ConocoPhillips and Anadarko to expand capacity of Alpine field
ConocoPhillips and Anadarko Petroleum unveiled plans to increase oil production capacity at the Alpine field on
Alaska's North Slope. The Alpine Capacity Expansion Project Phase 1 (ACX1) will start up in late 2004. ACX1 also will
increase both the water and gas handling capacities of the plant. Both are important for increasing oil production
and maintaining reservoir pressure. Additional expansion opportunities are still being studied.
The $ 60 mm Phase I project will initially increase daily oil production by 5,000 bpd. The field, which started
production in November 2000, is currently producing 100,000 bpd of oil.
To date, 68 wells -- 34 production and 34 injection -- of the planned 94 wells have been completed at the two Alpine
drill sites. Alpine has been developed exclusively with horizontal well technology and employs enhanced oil recovery
(EOR).
The field's unique design and the use of EOR will help extract more oil from the reservoir. NANA/Colt Engineering LLC
in Anchorage is performing the ACX1 design engineering. Truckable module fabrication will be put out for bid once
detailed engineering is complete. ACX1 North Slope construction has previously been awarded to VECO Alaska.
The 40,000-acre field was developed on just 97 acres, or two-tenths of 1 % of the field area. In addition, Alpine is
a near zero-discharge facility. The waste generated is reused, recycled or properly disposed.
There is no permanent road to the field; in the winter, ice roads are constructed to allow transportation of
equipment and drilling supplies to the site. These roads minimize environmental impacts, because in the spring the
ice roads melt, leaving no trace on the tundra. Small aircraft also provide service to the field.
The Alpine discovery was declared commercial in 1996. Alpine is the largest onshore oil field discovered in the
United States in more than a decade. It also is the western-most producing oil field on Alaska's North Slope. The
field is located in the Colville River area, 34 miles west of the Kuparuk River field, near the border of the
National Petroleum Reserve-Alaska.
ConocoPhillips Alaska operates the Alpine field, which is owned 78 % by ConocoPhillips and 22 % by Anadarko
Petroleum.
