Geologist Roberto Fainstein, whose seismic imaging work at oil-field services company Schlumberger helped Brazil to discover its massive new reserves, says the subsalt find will "lead to a rush in this kind of drilling worldwide." Brazil's discovery may quicken subsalt drilling in the Gulf of Mexico by oil majors and Mexico's state-run oil giant Pemex. A salt layer offshore West African countries including Angola, Gabon, and Equatorial Guinea is "virtually identical to Brazil's," Fainstein says, "so companies will race to begin drilling it."
Avoiding the "Oil Curse"
Subsea salt layers are present in all three of the world's biggest offshore oil areas: the Gulf of Mexico, West Africa, and Brazil. So far, subsalt oil production has been executed only in the Gulf of Mexico, near the Texas and Louisiana coast where companies including BP, Shell, ExxonMobil, Chevron, and Anadarko Petroleum (APC) have all made significant discoveries.
