Petrostar's ETH Field Tests Exceed Expectations

Petrostar Petroleum Corp. (TSX-Venture: PEP. Frankfurt: LMQ; "Petrostar" or the "Company") announces an update to the pilot project testing of the Company's Electric Tank Heater technology (ETH).

In January of this year, SR Rentals of Elk Point, Alberta installed one of Petrostar's Electric Tank Heaters into one of its company's mud rental tanks for testing on an active drilling site. SR Rentals supplies some of Canada's largest oil companies with mud tanks and supplies as necessary equipment used in the drilling of oil and gas wells. The Company's ETH was installed in one of the mud tanks required to hold drilling fluid for the drill rig, in order to keep the drilling fluid from freezing during drilling. Normally the drill rigs boiler would provide heating to the drilling fluid tanks through high-pressure steam hoses. The pilot project parameter was to test the ETH's ability to maintain storage tank drilling fluids at a set temperature in extreme cold conditions.

Petrostar management is happy to announce that after four weeks of on-going use, the ETH performed exceptionally well with no reported problems. Mr. Shane Smith of SR Rentals told the Company that the feedback he had from the drill site of one of Canada's largest oil and gas companies was very positive for the ETH, that the ETH did exactly what the drill crew needed and that there were no problems with keeping a constant temperature control even on the coldest days. The drill crew was very positive about the safety aspect of the heater as it eliminated the need for the high-pressure hoses that are normally used for this application.

This is part of Petrostar management's continued efforts to do independent third party testing of the ETH in different applications under different conditions, to properly commercialize the ETH to the oil and gas industry. More updates will be forthcoming as other pilot projects take place and more information on Petrostar's technologies is available at petrostarpetroleum.ca.
