W. Africa Crude-Sagging demand keeps differentials weak

LONDON, June 30 (Reuters) - Nigerian crude oil cargoes
failed to attract much interest from buyers on Monday, traders
said, with expectations that differentials will fall further
keeping activity thin. 
    There were still around seven cargoes due to load in August
available on top of more than 50 for July, a trader said. 
    Slack demand from European refiners that have cut runs due
to lower margins has hit demand, while sharper drops in
differentials in crudes from other regions have limited demand
from Asia and elsewhere.
