LONDON- Saudi Aramco has changed the type of crude loading onto a tanker due to go to Asia to Arab Heavy from Arab Light, a source familiar with the matter said.
The source said it was unclear what was behind the change.
Consultancy firm Energy Aspects said on Sunday that the quality of Arab Light and Arab Extra Light may have been affected by excess hydrogen sulphide.
