W.Africa Crude - Some offers rise on renewed supply worries

LONDON, July 31 (Reuters) - Some West African crude grades were being offered higher for September on Friday in the wake of renewed supply disruptions in the Middle East.

• Nigerian Qua Iboe for loading on September 6 to September 7 was offered at dated Brent plus $6.00, a trader said, up from recently heard levels.
• Despite the higher offer, two traders told Reuters this week that there remained a lot of unsold Nigerian cargoes.
• Gabonese Mandji for loading on August 13 to August 14 was also being offered on Friday.
• A number of tenders are pending, meaning some other cargo holders aren't offering into the market, the trader added.
