CO 2 -EHR projects funded by Industry On-going. GEUS The laboratory is currently involved in various confidential projects funded by industry partners and related to CO 2 -EHR. The projects focus on several aspects such as recovery potential, chemical interactions, and caprock quality. 7 h CO 2 GeoNet Open Forum, April 17-19, 2012 Venice, San Servolo Island 6
CO 2 -EHR projects Dan Olsen, GEUS, and partners Chalk from the Tor and Ekofisk Formations of a Danish North Sea Core flooding experiments at the conditions of the reservoir. Both experiments started with a water-flooding, and then continued with a CO 2 -flooding. The Tor chalk produced 70.2 % OOIP during the water-flooding and 23.0 %OOIP during the CO 2 -flooding. The Ekofisk chalk produced 40.8 % OOIP during the water-flooding and 52.1 % OOIP during the CO 2 -flooding. The CO 2 saturation at the end of CO 2 -flooding was approximately 66% for both chalk types. Neither the Tor sample nor the Ekofisk sample showed evidence of dissolution after the experiments. Both samples remained within the elastic regime all through the experiments. A significant potential for CO 2 EHR is present in chalk, even after previously water-flooding. Ekofisk chalk that is non-economic for water-flooding may have potential for CO 2 EHR. 6 th CO 2 GeoNet Open Forum, May 9-11 2011 Venice, San Servolo Island 7

CO 2 -EHR related projects: Danish National Advanced Technology Foundation: Enhanced Oil Recovery through CO 2 utilization 2007-2010: The interplay between oil, water, CO 2, and chalk at reservoir conditions was studied based on sample material and data from the South Arne Field. The project is funded by the Danish National Advanced Technology Foundation and was carried out in collaboration between Department of Chemical Engineering at DTU, Institute of Environment and Resources at DTU, GEO, DONG Energy, and GEUS. Flooding experiments at reservoir conditions were carried out at GEUS. The experiments provided valuable information about the behaviour of a chalk reservoir during a CO 2 flooding operation, in particular regarding the timing and amount of oil recovery for both the Ekofisk and Tor Formations (Danish North Sea). 7 h CO 2 GeoNet Open Forum, April 17-19, 2012 Venice, San Servolo Island 10

What is allowed? CO2 geological storage allowed according to Subsoil Act, but the Minister/Parliament will not issue any license before 2020 Offshore, EHR possible, but unclear, can only be after debate in the Parliament In the governments energy strategy towards 2050 CCS is not an important component towards 2020. (March 15 th 2011) The government (May 12 th 2011) will not say no to CO2 storage, neither before 2020. That will prevent EOR to increase oil recovery and state revenue from the North Sea. At least onshore no storage Vattenfal refusal on Vedsted project (Oct. 14 th 2011) Small research projects most like not before 2020 The Directive ( 18) should not apply to projects with a total intended storage below 100 kilo tonnes, undertaken for research, development or testing of new products and processes. 6 th CO 2 GeoNet Open Forum, May 9-11 2011 Venice, San Servolo Island 12
