From this article, it seems that our Malaysian brand of Tapis crude was worth a lot lately:
The highest average price was observed on the Malaysian oil Tapis last week. Its average sport price hit $84.01 per barrel, which is less by $4.45 compared to the previous week. This type is used as a reference for the oil-producing zone of the Far East. Tapis’s density is 45.5-degrees API with a 0.1-percent sulfur content.
