Magnetics can be quite useful in interpreting existing seismic programs after they have been shot. In [[:file:using-magnetics-in-petroleum-exploration_fig14-14.png|Figure 3]], two 2-D seismic lines have been placed purposely in the worst possible positions relative to the basement fault block pattern. | Magnetics can be quite useful in interpreting existing seismic programs after they have been shot.
