PETROSTAR'S DHT TECHNOLOGY DRAWS INTERNATIONAL INTEREST
Petrostar Petroleum Corp. has received a request from the United States purchasing agent for Bariven SA, the oil and gas field services provider for the Venezuelan petroleum industry. The request is for a quote to provide two DHT units that will meet operational requirements in oil wells at the 3,000-foot to 5,000-foot operational depth. Petrostar Petroleum is pleased that the continuing DHT field testing in Maidstone and Northern Saskatchewan has drawn international attention.
The DHT 3 and delivery system is still currently performing a subsurface test at the 16A/6 well site at Petrostar Petroleum's Maidstone project located in Maidstone, Sask. This latest test has been continuous from mid-February, 2009. The latest DHT is capable of higher temperature performance then previous models. The DHT is currently running at a depth of 499 metres at well A16-6-48-23w3m Maidstone. The tool temp set point has been brought up to plus 240 C and a running temperature plus 256 C. The fluid temperature is plus 167 C in the well bore.
This current DHT model incorporates all modifications and improvements from field tests of the DHT 1 and DHT 2 models, as well as having a 5,000-foot capability. This unit is expected to influence offsetting wells 1A16HZ/6, 9/6, 10/6 and D16HZ/6. The wells are 150 metres from 16A/6, and as they are located upon the field high, production enhancement is anticipated. The well data will be available from a real-time wireless monitoring system that provides temperature, gas production and system performance as well as shut down alarms. This data will provide further backup to data received previously from tests at wells 9/6 and 15/6.
Also, the TSX Venture Exchange has accepted for filing a non-brokered private placement of 1,539,000 units of the company at a price of 10 cents per unit for a total of $153,000. Each unit will comprise one flow-through share in the capital of the company and one non-transferable share purchase warrant. Each full warrant will entitle the holder thereof to purchase one additional common share of the company for a period of two years following the closing date at a price of 12 cents per share in the first year and 15 cents per share in the second year. The private placement is subject to a four-month hold period.
On behalf of the Board of Directors,
Robert A. Sim
President and Director
