Abstract

Injecting CO2 into a subsurface formation causes a buildup of pressure in the vicinity of the injection well. While a large injection rate can reduce the cost associated with injection, an indefinitely large injection rate can result in excessive formation damage. To obtain an optimal injection rate without exceeding the safe pressure limits, one would like to have some knowledge of the transient pressure buildup characteristics resulting from a particular injection rate. Using some simplifying assumptions, we have developed an analytical solution to predict the transient buildup of pressure resulting from injection of supercritical carbon dioxide from a partially penetrating well into a gas reservoir. We use the analytical solution to study pressure transient characteristics for different formation permeabilities and anisotropy ratios.
