Enbridge completes North Dakota pipeline expansion

* Completes expansion of system for Bakken oil

* Boosts capacity to 160,000 bpd (In U.S. dollars unless noted)

CALGARY, Alberta Jan 5 (Reuters) - Enbridge Inc (ENB.TO), Canada's No, 2 pipeline company, said on Tuesday it has completed a $147 million expansion of its North Dakota oil pipeline system to handle rising production from the prolific Bakken oilfield.

Capacity on the system, controlled by Enbridge's U.S. affiliate Enbridge Energy Partners LP (EEP.N), has been boosted by 40,000 barrels per day at the system's western end, which runs to Minot, North Dakota, while the Minot to Clearbrook, Minnesota, leg of the system can handle an additional 51,000 bpd.

The expansion, which opened on Jan. 1, raises the total capacity of Enbridge's North Dakota system to 161,000 bpd to accommodate rising output from the Bakken play, a massive oilfield lying under parts of North Dakota, Montana and southern Saskatchewan.

Output from the multibillion-barrel field is rising as oil companies apply new drilling and production techniques to exploit the Bakken's technically challenging geology.

Enbridge shares rose 10 Canadian cents to C$48.15 at midmorning on the Toronto Stock Exchange while its U.S. partnership's units were up 40 cents at $54.98 in New York.
