Operations Update

RockBridge successfully completed drilling its 100/2- 30-48-3-W5M Horizontal Cardium well in late February. The horizontal section of the well was maintained 100% within the Cardium zone and encountered excellent drilling sample derived porosity and inferred permeability. Oil staining was present and consistent throughout the length of the horizontal section. Completion operations were commenced on the well in March. It is anticipated that the well will be equipped with a single well battery and flow lines during and after break up. Productions results are anticipated in May 2011.

RockBridge President and CEO, Richard J. Wolfli, stated, "RockBridge is extremely pleased with the results of the 2-30 well so far. Based on the logs and rock samples, we could not expect better indicators at this point."
