U.S. oil output from seven major shale formations is expected to decline by about 68,000 bbl/d in October to 7.64 million bbl/d, the U.S. Energy Information Administration (EIA) said in its monthly productivity report on Sept. 14.
That would be the first decline in production since May, according to revised data from the agency.
Output at every formation is expected to fall in October, except the Permian Basin of Texas and New Mexico, where production is expected to rise by about 23,000 bbl/d to 4.17 million bbl/d, the data showed. That would be the smallest increase since production declined in May, the data showed.
The biggest decline is expected to come from the Eagle Ford basin in South Texas, where output is expected to fall by nearly 28,000 bbl/d to 1.13 million bbl/d.
U.S. oil prices are still down about 40% from the peak at the start of the year, due to coronavirus demand destruction.
However, U.S. crude futures have gained almost 100% over the past five months to around $37/bbl, mostly on hopes global economies and energy demand will snap back as governments lift lockdowns.
Analysts said those higher oil prices have encouraged some energy firms to start adding rigs, an early indicator of future output, in recent weeks.
Separately, the EIA projected U.S. natural gas output would decline for a second month in a row to 80.6 Bcf/d in October.
That would be down over 400 MMcf/d from its forecast for September. Output from the big shale fields hit a monthly all-time high of 86.8 Bcf/d in November.
Output in Appalachia, the biggest U.S. shale gas formation, was set to slip for a third month in a row in October to 32.8 Bcf/d, down about 200 MMcf/d from September.
Pin Oak Energy Partners tacked on nearly 10,000 net acres to its Utica Shale position in the Appalachian Basin as part of a recent acquisition from EnCap-backed Protégé Energy.
Callon Petroleum and Carrizo Oil & Gas said Dec. 20 that shareholders from both companies voted to approve its pending merger, which had initially faced shareholder opposition.
