A report quoting unnamed four traders, has said that between 20 and 25 shipments of Nigerian crude for April loading are still floating on the high seas in Europe, searching for buyers.This development comes on the heels of another report that lingering strikes and protests in the French refining sector and seasonal maintenance at plants elsewhere in Europe cut into the OPEC producers sales.Observers say thats a much weaker position than normal for this time of the month when trade should be moving on to Mays barrels and the prices the shipments can fetch are dropping, they said.
