Southern Pacific Provides July Operational Update

CALGARY, ALBERTA–(Marketwired – Aug. 19, 2013) – Southern Pacific Resource Corp. (“Southern Pacific” or the “Company”) (TSX:STP) today provided an operational update for the month of July 2013 with respect to the Company’s STP-McKay and STP-Senlac thermal projects.

Total Corporate Production

Total Company production, including bitumen production from STP-McKay and heavy oil from STP-Senlac, averaged 4,483 bbl/d for the month of July 2013, representing a 3% increase from the prior month and an 8% increase over May 2013.

STP-McKay Thermal Project

Average bitumen production for the month of July at McKay was 1,357 bbl/d, a 14% increase over the previous month. On July 8^th, the Company received approval from the Alberta Energy Regulator (“AER”) to proceed with the High Pressure Steam Stimulation (“HPSS”) treatment on the remaining five well pairs on Pad 101. The well pair 1P3 had an HPSS treatment initiated July 9^th which was completed July 19^th. The well was allowed to cool for several days and was placed on stream in late July. Although early, the initial results from the HPSS on this well pair look encouraging, with preliminary test results showing a 60% increase in total fluid production (compared to the previous month’s average fluid rate) and oil cuts averaging about 20%. The pair will now need to be produced for several weeks to clean out the stimulation fluid (condensed steam) and develop steam chambers in newly conformed sections along the well pair length. The next treatment on well pair 1P4 is underway. The remaining three HPSS treatments are anticipated to be completed in the coming months.

STP-Senlac Thermal Project

Senlac heavy oil production averaged 3,126 bbl/d for the month of July. The third steam-assisted gravity drainage (“SAGD”) well pair, K3, was brought on production July 12^th but had to be taken down at the end of July as a result of an electric submersible pump failure. The workover was completed in the first week of August.

Fiscal 2013 Results

Financial and operational results for the fiscal year ended June 30, 2013, will be released on or about September 11, 2013.
