RE:RE:questionsIt is normal for BNK to sell for about 80% of Brent. That's why oil producers always show realized price. For example: COS Realizes full or more then WTI per barrel because they are selling light, sweet crude. The main reason for the price difference is the yield to the refinery ( the profit margin is like 21% for very heavy to 39% for a quality light). With that said, COS has a higher production cost, so they're not really making more per barrel.
