Here is an assay of West Texas Intermediate, one of the world's market crudes. The price of this crude, known as WTI, is followed by market analysts, investors, traders, and industry managers around the world.

WTI price is used as a benchmark for pricing all other U.S. crude oils. The 410 API, 0.34 wt % sulfur crude is gathered in West Texas and moved to Cushing, Okla., for distribution.

The WTI posted price is the price paid for the crude at the wellhead in West Texas and is the true benchmark on which other U.S. crudes are priced. The spot price is the negotiated price for short-term trades of the crude. And the New York Mercantile Exchange, or Nymex price is a futures price for barrels delivered at Cushing.
