P07 WETTABILITY EFFECTS ON CYCLIC WATERFLOODING – EXPERIMENTAL SANDPACK STUDY Abstract 1 Cyclic waterflooding is an alternative process for optimised oil production. It has been successfully applied in some sandstone and carbonate formations with reports of additional oil recovery between 2 and 15% over conventional continuous waterflooding. In this work we present results from an experimental study performed on sandpacks of selected wettability conditions. A set of samples with a wide range of wetting affinities ranging from water wet to oil wet were prepared by appropriate packing of oil and water wet sand grains. Continuous and cyclic waterflooding runs were
