Current Crude Oil Price

I am trying to find a website that I can access all day to find the current price of a barrel of crude oil. This would be for the region of the Williston Basin in Montana.

Seeing how the oil basin varies from 27 ° to 48 ° API I do not think you will find a unique number.

In general, producers have contracts with the refineries which they sell, by specifying a range of quality of their products (largely based on the viscosity and API sulfur content) and price (usually a percentage of oil reference). For example, you could be paid 80% of the price of West Texas Intermediate, or such a number.

If I were to guess, I would bet that the oils of the Williston Basin are sold under a variety of qualities and contracts. It is usually not too easy to get the exact conditions of these contracts from public sources.
