Cenovus Energy says it will pay $17.7 billion Canadian (US$ 13.2 billion) for most of ConocoPhillips' Canadian assets.

Houston-based ConocoPhillips is the latest company to reduce exposure to Canada's oil sands — the world's third-largest oil reserves.

Cenovus CEO Brian Ferguson called it a "transformational acquisition" for the Calgary-based company.

The deal includes ConocoPhillips's 50 percent interest in FCCL Partnership, an oil sands venture between the two companies in northern Alberta, as well as the majority of ConocoPhillips's Deep Basin conventional assets in Alberta and British Columbia. The combined assets have forecast 2017 production of approximately 298,000 barrels of oil equivalent daily.

Royal Dutch Shell earlier this month sold most of its oil sands holdings to Canadian Natural Resources Ltd.

Oil sands are a type of unconventional petroleum deposit.
