UPDATE 1-U.S. shale oil output seen up for eighth month at 5.6 mln bpd -EIA

(Adds data throughout)

NEW YORK, July 17 (Reuters) - U.S. shale oil production is forecast to rise for the eighth consecutive month, climbing 112,000 barrels per day (bpd) to 5.585 million bpd in August, the U.S. Energy Department said in a report on Monday.

The increase comes amid market concerns that rising shale output will dampen the Organization of the Petroleum Exporting Countries' efforts to curb a global supply glut.

The U.S. shale production level would be the highest since record-keeping began in 2007, according to the EIA's monthly drilling productivity report.

The Permian Basin of Texas and New Mexico, the largest U.S. oil field, is expected to produce 2.535 million bpd, up 64,000 bpd from July, the U.S. Energy Information Administration said.

In Texas' Eagle Ford, oil production is forecast to rise 27,000 bpd to 1.387 million bpd, the most since February 2016. Meanwhile, in North Dakota's Bakken, oil output is set to rise by 3,500 bpd to 1.043 million bpd, the most since November, the forecast showed.
