One of the Climate Change mitigation proposals suggested by the IPCC (Intergovernmental Panel on Climate Change) in its “Synthesis Report 2007” involves the launch of applications for capturing and storing carbon dioxide, existing three different geological structures suitable for gas storage: oil and gas depleted reservoirs, useless coal layers and deep saline structures.
In case of deep saline structures, the main problem to prepare a study of CO2 storage is the difficulty of obtaining geological data for some selected structure with characteristics that could be suitable for injection and gas storage.
According to this situation, the solution to analyze the feasibility of a storage project in a geological structure will need numerical simulation from a 3D terrain model. Numerical methods allow the simulation of the carbon dioxide filling in saline structures from a well, used to inject gas with a particular flow.
This paper presents a methodology to address the modeling and simulation process of CO2 injection into deep saline aquifers.
