SINGAPORE, Oct 3 (Reuters) -
* Australia's Woodside Petroleum WPL.AX has sold two October-loading cargoes of Vincent crude at premiums above $6 a barrel to dated Brent, two trade sources said on Thursday
* The two 550,000-barrel cargoes were offered to load over Oct. 8-12 and Oct. 17-18
* The buyers were not immediately known
* The spot premiums were much lower compared to other Australian heavy sweet crude grades - Van Gogh and Pyrenees - because Vincent just came back to the market after a long suspension and its quality needs to be tested, traders said
