Numerical and experimental analysis of the porous medium reservoir at Pittsfield, Illinois
Numerical and experimental predictions of the St. Peter sandstone reservoir behavior at Pittsfield, Illinois, are being conducted. These analyses are based upon field and laboratory determinations of structural dimensions and physical properties and upon operating CAES design conditions. Numerical modeling addresses bubble development, water coning, thermal development and reservoir dehydration. Air injection rate is calculated as a function of time. The advance of the 50% saturation front during bubble development is depicted in depth versus radius curves for time periods up to 60 days. Experimental analysis embraces ground water chemistry, permeability and dehydration. Permeability of the St. Peter is highly variable due to vertical changes in lithology and variable friability. The new CAES porous media flow facility simulates field conditions of air flow rate, confining pressure, desaturation profile and dynamic stress.
