LONDON, June 17 (Reuters) - Angolan crude exports are scheduled to be slightly higher in August, a loading programme issued on Monday showed, while some sellers of Nigerian crude offered cargoes at higher levels.
* The August programme includes 45 cargoes, one more than originally planned in July, a source said. The schedule from state oil firm Sonangol issued on Monday also showed 45 cargoes.
* About 8 cargoes of Angolan crude were still available from the July programme.
* About 25 cargoes of Nigerian crude were still available in July, fewer than the 30 estimated on Friday, a source said.
* Exxon is offering Qua Iboe for July loading at dated Brent plus $2.80 a barrel, a trader said. If a cargo traded at that level, it would be the highest differential since mid-2014, according to Refinitiv Eikon data.
* Uruguay’s ANCAP is running a tender closing June 18 for end-September delivery. (Reporting by Alex Lawler and Noah Browning; editing by David Evans) ))
