SPE WA Lecture Series-Reservoir Performance of Disposed Carbon Dioxide in Saline Formations: Impact of Heterogeneity and Dip

Abstract:

Potential saline formation targets for carbon dioxide disposal must meet containment criteria for project success. In the selection process, detailed reservoir characterisation of these formations should be undertaken to understand the impact of formation heterogeneity on containment of injected carbon dioxide. A reservoir simulation study was conducted to evaluate the impact of varying net-to-gross, shale barrier length and formation dip on the subsurface behaviour of injected carbon dioxide in a hypothetical marine sand reservoir model. The study results showed that formation heterogeneity has a significant impact on the behaviour of the injected plume and can improve containment of injected carbon dioxide.
