energy supply worldwide. Then, the concept of UGS as a method of peak shaving is presented and discussed. Next, the gas fluid phase behavior, as well as gas reservoir engineering and gas fluid flow features of UGS is reviewed. General material balance equation applied for UGS and reservoir fluid inventory analysis in UGS, optimum design of injection/withdrawal cycles, and well pattern in UGS and design of surface facilities for UGS will be discussed in this course.
