The Snohvit PDO geo-model was compiled in 2001 ( ), with volumes and uncertainties described in
. A lot of effort has been put into a detailed Sto model, while the Tubaen Fm reservoir was originally modelled with only one layer, 100 m thick and with constant properties. An update of the reservoir model was madę in and consisted of a combined Sto Fm and Tubaen Fm model. The 2007 geomodel had initially
10 layers in Tubaen Fm. In 2009, another model was built ( ). The aim of this model was
to include seismic data from the new survey of the Askeladd Field, from improved imaging in the Snohvit gas-cloud area, and to get a better representation of the Tubaen Fm in the Snohvit field, as compared to the previous model. The focus was the CO; injection.
