Figure 1.10. (a) Seismic lines and well paths in the vicinity of salt bodies in deepwater Gulf of
Mexico where the stress state around and within the salt bodies may have a significant affect on
drilling and wellbore stability (after Fredrich, Coblentz et al. 2003). (b) A seismic line in the
vicinity of two other salt bodies in the Gulf of Mexico. The presence of the salt is expected to
significantly deflect stress trajectories away from horizontal and vertical due to the fact that the salt
interface can support no shear stress.
