Alaska North Slope production up in June, driven by Northstar Producing from six wells, Northstar had a one-day peak of 71,876 barrels; Alpine, producing from 25 wells, had a one-day peak of 100,787 barrels Kristen Nelson PNA editor-in-chief
Alaska North Slope crude oil production averaged 1,032,085 barrels per day in June, up 1.3 percent from a May average of 1,018,802 bpd.
The increase was driven by Northstar, where production averaged 60,980 bpd in June, up from 34,949 bpd in May.
Northstar had compressor problems early in June, the Department of Revenue said July 2. Production at the field, which was 72,434 bpd June 1, dropped to 7,321 bpd June 6, was back up to 71,892 bpd June 10 and continued to range from highs above 70,000 bpd to lows of some 40,000-50,000 bpd through the remainder of the month.
Field operator BP Exploration (Alaska) Inc. had problems at Northstar earlier in the year. An electric motor failed on a low-pressure gas compressor in April and the motor had to be swapped out.
Northstar producing from six wells In May, the most recent month for which the Alaska Oil and Gas Conservation Commission provides well data, Northstar was producing from six well completions. Averaged against peak one-day production in May of 71,876 barrels, that is an average of 11,979 barrels per well.
That compares with the Alpine field, which peaked in May at 100,787 barrels a day from 25 well completions, an average of 4,031 barrels per well. Alpine began production in November 2000, Northstar a year later.
Production was also up in June at the Kuparuk River field (including West Sak, Tabasco, Tarn and Meltwater), averaging 211,015 bpd, up 0.83 percent from 209,288 bpd in May.
Milne Point (including Schrader Bluff and Sag River) averaged 50,850 bpd in June, about even with a May average of 50,733 bpd.
Lisburne (including Point McIntyre, Niakuk, West Beach and North Prudhoe Bay State) also held about even, averaging 71,288 bpd in June compared to a May average of 71,228 bpd.
Prudhoe production down Production from Prudhoe Bay, Endicott and Alpine was down from May to June.
Prudhoe Bay (including Midnight Sun, Aurora, Polaris and Borealis) averaged 511,991 bpd in June, down 2.3 percent from a May average of 524,108 bpd.
Endicott (including Sag Delta, Eider and Badami) averaged 30,999 bpd in June, down 2.7 percent from a May average of 31,868 bpd.
Alpine (including Nanuq) averaged 94,962 bpd in June, down 1.7 percent from a May average of 96,628 bpd.
