Yes, the Crude Oil Futures we have on our website refer to the WTI Crude Oil.
Please see a brief explanation from Wikipedia:
"West Texas Intermediate (WTI), also known as Texas light sweet, is a grade of crude oil used as a benchmark in oil pricing. ... It is the underlying commodity of New York Mercantile Exchange's oil futures contracts. The price of WTI is often referenced in news reports on oil prices, alongside the price of Brent crude from the North Sea."
