October production up 7% from September
Alaska North Slope crude, NGLs, average 508,751 bpd, up 33,103 bpd, mostly from Prudhoe; Cook Inlet averages 13,613 bpd, up 1% Kristen Nelson Petroleum News
Alaska North Slope production averaged 508,751 barrels per day in October, up 7%, 33,103 bpd, from a September average of 475,648, but down 2.5% from an October 2018 average of 521,782 bpd.
ANS crude oil production averaged 461,170 bpd, up 5.8%, 25,292 bpd, from a September average of 435,878 bpd but down 2.2% from an October 2018 average of 471,753 bpd. ANS crude accounts for 90.7% of production, with 9.3% coming from natural gas liquids, which averaged 47,581 bpd in October, up 19.6%, 7,811 bpd, from a September average of 39,770 bpd, but down 4.9% from an October 2018 average of 50,031 bpd. Production from only three North Slope fields, Endicott, Northstar and Prudhoe Bay, includes 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.
The largest month over month volume increase was from the Slope’s largest field, BP Exploration (Alaska) operated Prudhoe Bay, which averaged 254,432 bpd (209,781 bpd of crude and 44,650 bpd of NGLs), up 31,520 bpd, 14.1%, from a September average of 222,911 bpd (185,163 bpd of crude and 37,749 bpd of NGLs) but down 5.3% from an October 2018 average of 268,623 bpd (221,607 bpd of crude and 47,016 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.
Other increases The Hilcorp Alaska operated Endicott field had the largest month over month percentage increase, up 57.6%, 2,732 bpd, at 7,473 bpd, from a September average of 4,742 bpd, and also up 3.8% from an October 2018 average of 7,198 bpd. Hilcorp’s most recent plan of development for Endicott, the Duck Island unit, listed facilities work in September, which likely accounted for the lower volumes in that month. Endicott crude production averaged 6,564 bpd in October, 87.8% of the field’s production, and NGLs averaged 909 bpd, 12.2% of production.
The ConocoPhillips Alaska operated Colville River field averaged 58,189 bpd in October, up 7.2%, 3,918 bpd, from a September average of 54,271 bpd, but down 6.6% from an October 2018 average of 62,266 bpd.
In addition to oil from the main Alpine pool, Colville production includes satellite production from Fiord, Nanuq and Qannik.
ConocoPhillips’s Greater Mooses Tooth in the National Petroleum Reserve-Alaska, which came online in October 2018, averaged 7,481 bpd this October, up 2.3%, 165 bpd, from a September average of 7,316, but down 3.5% from an October 2018 average of 7,754 bpd. There are three wells in production at GMT, but one wells, GMTU MT6-05, accounted for 6,582 bpd in October, 88% of the field’s production.
The Hilcorp Alaska operated Northstar field averaged 9,172 bpd in October, up 1.5%, 137 bpd, from a September average of 9,035 bpd but down 17.4% from an October 2018 average of 11,103 bpd. Crude oil production at Northstar averaged 7,150 bpd in October, 78% of the field’s production, while NGLs averaged 2,022 bpd, 22% of production.
Down month over month Production from other North Slope fields was down, month over month.
The largest per barrel drop was at the ConocoPhillips Alaska operated Kuparuk River field, the Slope’s second largest, where production averaged 107,921 bpd in October, down 1.6%, 1,707 bpd, from a September average of 109,628, and down 2.5% from an October 2018 average of 110,648 bpd. In addition to the main Kuparuk pool, Kuparuk produces from satellites at Meltwater, Tabasco and Tarn, and from West Sak.
The Hilcorp Alaska operated Milne Point field averaged 29,571 bpd in October, down 5.2%, 1,622 bpd, from a September average of 31,192 bpd but up 40.2% from an October 2018 average of 21,099 bpd. Milne production dropped steeply in August, to 11,066 bpd from 26,768 bpd in July, but production in the plus-20,000 bpd range has been the norm at the field, where the biggest recent change was in April when Hilcorp brought the Moose Pad online, and production kicked up from the mid-20,000 bpd range to 25,000-plus, where with the exception of August volumes it has remained. August is part of the annual planned maintenance season on the North Slope, frequently accounting for temporary drops in production.
Eni’s Oooguruk field averaged 8,276 bpd in October, down 11.8%, 1,103 bpd, from a September average of 9,379 and down 17.4% from an October 2018 average of 10,025 bpd.
Eni’s Nikaitchuq field averaged 19,946 bpd in October, down 3.4%, 706 bpd, from a September average of 20,652 bpd, but up 24% from an October 2018 average of 16,091 bpd.
