Figure 8. Seismic Line C-C’ shows the important strike relationships of fairways and deep salt highs. Green Canyon 18 field pay sands are in a younger Pleistocene fairway above a buried salt sheet. However, two older Plio-Miocene fairways flank either side of this younger fairway. The western fairway is the key to sand deposition at Mahogany, and can be traced updip under the salt sheet.
