CALGARY, Aug. 30 /CNW/ - During the second quarter of 2007, energy producers undertook modest drilling. Suntec generated $36,302 and $77,670 of revenue and a net loss of $764,396 and $959,678 during the three and six months ended June 30, 2007.

Suntec has realized substantially lower revenue than expected as the energy industry responds to prolonged, lower natural gas prices and higher drilling costs through a reduction in well drilling and fracturing. This trend is expected to continue until Suntec's clients increase their drilling and fracturing activity levels as a result of higher natural gas prices or lower drilling costs. The Suntec water treatment plant suspended operations in July 2007 pending an increase in industry activity.

About Suntec

Suntec Pure Water Technologies Inc. treats and recycles oilfield waste water and sells recycled water, methanol water and potassium chloride. Waste water and sand is transported by truck from well fracturing operations to Suntec's oilfield waste water treatment facility, located approximately 80 kilometers southeast of Calgary, Alberta. The recycling process removes residual contaminants from the water. Treated and recycled water, methanol water and potassium chloride are sold to oil and gas industry operators for re-use in the oil and gas drilling and development process while the sand is shipped to a recycler. The waste water, as treated and recycled by Suntec, would otherwise be disposed of through the existing method of deep well injection, removing the water from the hydrological cycle.
