MOSCOW, Oct 6 (Reuters) - Urals crude differentials were steady again on Monday, after OPEC+'s planned production increase for November looked to be more modest than expected. OPEC+ will raise oil output from November by 137,000 barrels per day (bpd), it said on Sunday, opting for the same fairly modest monthly increase as in October amid persistent worries over a looming supply glut. Oil prices rose by about $1 on Monday, tempering some concerns about supply additions, though a soft outlook for demand is likely to cap near-term gains. The Kirishi oil refinery, one of Russia's largest, has halted a crude distillation unit, CDU-6, its most productive unit, following a drone attack and subsequent fire on October 4, with its recovery expected to take about a month, two industry sources said on Monday. There is enough supply of Russian oil for Indian refiners in the market as Ukraine's attacks on Russia's energy facilities have reduced its refining capacity and made more crude available, a government official told Reuters on Monday.
