In this work we have tried to explore the practicality of up-scaling laboratory velocity data to field measurements. This was done by conducting a series of laboratory measurements on samples from two shoreface facies sandstone hydrocarbon reservoirs from the North Sea. The acoustic measurements were conducted at room temperature and at confining pressures ranging from 5 MPa up to 45 MPa. The measurements were carried out on vacuum dry, brine- and oilsaturated samples. The ultrasonic data were compared with a sonic laboratory measurement and up-scaled to the wireline velocity data.
