O-26 COMPACTION MODEL FOR QUARTZOSE SANDSTONES. APPLICATION TO THE GARN FORMATION HALTENBANKEN MID- NORWEGIAN CONTINENTAL SHELF PART I – THEORY F. SCHNEIDER 1 and S. HAY 2 1 1 Institut Français du Pétrole 1 & 4 avenue de Bois-Préau 92506 Rueil-Malmaison France 2 Statoil Abstract The compaction of quartzose sandstones is described by a macroscopical visco-elasto-plastic model derived from microscopical considerations. This model considers that the reduction of total porosity is related to the variation of the relative cemented volume and to the variation of the relative intergrain volume. Furthermore we consider that the variations of these two petrophysical parameters
