Pengrowth Closes Southeast Saskatchewan Asset Disposition

CALGARY, ALBERTA--(Marketwired - Sept. 9, 2013) - Pengrowth Energy Corporation (TSX:PGF) (NYSE:PGH) has closed the previously announced divestiture of its non-core southeast Saskatchewan assets, effective June 1, 2013. Proceeds from the sale are $510 million, prior to closing adjustments.

The assets sold had production of approximately 5,700 barrels of oil equivalent per day (boe/d) (93% liquids) and proved plus probable reserves of 21.3 million barrels assigned to them at December 31, 2012, according to the independent reserve evaluators GLJ Petroleum Consultants Ltd.

Including this transaction, by September 30, 2013, Pengrowth expects to have sold approximately $1 billion of non-core assets in 2013.

"We are pleased to have achieved the goal we set for ourselves in January of this year - to dispose of up to $1 billion of non-core assets so as to ensure that funding was in place by year-end to develop the first 12,500 bbl/d phase of our Lindbergh thermal project by year-end," said Derek Evans, Pengrowth's President and CEO. "Being able to execute a successful disposition program in today's market environment puts us firmly on the path to bring the first commercial phase of Lindbergh on production by the end of next year, which offers the exciting prospect of growing, profitable, low decline, long reserve life oil production production."
