Raven Well Hits Primary Gas Targets

The second well (Grable 15#1) in the Raven exploration project has reached planned total depth of 11,000 feet and as a result of the log analysis, the decision has been made to set production casing. As forecasted, the two primary objective zones the “C” sand and the “Price” sand were encountered correlating with strong gas shows from the mud log during the drilling phase.

“This test further reinforces the execution of our “Long Play” strategy that the Board of Directors has put in place for the growth of Pryme along with confirming our robust collection of exploration projects that we are working to convert into real value for our shareholders. We are very happy with the logging. Getting Raven and Turner Bayou underway leading up to the Christmas break should see Pryme add natural gas and condensate to its existing oil revenues”, said Justin Pettett, Pryme’s Managing Director. “The Pryme team remains focused on our goal of generating earnings and building reserves towards our target of building a A$300-A$500 million company in 3 to 5 years. We’re expecting a strong 2008 to build on these latest results.”

A natural gas discharge pipeline will be run and surface facilities installed in preparation for the fracture stimulation of the deepest zone. Just like the Spinks well we plan to test the well directly into the sales line to preserve the integrity of the formations. This completion phase should take approximately 60 days with the sale of first products planned for some time commencing in March 2008.
