News & Updates

Petrostar Petroleum Corporation (TSX.V-PEP, Frankfurt-LMQ, the “Company”) announces it has completed the surface water test on its Down Hole Heating Device.

The results of the surface water test, according the Company’s lead electrical engineer, Thomas Sun, P. Eng. of Valax Manufacturing Inc. a leading custom industrial custom fabricator, was an unequivocal major success. The Down Hole Heating Device was submerged in water for 33 hours and surpassed all metrics for electrical connection and fluid sealant integrity. More importantly, the DHT reached target temperatures to sufficiently heat the water to generate steam, which in a closed environment will result in down hole pressure.

The success of the surface water test is a significant milestone achieved by Petrostar as it brings the Company one step closer to proving and ultimately commercializing this revolutionary enhanced oil recovery technology. The Down Hole Heating Device has the potential of revitalizing tens of thousands of proven North American medium and heavy oil wells that have been suspended due to insufficient reservoir pressure. As a point comparison of the commercial potential of the Down Hole Heating Device, Steam Assisted Gravity Drainage (SAG-D) technology produced $3.4 Billion in commercial licensing revenue within two years of its introduction to North American Oil & Gas producers.

With the successful completion of the surface test, the Company is positioned to move to the next stages of the testing phase. The following outlines the Company’s plans for the balance of the field testing process, subject to weather conditions:

• Specialized electrical cable to go through coil tubing process at Sanjel Coil Tubing facilities in Red Deer, AB by mid-April 2007.
• Well preparation at the Company’s Maidstone facility to be completed by third week of April 2007.
• Down Hole Heating Device to be placed 575 meters down Company’s well by end of April 2007.
• Down Hole Heating Device left within the well for 10 days.
• Results of the test to be analyzed by mid May 2007.

The field testing will be led by Bernie Cabot of Western Petroleum Management, a leading Oil and Gas project management firm based in Calgary, Alberta (www.westpetro.com).

On Behalf of the Board of Directors,

Robert A. Sim
President
