Oil prices were holding steady on Tuesday after the week got off to a wobbly start, as a global crude glut remains an issue, especially amid signs of rising U.S. production. January West Texas Intermediate crude CLF8, -0.38% was off 4 cents to $57.44 a barrel, while Brent oil for February LCOG8, -0.26% gave up 8 cents to $62.37 a barrel. Oil prices settled lower Monday for the first time in three sessions, as recent data showing U.S. drillers added more oil rigs last week fed concerns over growing domestic crude production. WTI crude lost 1.5% to settle at $57.47, and Brent dropped 2% to end at $62.45 on Monday. The Organization of the Petroleum Exporting Countries decided last week to extend ongoing output curbs until the end of 2018, news that boosted prices Thursday and Friday. But U.S. supply issues continue to worry investors, with Friday’s rig numbers from Baker Hughes BHGE, +3.29% showing an increase in rigs actively drilling for oil in the U.S. U.S. supply data will swing back into focus on Wednesday with the release of data from the Energy Information Administration. Analysts polled by S&P Global Platts expect U.S. oil stockpiles to have fallen 4.1 million barrels last week and of gasoline to have risen 2.7 million amid increased refinery utilization rates. Elsewhere in the energy sector, gasoline for January RBF8, +0.14% was flat at $1.6913 a gallon, while heating oil for the same month HOF8, -0.36% also held steady at $1.893 a gallon. January natural gas NGF18, -0.64% slipped 3 cents, or 1%, to $2.955 per million British thermal units.via
