Suncor Energy sells non-core Wilson Creek assets

(All financial figures are approximate and in Canadian dollars unless otherwise noted.)

CALGARY, ALBERTA--(Marketwired - Sep 3, 2014) - Suncor Energy today announced it has reached an agreement to sell its Wilson Creek assets located near Rimbey, Alberta to Tamarack Acquisition Corp., a wholly owned subsidiary of Tamarack Valley Energy Ltd., for $168.5 million. Estimated net production year to date from this business was 1,702 boe/d.

Wilson Creek is a Cardium-focused operation (over 80% average Suncor working interest) and includes a 52% working interest in the operated Wilson Creek Unit No. 1 (which produces liquids-rich gas) and associated facilities.

"The sale of the Wilson Creek assets is consistent with our disciplined approach to managing our portfolio," said Steve Williams, president and chief executive officer. "These are high-quality assets that no longer fit with our core business. We will continue to invest in those assets which are complementary to our core business and fit our long-term strategy."

The purchase price is subject to closing adjustments based on an adjustment date of July 1, 2014, typical of transactions of this nature. The sale is subject to regulatory approval, including under the Competition Act, and is expected to close in the fourth quarter of 2014.

Certain natural gas volumes have been converted to barrels of oil equivalent (boe) on the basis of one barrel to six thousand cubic feet. Any figure presented in boe may be misleading, particularly if used in isolation. A conversion ratio of one bbl of crude oil or natural gas liquids to six thousand cubic feet of natural gas is based on an energy equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead. Given that the value ratio based on the current price of crude oil as compared to natural gas is significantly different from the energy equivalency of 6:1, utilizing a conversion on a 6:1 basis may be misleading as an indication of value.
