Royal Dutch Shell Plc (RDSA) said oil that leaked from its 200,000 barrel-a-day Bonga field in Nigeria continues to thin.
Surveillance and aerial photos show the spill is breaking up into patches surrounded by clear water, Shell said in a statement on its website. The spill remains offshore. We continue to monitor its movement using satellite imagery and vessels in the zone.
Bonga, located 75 miles off Nigerias coastline, pumps about 10 percent of the West African nations oil.
