Abstract

The use of geologic formations to store sequestered CO 2 offers the single largest capacity second to only oceanic sequestration. A material balance equation for CO 2 sequestration in gas reservoirs was developed to predict CO 2 sequestration volume and survey CO 2 sequestration operations during injection. Conventional gas material balance was adapted for CO 2 sequestration. With an established, linear trend from the production of gas from a hydrocarbon gas reservoir, a parallel line could be drawn to that reflects the predicted performance of the same reservoir with CO 2 instead of hydrocarbon gas. Evaluation of Z-factors for the injected gas, produced gas and reservoir gases is required if gas production continues during CO 2 injection, otherwise only injected and reservoir gas Z-factors are required. This is an abstract of a paper presented at the SPE Annual Technical Conference and Exhibition (Houston, TX 9/26-29/2004).
