Abstract

The advances in technology has resulted in significant gas production from the shale formations across the United States. Marcellus Shale which spans most of the Appalachian Basin is one the most prolific gas producers in the United States. Marcellus Shale gas has a distinctly different composition from the existing Northern Appalachian typical dry natural gas. As gas production from Marcellus shale has increased, so has the amount of the shale gas in the natural gas transportation system in the Appalachian Basin. The composition of the injected gas into a storage reservoir can the storage volumes, pressures, the withdrawal rate, and the pressure drawdown.;The objective of this study is to investigate the impact of storing Marcellus Shale gas on the capacity and deliverability of a gas storage reservoir. In this study, the working gas in the storage was assumed to be a mixture of the Marcellus Shale gas and the original pipeline (storage) gas. The fraction of the shale gas in the mixture was varied from 10 percent to 50 percent to determine the changes in the storage working volume, storage top pressure, withdrawal rate, and pressure drawdown. The results indicate that there is linear relationship between the fraction of the shale gas in the working gas and the changes in mixture storage working volume, storage top pressure, withdrawal rate, and pressure drawdown.
