US Cash Crude-Mars rises as WTI/Brent spread widens

HOUSTON, Feb 6 (Reuters) - Grades broadly fell on Friday, dealers said, although Mars bucked the trend to edge higher as the WTI/Brent spread widened.

The spread between WTI and Brent widened to a discount of as much as minus $4.75 during the session. A spread larger than minus $4 typically encourages export demand, driving prices higher.

U.S. oil production fell in November to the lowest since July, while oil demand fell to the lowest since April, data from the Energy Information Administration showed on Friday.

Crude oil output fell to 13.78 million barrels per day in November, down about 82,000 bpd from October's record high 13.86 million bpd, the EIA data showed.

U.S. oil refiners are expected to have about 1.3 million bpd of capacity offline in the week ending February 6, increasing available refining capacity by 90,000 bpd, research company IIR Energy said.

Offline capacity is expected to fall to 1.2 million bpd in the week ending February 13, IIR said.
