A MUltiple Space and Time scale approach for the quAntification of deep saliNe formations for CO2 storaGe

SOUTH SCANIA

SW Scania constitutes the marginal parts of a regional basin, i.e. the Danish Basin, which stretches across Denmark, SW Scania, NW Germany to the north of Poland.

The site area is bordered to the northeast against uplifted sedimentary strata and crystalline rocks by a large fault zone. The strata are, outside the faulted area, in SW Scania fairly horizontal with local anticline structures

Extensive seismic and drilling investigations of this site date from 1970s when the area was subject to oil and gas prospecting. Later on, during the 1980s, the strata with local anticline structures were subject to investigations concerning aquifer storage of natural gas. In the 1990s, rejuvenated interest in geothermal energy production resulted in drilling of two deep wells in the town of Malmö.

The thoroughly investigated wells are, however, today accessible for further investigations concerning aquifer properties and CO2 storage specific issues. In addition, deep wells in the site area of Southwest Scania these wells render excellent opportunities to evaluate the CO2 storage capacity in the area.
