US Cash Crude — Sour grades slip as OPEC+ producers ramp up oil output

(Updates prices ) HOUSTON, Oct 13 (Reuters) — Sour grades fell on Tuesday, dealers said, as OPEC+ oil producers raised output by an additional 900,000 bpd in September compared with August. Oil producer group OPEC+ posted a sharp gain in production in September, OPEC said on Tuesday, driven by an increase from Saudi Arabia despite ongoing disruptions to shipments through the Strait of Hormuz caused by the Iran war. OPEC+, which includes the Organization of the Petroleum Exporting Countries and allies such as Russia, pumped an average of 39.07 million barrels per day in September, OPEC said in a monthly report, up about 900,000 bpd from August. US crude oil stocks in the Strategic Petroleum Reserve were unchanged at 283 million barrels last week, holding at their lowest level since 1982, according to data from the Department of Energy. The recent drawdowns have been part of a US agreement to release 172 million barrels from the facility. The Phillips 66 355,000-barrel-per-day Wood River refinery in Illinois had issues with one of its catalytic cracker units and was shut down, two sources said.
