Solution:'West Texas Intermediate' (WTI) refers to a grade of crude oil. It is a specific grade of crude oil and one of the three major oil benchmarks used in trading, along with Brent and Dubai crude.Sourced primarily in inland Texas, WTI is one of the world's highest-quality oils. WTI is the underlying commodity for the NYMEX's oil futures contract. WTI is often compared to Brent crude, which is the benchmark for two-thirds of the world's oil contracts.
WTI is the main oil benchmark for North America, as it is sourced from the United States. It originates mainly in the Permian Basin, the site of the nation's highest-producing oil field. The oil travels via pipeline from Texas to refineries in the Midwest and the Gulf of Mexico
