The world has been faced with the most serious environmental issues which is the global warming of the earth and this is due to the accumulation of greenhouse gases (GHG: H2O, CO2, N2O etc.) generated by human activities (fossil fuel combustion). Reducing man-made CO2 emission is a key element in mitigating greenhouse gas emission specially CO2. Among the different solutions for CO2 emission reduction such as energy management, use of renewable energies, forestation, the technologies of Carbon Capture and Storage (CCS) into the geological structures has high potential in mitigation of CO2 emissions from anthropogenic sources.

In this paper, after a brief introduction to CCS-EOR technology, the overall quantity of CO2 emission in Iran is introduced as a database. This involves different acid gas sources in petroleum industry and energy section and their high priorities.

Iran has many sour oil and gas reserves and Assalueh gas field is considered as one of the highest priority sources of CO2 in NIOC in terms of both amounts of emission and the possibility of CCS deployment. Carbon dioxide obtained from sweetening of natural gas is considered as a major CO2 source because of its low cost of capturing compare to the other sources.

According to this, assessment for a case study project is done in this field. Selecting optimal structures that match the CO2 underground storage criteria involve many factors like geological, geothermal and hydrodynamic conditions, emission source location, economic, legal issues etc.

Based on theses parameters, this paper investigates possibility of CO2 injection in 24 different geological structures in south of Iran
