U.S. shale oil production for September, which includes a new regional data input, is forecast to rise by 117,000 bbl/d to 6.15 MMbbl/d, its ninth consecutive monthly rise, the U.S. Energy Information Administration (EIA) said on Aug. 14.

The total forecast figure has expanded to include the Anadarko region, a growing and prolific shale play that has the second-most operating rigs, at 129, after the Permian’s 373, according to the EIA’s monthly drilling productivity report.

The EIA added that the region has become “the target of many producers using improved drilling and completion technology to this already well-established oil and gas producing basin.”

Meanwhile, the EIA is combining the Marcellus and Utica regions into a new Appalachia region to help the precision of its productivity estimates.

Without the addition, total shale output for September would have been forecast to rise by 106,000 bbl/d to 5.69 MMbbl/d.

In the Permian Basin, oil output is set to rise by 64,000 bbl/d to 2.6 MMbbl/d. In the Eagle Ford, oil output is forecast to rise by 14,000 bbl/d to 1.39 MMbbl/d.

In North Dakota’s Bakken, oil production is expected to rise by 10,000 bbl/d to 1.05 MMbbl/d.

New-well oil production per rig was expected to slide by 10 bbl/d to 645 bbl/d in September.

U.S. natural gas production was projected to rise to 59.2 Bcf/d in September.

Output in Appalachia was set to rise by 0.35 Bcf/d to 24.6 Bcf/d in September. Meanwhile, Haynesville output was set to rise by 0.15 Bcf/d to 6.9 Bcf/d.
