Is Brent better quality than WTI ?

[James Regan + 1,776]

It’s seems to be the case that the lag price between Brent and WTI is growing shorter. Traditionally Brent carried a premium because it was considered a higher grade of Oil compared to WTI. Also the logistics and cost from wellhead to refineries added to the cost.

Is WTI now a blend of conventional and Shale oil?

Can we expect WTI to even out with Brent?

The 9/10 $ difference is slowly being eaten up.

I don't think it matters because they aren't competing grades.  That is to say they serve different markets entirely.  The reason for the disparity in price is that WTI is a local index and the excess supply here keeps the price down.
