Shell denies that any of the oil is from its 200,000 barrel per day Bonga facility, 120 km offshore and accounting for 10 percent of monthly oil flows, which was shut down by the spill on Dec. 20.

Shell says five ships were used to disperse and contain the spill and that this kept any oil from washing ashore.
But local villagers, as well as environmental and rights groups, dispute this account, saying the oil is still at large, coating parts of the coast, killing fish and sparking protests.
