when talk about the price of bitumen is that before they add the diluent?

Yes. For example:

In Q3 CLL sold their Bitumen by adding the diluent and selling it as a Dil-Bit with the average price of $95/bbl.

When you subtract the cost of diluent CLL average price of Bitumen in Q3 was $76/bbl.

PS. Sam , there is nothing wrong with asking the question. What the 2C was referring to is that if the question is not related to the threads (discussion) select the POST A NEW MESSAGE window and ask the question or start a new thread.

Also it would help if you read the answers to you question.

Remember, nobody is smart here. If we would be smart we would not be wasting our time here.
