Directive 2009/31/EC of the European Parliament and of the Council of 23 April 2009 on the geological storage of carbon dioxide and amending Council Directive 85/337/EEC, European Parliament and Council Directives 2000/60/EC, 2001/80/EC, 2004/35/EC, 2006/12/EC, 2008/1/EC and Regulation (EC) No 1013/2006 (Text with EEA relevance) · European Union

pressure and temperature of the storage formation as a function of injection rate and accumulative injection amount over time; areal and vertical extent of CO_(2) vs time; the nature of CO_(2) flow in the reservoir, including phase behaviour; CO_(2) trapping mechanisms and rates (including spill points and lateral and vertical seals); secondary containment systems in the overall storage complex; storage capacity and pressure gradients in the storage site; the risk of fracturing the storage formation(s) and caprock; the risk of CO_(2) entry into the caprock; the risk of leakage from the storage site (for example, through abandoned or inadequately sealed wells); the rate of migration (in open-ended reservoirs); fracture sealing rates; changes in formation(s) fluid chemistry and subsequent reactions (for example, pH change, mineral formation) and inclusion of reactive modelling to assess affects; displacement of formation fluids; increased seismicity and elevation at surface level.
