In many [[Gulf of Mexico]] prospects, salt plays a key role in acting as a structural trap. Overhanging salt often forms seals, and sediments on salt flanks can have structural and stratigraphic pinch-outs against the salt. The exact shape of the salt is critical in understanding these traps. Unfortunately, seismic imaging often tends to be poor in these prospects. In [[:file:applying-gravity-in-petroleum-exploration_fig15-13.png|Figure 2's]] synthetic model (taken from a real structure), if a [[borehole gravity]] log were run, it would be able to tell conclusively which of the two [[seismic interpretation]]s shown below in the figure was valid. Either interpretation would have a significant impact on the completion and economics of the exploration play.  [[:file:applying-gravity-in-petroleum-exploration_fig15-13.png|Figure 2(A)]] is predicted BHGM logs through a salt body in the Gulf of Mexico, [[:file:applying-gravity-in-petroleum-exploration_fig15-13.png|2(B)]] is a model of the salt body, and  [[:file:applying-gravity-in-petroleum-exploration_fig15-13.png|2(C)]] is a seismic section through the salt body shown in the model (B).
