An Overview of CCS Road Map and Identification of a Suitable CO2 Disposal Site in Eastern Zagros (Fars Area) in Iran

Global warming and is a worldwide concern raised due to emissions of anthropogenic greenhouse gases. Oil & gas producing countries which are the members of the Kyoto Protocol, including Iran, have held a committee to reduce these gases, especially CO2 emissions. One way of reducing emissions is using carbon capture and storage technology in geological formations, known as Carbon Capture and Sequestration (CCS). Having a strategic roadmap to implement the CCS projects in Iran is essential. In addition, there is a close and direct relationship between the number of oil and gas reservoirs and amount of CO2 emissions in Zagros area in Iran. The objective of this paper is to present and discuss the CCS roadmap provided for Oil & Gas operations in Iran with focus on gas-industry related features. In addition, an appropriate geological structure in Zagros region suitable for CCS operation is proposed and discussed. The recognized aquifer at a depth of 1500 meters below the sea level in Fars area in Zagros, which is covered by Nar cap rock, maybe a good choice for CO2 injection. This aquifer is located in Lower-Dalan with appropriate reservoir property that is investigated in this paper. We will present the CCS roadmap in Iran, followed by the key features of CO2 disposal into this formation.
