North America Onshore
In 2009, as a result of the Suncor and Petro-Canada merger, the conventional upstream oil and gas facilities from both organizations were brought under common management and operation in the Natural Gas business unit. The number of facilities within the combined Natural Gas business unit of the merged company is much larger than those that were present in the Suncor business. Therefore, large differences in data are apparent between the 2009 operating year and the historical data.
All significant data changes from 2008 are due to the 2009 merger of Petro-Canada and Suncor Energy whereby all data reported is from the combined company facilities for the full 2009 reporting year. In 2010 and 2011, a number of Suncor's Natural Gas assets were divested which explains the downward trend in some of the indicators in this section.
Data included in the 2013 report consists of operated assets only. Thus, the North America Onshore performance indicator section reports on our operated North America Onshore assets, primarily in Western Canada.
On April 15, 2013 Suncor announced the sale of a majority of the conventional portion of its natural gas business in Western Canada, but retained a majority of its unconventional natural gas properties in British Columbia and unconventional oil assets in Alberta. Future reports will reflect this change.
