U.S. shale well productivity rates should keep ticking up in May although total production will fall by 57,000 barrels per day, according to a new report by the U.S. Energy Information Administration.

The report found that new-well oil production per rig in the seven largest U.S. shale plays will climb by an average of 13 barrels per day of oil and 122,000 cubic feet of gas per day next month.

Permian Basin oil wells are expected to pump an additional 25 bpd, bringing the play’s average new-well oil production to 265 bpd in May.

New-well gas production at the Texas play is projected to rise by 39,000 cubic feet per day.

The Eagle Ford play, also in Texas, will see new-well oil production per rig climb by 20 bpd while gas production will grow by 22,000 cubic feet per day.

Oil rigs at the prolific Bakken play will pump an additional 18 bpd while gas rigs at the play should add another 13,000 cubic feet per day of production.

New-well gas production at the Utica and Haynesville plays will see the largest gains in May with production leaping 132,000 cubic feet per day in Utica and 88,000 cubic feet per day in Haynesville.

Despite rising well productivity the seven plays will see total oil production drop by an average of 57,000 bpd in May to 5.561 million bpd.

Eagle Ford will see the largest oil production drop, losing 33,000 bpd of oil production and 45 million cubic feet per day of gas production from April to May.

The Niobrara play will see gas production fall to 4.63 million cubic feet per day in May, a steep 50 million cubic feet per day slide from April.

Gas production is expected to drop to 45.971 billion cubic feet per day, a 23 million cubic feet per day loss from April despite sizable output spikes in Utica and Haynesville.

Utica add 35 million cubic feet of gas production per day in May while Haynesville will see production leap by 44 million cubic feet per day.

The Marcellus play will add another 10 million cubic feet of production per day in May bringing its total production to 16.716 billion cubic feet per day, more production than Eagle Ford and Haynesville combined.

The seven regions included in the report accounted for 95 percent of domestic oil production growth and all domestic natural gas production growth from 2011 to 2013, the EIA said.
