MAJOR PROPERTIES
WEYBURN UNIT
ARC is the third largest working interest owner in the Weyburn Unit, which is
operated by PanCanadian Petroleum Ltd. In 2001, through the Startech acquisition, ARC
increased its interest to 6.5 per cent, which nets a production volume to ARC of 1,448 boe/d.
The operator recently initiated a large-scale CO 2 tertiary recovery scheme in
one area of this large field to augment an extisting waterflood program. Optimization of
the waterflood has continued, including infill drilling to improve waterflood and CO 2 flood
production and recoveries. PanCanadian will continue to monitor the performance of the
flood, adjust injection practices and drill additional infill wells in 2002. The success of the
CO 2 recovery scheme is expected to lead to further phases of tertiary recovery in this
large field.
SOUTHEAST SASKATCHEWAN – OTHER PROPERTIES
ARC currently produces 3,693 boe/d from other southeast Saskatchewan
properties. Alida and Queensdale are representative of several smaller properties that
produce high quality 30° to 42° API crude oil from various formations. ARC drilled eight
horizontal wells on a number of properties in southeast Saskatchewan in 2001 with a
100 per cent success rate. These new wells added 900 bbl/d to ARC’s production in
2001. ARC’s working interests in the new wells range from 50 to 100 per cent.
