Chevron claims full responsibility for the disaster that occurred almost 2 weeks ago and has made assurances
that the underwater rupture had been sealed although there continued to be residual oil leaking from undersea rock at the Frade Oil Project.
The international environmental group Skytruth
suggested the spill was 10 times larger than the official estimate and backed up its claim with satellite images.
The cause of the spill was put down to
underestimated pressure of underwater oil deposits while drilling, causing oil to rush up the bore hole and seep into the surrounding seabed.
Meanwhile, Head of the Federal Police Environmental Division Fabio Scliar voiced concern about the methods Chevron was using to clean up the spill. He said, Chevron was "pushing" the oil to the bottom of the sea, thereby putting corals in the area at risk of destruction.
Currently the oil slick originating from the drilling location has extended over 2,379 square kilometers but is dispersing in a clockwise eddy by the ocean currents as it drifts further out to sea.
