G019 ROCK PHYSICS TEMPLATES AND SEISMIC MODELLING OF CHALK RESERVOIRS IN THE SOUTH ARNE FIELD OF THE DANISH NORTH SEA LARS GOMMESEN 1 HANS PEDER HANSEN 1 JACOB MØRCH PEDERSEN 1 Abstract 1 Porosity fluid volume of clay and other factors such as degree of contact cement influence the elastic properties of the South Arne reservoir chalk. The aim of this study is both to describe the different effects and to introduce a fundamental workflow in order to perform a rock physics evaluation of the reservoir chalk. From the rock physics evaluation a rock physics model is created to generate
