Crude futures ended higher on Friday as Hurricane Harvey threatened Gulf production, with about 25 percent of US Gulf offshore output shut in. WTI settled at $47.87 and Brent at $52.41, though crude still posted a fourth straight weekly loss.
Gulf of Mexico shut-ins tighten crude supply, but weak refinery demand limits the price gain, so energy costs for feed production remain volatile.
