Top Oil Expert: Geology is "Fractured" ... BP is Using a "Cloak of Silence", Refusing to Share Even Basic Data with the Government
The geology is fractured.
Usually, the deeper you drill, the more pressure it takes to fracture rock. This is called the "fracture gradient".
But when BP was drilling this well, the fracture gradient reversed. Indeed, BP lost all pressure as it drilled into the formation.
WB: Is it possible that this fractured, subsea salt geology will make it difficult to permanently kill the oil leak using relief wells?
Bea: Yes, it could. The Santa Barbara channel seeps are still leaking, decades after the oil well was supposedly capped. This well could keep leaking for years.
