CALGARY, Sept. 10, 2012 /PRNewswire/ - Perpetual Energy Inc. ("Perpetual" or the "Corporation") is pleased to announce further positive results from the Corporation's asset disposition program announced in November 2011. Subsequent to the end of the second quarter Perpetual has closed several transactions for realized proceeds of $14.0 million from the sale of assets in southern and northeast Alberta. The disposed assets consisted of non-core assets in northeast Alberta, shut-in gas over bitumen reserves and the strategic crystallization of value on a portion of an oil pool in southern Alberta. As part of the strategic oil transaction, the Corporation received an additional capital commitment of $1.1 million in late August to advance the development of a Mannville heavy oil pool for implementation of an enhanced oil recovery scheme. The dispositions include production of approximately 147 bbl/d of oil and 2.0 MMcf/d of gas production net to Perpetual. Perpetual will continue to receive the gas over bitumen financial solution associated with the shut-in gas reserves. With the recent dispositions, total proceeds realized through the asset disposition program now total $165 million, exceeding the targeted $75 to $150 million. The proceeds of the dispositions have been applied to reduce outstanding bank debt. Current drawings on the Corporation's credit facility are approximately $85 million relative to a $140 million borrowing base which is confirmed through October 31, 2012, the next scheduled date for the customary semi-annual review by the lenders of the credit facility.
