Shale crude-oil production from seven major U.S. oil plays is expected to see a monthly climb of 79,000 barrels a day in October to 6.083 million barrels a day, according to a monthly report from the Energy Information Administration released Monday. The report has forecast increases in shale-oil output every month so far this year. Oil output from the Permian Basin, which covers parts of western Texas and southeastern New Mexico, is expected to see the largest climb among the big shale plays, with an increase of 55,000 barrels a day. Oil output at the Eagle Ford shale play in South Texas, however, is expected to decline by 9,000 barrels a day. October West Texas Intermediate oil clv7 was up 7 cents, or 0.2%, for the session at $49.96 a barrel, a few minutes before the settlement on the New York Mercantile Exchange.
