A numerical analysis of supercritical CO2 injection into geological formations

One of the most promising means of reducing carbon contents in the ambience and tackling the global warming threat is injecting carbon dioxide into deep saline aquifers (DSAs). Selecting a site to store CO2 depends on many controlling parameters including permeability, heterogeneity, hydrostatic conditions, injection scenarios and domain grid resolution. In this research study, we aim to investigate the influence of different injection scenarios and flow conditions on the storage capacity and efficiency of CO2 in geological formations. This is carried out through a series of numerical simulations employed on 3-D hypothetical homogeneous and heterogeneous aquifers utilizing STOMP-CO2 simulation code. The results of this work are expected to play a key role in providing insight knowledge for assessing the feasibility of various geological formations for CO2 storage.
