Drilled to a depth of 4,195 meters (13,843 feet) and penetrating some 75 meters of net pay, Cobalt said that, "while further appraisal drilling will be required to determine the ultimate size of the Lontra field, it is clear that Lontra is a discovery on a global scale”. Lontra is a pre-salt prospect off Angola in Block 20.

Therefore, when the a pipe section connecting the FPSO to the well ruptured (it´s still not clear at what depth the rupture occurred or even how many ruptures there were), there was nothing in them to spill out, avoiding what would have been the first serious pre-salt production accident resulting in a oil spill. It is also…
