Abstract

CO2sc is planned to be injected in 2013 at the Hontomín site (Spain) as a part of the EC-funded OXYCFB300 project. The objectives of this project are: the development of knowledge, methodologies and technologies for industrial application of geological storage of CO2; the demonstration that industrial activity is feasible and safe; provision of support to the regulatory authority; and the promotion of scientific and technological training in CCS. During the stages of selection and characterization activities have been conducted on structural geology, hydrogeology and hydrogeochemical, geophysics, laboratory experimentation and modeling of behavior and injection of CO2, natural gas emissions, and risk analysis. CO2 is going to be injected in a saline reservoir (1500 m depth) hosted by Lower Jurassic limestones and sealed by Lower Cretaceous clay formations. As part of the site characterization, baseline of CO2 flux in the soil-atmosphere interface has been determined. This is an important task to detect leakage in the reservoir during the operational stage and post-closure of the storage. In case of failure of the seal, CO2 fluxes in conduits such as wells or faults are expected to significantly increase, and they can be easily detected by comparing them with those from the pre-injection stage.
