Alaska North Slope crude oil and natural gas liquids production averaged 515,292 barrels per day in April, down 1.4%, 7,042 bpd, from a March average of 522,334 bpd. Crude averaged 460,075 bpd; NGLs averaged 55,216 bpd.

ANS production for April was down 3.6% from April 2018, when it averaged 534,415 bpd, 482,018 bpd of crude oil and 52,396 bpd of NGLs.

Production data reported here is from the Alaska Oil and Gas Conservation Commission, which provides volumes by field and well on a month-delay basis. NGLs are shown for fields where they are produced - Prudhoe Bay, Endicott and Northstar.

The largest month-over-month increase, both in barrels and in percentage, was at the Hilcorp Alaska-operated Milne Point field, which averaged 25,260 bpd in April, up 10.3%, 2,350 bpd, from a March average of 22,910 and up 17.7% from an April 2018 average of 21,457 bpd. Production at the Slopeís newest pad, Milne Pointís Moose Pad, came online in early April, with Hilcorp reporting an initial rate of 3,000 bpd from two wells.

Other North Slope fields with month-over-month production increases include Endicott, Nikaitchuq and Northstar.

Production at the Hilcorp-operated Endicott field increased marginally, averaging 7,328 bpd (6,443 bpd of crude and 885 bpd of NGLs), up 0.2%, 15 bpd, from a March average of 7,313 bod (6,443 bpd of crude and 870 bpd of NGLs). The field was also up year-over-year, an increase of 11.1% from an April 2018 average of 6,594 bpd (5,979 bpd of crude and 615 bpd of NGLs).

Eniís Nikaitchuq field averaged 16,877 bpd in April, up 2.1%, 350 bpd, from an April average of 16,527 bpd, but down 5.5% from an April 2018 average of 17,853 bpd.

The Hilcorp-operated Northstar field averaged 11,373 bpd in April (8,510 bpd of crude and 2,863 bpd of NGLs), up 2.2%, 239 bpd, from a March average of 11,133 bpd (8,200 bpd of crude and 2,933 bpd of NGLs), but down 1.1% from an April 2018 average of 11,493 bpd (8,770 bpd of crude and 2,723 bpd of NGLs).

Down month-over-month

All other North Slope fields had month-over-month production declines.

The BP Exploration (Alaska)-operated Prudhoe Bay field, the Slopeís largest, averaged 272,748 bpd in April (221,280 bpd of crude and 51,469 bpd of NGLs), down 0.4%, 1,018 bpd, from a March average of 273,766 bpd (220,977 bpd of crude and 52,789 bpd of NGLs) and down 5.4% from an April 2018 average of 288,362 bpd (239,304 bpd of crude and 49,058 bpd of NGLs).

In addition to the primary reservoir, production volumes from Prudhoe include Aurora, Borealis, Lisburne, Midnight Sun, Niakuk, Polaris, Point McIntyre, Put River, Raven and Schrader Bluff.

The month-over-month decline was small at ConocoPhillips Alaskaís Greater Mooses Tooth, which averaged 12,253 bpd in April, down 0.5%, 57 bpd, from a March average of 12,310 bpd. Greater Mooses Tooth, which is in the National Petroleum Reserve-Alaska, came online in October and is producing from three wells.

ConocoPhillipsí Colville River unit averaged 52,661 bpd in April, down 2.7%, 1,482 bpd, from a March average of 54,142 bpd, and down 20.2% from an April 2018 average of 66,001 bpd.

In addition to oil from the main Alpine pool, Colville production includes satellite production from Fiord, Nanuq and Qannik.
