Fig. 4. A regional east-west cross-section of the Jurassic succession from the top Statfjord Formation (orange surface at the
base) of the Tampen area (Gullfaks-Kvitebjørn); see Fig. 1 for location. The seismic section (in time) shows fault and
horizon interpretation (lower) with well tie. The section displays the general Triassic-Jurassic thinning from west to east.
An apparently isolated and several tens of metres thick sandstone unit occurs at the base of the Ness Formation (see well
34/10-23).
