ANS crude production down 1% from August For September, North Slope averages 474,810 bpd, off from 478,842 bpd; August Cook Inlet production down marginally from July KRISTEN NELSON Petroleum News
Alaska North Slope crude oil production averaged 474,810 barrels per day in September, down 0.84 percent from an August average of 478,842 bpd. The largest month-over-month changes were at Hilcorp Alaska-operated Endicott and at BP Exploration (Alaska)-operated Lisburne.
Endicott averaged 8,521 bpd for September, up 111.4 percent from an August average of 4,030 bpd. Endicott production has typically averaged more than 8,000 bpd, but dropped into the 6,000-bpd range in late August and then in September ranged from a low of 4 bpd to a high of more than 8,000 bpd at the end of that month before settling back into the 8,000-bpd range in September.
Endicott production includes satellite production from Sag Delta, Eider and Minke, as well as production from the Glacier Oil & Gas Corp. subsidiary Savant Alaska-operated Badami field and the ExxonMobil-operated Point Thomson field.
Badami averaged 981 bpd in August, on par with 980 bpd in September.
Point Thomson averaged 1,230 bpd in August, up 16 percent, 169 bpd, from a July average of 1,061 bpd.
Information for September comes from the Alaska Department of Revenue’s Tax Division which reports North Slope oil production consolidated by major production centers and provides daily production and monthly averages. More detailed information, including Cook Inlet and individual North Slope fields and pools, is reported by the Alaska Oil and Gas Conservation Commission on a month-delay basis.
Lisburne, Prudhoe Lisburne production averaged 6,342 bpd in September, down 65.7 percent, 12,153 bpd, from an August average of 18,495 bpd, a drop in production due to scheduled maintenance which began in late August and took the field’s facilities completely offline. It came back online Sept. 20. Production from Lisburne, part of greater Prudhoe Bay, includes Point McIntyre, Niakuk and Raven.
Production from BP-operated Prudhoe Bay, the North Slope’s largest field, averaged 258,806 bpd in September, down 2.2 percent, 5,743 bpd, from an August average of 264,549 bpd.
