Understanding salt tectonics and salt geometry has always been important to petroleum exploration in the Gulf of Mexico (GOM). Initially, prospects were drilled almost exclusively above salt.Today, more and more prospects are being drilled beneath the upper layer of salt in the deep water. With the high cost of drilling, it is important to properly image the prospective sedimentary layers below salt.Seismic data acquisition and seismic data processing have improved dramatically over the years.In most cases in the deepwater GOM, seismic data can image the top of the allochthonous salt. In some cases, often after significant effort and cost, seismic data can also image the base of allochtho...
