Crude oil finished Friday with slight gains but losses for the week

Despite a small gain on Friday, crude oil prices still finished down for the week.

The reaction came after new sanctions were announced on Iran’s crude exports. Investors apparently are worried about President Trump’s trade war on China and more tariff threats against other countries.

West Texas Intermediate finished Friday up 39 cents or 0.55% at $71 a barrel on the New York Mercantile Exchange.

Global standard, Brent crude rose 37 cents or 0.5% at $74.66 a barrel.

Natural gas fell 2.76% or 9 cents to settle at $3.31.

Friday’s trading saw nearly all of the Oklahoma energy stocks with losses for the day. Mammoth Energy dropped more than 5% and 3% decreases were recorded by Empire Petroleum and Helmerich & Payne.
