Alaska North Slope crude oil production, including natural gas liquids, averaged 477,364 barrels per day in June, down 10.2 percent, 45,956 bpd, from a May average of 531,827 bpd, and down 2.9 percent from a June 2017 average of 491,527 bpd, a drop of 14,163 bpd.
Volumes are based on Alaska Oil and Gas Conservation Commission data, posted by field and pool on a month-delay basis.
ANS production totals include 41,578 bpd of NGLs - from Prudhoe Bay, Endicott and Northstar - and 106 bpd from Greater Mooses Tooth in the National Petroleum Reserve-Alaska. A small volume from GMT also appeared in May production. The field is under construction and operator ConocoPhillips Alaska told Petroleum News that GMT is not in production and the volumes are due to flowback from a well during the cleanup process to remove drilling mud.
As for the North Slope drop in production from May to June, Alyeska Pipeline Service Co. said Aug. 22 that there were five planned maintenance shutdowns between April 27 and July 6: 12-hour shutdowns April 27, May 25, June 15 and July 6; and an 18-hour shutdown June 23.
Both BP and ConocoPhillips told Petroleum News earlier in the summer that they planned maintenance. The three June shutdowns would have impacted production in that month.
