Following months of steady increases, shale gas production across the nation might see a drop for the first time next month.

In its latest “Drilling Production Report,” the U.S. Energy Information Administration projected natural gas production across all seven major shale regions to decrease for the first time in September.

Production from these shale basins reached a high in May at 45.6 billion cubic feet per day, and is expected to decline to 44.9 Bcf/d in September.

In each region, production from new wells is not large enough to offset production declines from existing, legacy wells, EIA stated.

The Eagle Ford basin in Texas is projected to see the steepest decline in gas production between August and September, dropping by 112 million cubic feet/day. This loss is followed by the Marcellus Shale basin, which is projected to lose 60 million cubic feet/day during that period.

According to the data, the Utica Shale basin in eastern Ohio should see the least dramatic decline, with a loss of only 3 million cubic feet/day. The Utica region is also the only region included in the report that was expected to show production increases in June, July and August.
