Figure 1. Left: Seismic section across a faulted reservoir sequence. Note the lateral uncertainty in fault positioning and the horizon
uncertainty around the fault. The section is ~1000 m high. Right: Seismic-scale fault at outcrop (Suez). Note the minor faults, bed
rotations and shearing outboard from the main slip surface. In this case the true throw on the main slip surface is considerably less
than the bulk offset of the horizons across the fault zone (the component modelled by reservoir modelling packages).
