U.S. onshore oil and natural gas production is set to rise from October to November, propelled by supply growth in the Permian Basin and Haynesville Shale, according to updated projections Monday from the U.S. Energy Information Administration (EIA).

Natural gas production from seven key U.S. producing regions — the Anadarko, Appalachia and Permian basins, along with the Bakken, Eagle Ford, Haynesville and Niobrara shales — will grow by 257 MMcf/d from October to November to reach 87.9 Bcf/d, EIA said in its latest Drilling Productivity Report (DPR).

The Haynesville will see the largest month/month increase at 135 MMcf/d. Natural gas output is also expected to rise in the Permian (plus 78 MMcf/d), Appalachia (plus 41 MMcf/d), Niobrara (plus 19 MMcf/d), Eagle Ford (plus 14 MMcf/d) and Bakken (plus 8 MMcf/d) regions. The Anadarko will see natural gas production decline 38 MMcf/d to just over 6 Bcf/d in November, the DPR data show.

Total oil production from the seven regions will rise 77,000 b/d from October to November to reach 8.2 million b/d, according to EIA. Primarily driving this increase will be the Permian, which is set to raise output by 62,000 b/d from October to November. The Niobrara will contribute an 8,000 b/d increase for the period, while the Bakken will see production growth of 6,000 b/d, DPR data show.

EIA’s drilled but uncompleted (DUC) well count indicates producers across the Lower 48 drew down their backlogs from August to September, with overall DUC total for the seven regions falling 241 to 5,385. The Permian entered the period with the largest backlog and saw its DUC total decline the most month/month, drawing down 125 DUCs to end with 1,869 as of September. The Anadarko (down 16), Appalachia (down 16), Bakken (down 27), Eagle Ford (down 43), Haynesville (down 6) and Niobrara (down 8) also saw declining DUC totals from August to September, the DPR data show.

The recent DUC drawdown rate is unsustainable, analysts at Raymond James & Associates Inc. concluded in a report last month. 

In the “largest (and quickest) drawdown to date,” the current DUC inventory is crossing the critical “normal level,” analyst John Freeman said. “Over the last year, completions have outpaced new drills by nearly 250 wells/month, an unsustainable delta of which has never occurred.”

EIA’s DPR makes use of recent rig data along with drilling productivity estimates and estimated changes in production from existing wells to model changes in production from the seven regions.
