Physical and chemical stability of Galesville Sandstone at elevated temperatures and pressures

PDF Version Also Available for Download.

Description

Galesville Sandstone is currently being considered as a candidate lithology for a Compressed Air Energy Storage (CAES) demonstration facility. This paper summarizes the results of a preliminary set of laboratory-scale autoclave experiments on a sample of the Galesville from the Media natural gas storage field in Illinois. The dependent variables of interest are percent changes in air permeability, liquid water permeability, and friability (disaggregation potential). The independent variables include temperature (50 to 300/sup 0/C), pressure (60 to 120 bars), time (0.5 to 2.0 months), oxygen content (0 to 21%), carbon dioxide content (0.0 to 0.1%), autoclave type, autoclave stirring frequency, ... continued below

Description

Galesville Sandstone is currently being considered as a candidate lithology for a Compressed Air Energy Storage (CAES) demonstration facility. This paper summarizes the results of a preliminary set of laboratory-scale autoclave experiments on a sample of the Galesville from the Media natural gas storage field in Illinois. The dependent variables of interest are percent changes in air permeability, liquid water permeability, and friability (disaggregation potential). The independent variables include temperature (50 to 300/sup 0/C), pressure (60 to 120 bars), time (0.5 to 2.0 months), oxygen content (0 to 21%), carbon dioxide content (0.0 to 0.1%), autoclave type, autoclave stirring frequency, and the humidity conditions. Three humidity conditions were simulated: (1) dry air only, (2) air and water vapor, and (3) liquid water only. Temperature, humidity and time were the dominant variables. Apparently, solutioning of silica and carbonate cements attributes markedly to the observed increases in friability and permeability for cores treated at elevated temperature in a liquid and/or vapor environment. The lack of confining pressure may also be a significant factor. The average change for air and liquid permeabilities was approximately 30 +- 10% for all conditions tested. The average increase in the friability index was 150%.
