B015 Borehole characterisation of saturated unconsolidated sediments Summary 1 Seismic velocity and density of clastic sedimentary rocks usually increases with depth due to compaction and porosity reduction. In fully saturated environments Vp velocity trend is manly affected by water velocity and sediments compaction Vs velocity depends on quality of surface contact between matrix grain. Seismic measurements on 40 meters depth borehole were conducted according two different schemes: downhole with a single shots close to the borehole using a string four 3-component geophones (four geophones) and a walkaway VSP using a string of hydrophones. The main objective of the experiments was
