AUSTIN, TEXAS--(MARKET WIRE)--Aug 19, 2008 -- Pantera Petroleum, Inc. (OTC BB:PTPE.OB - News)(Frankfurt:4PP.F - News) (the "Company") announces that its Sibley 84 #1 well in the West Gomez Field has entered production and has begun selling natural gas to Western Gas Resources, Inc., a wholly owned subsidiary of Anadarko Petroleum Corporation (APC - News). On August 16, the on-site engineers opened the well on a 12/64ths inch choke and began selling gas at a natural flow rate of 2.7 million cubic feet of gas per day. Later, the crew opened the choke to 16/64ths of an inch and volume increased to over 4 million cubic feet of gas per day before the crew choked the well back.

Given that the natural flow rate, pre-acidization, of over 4 million cubic feet per day on a 16/64th inch choke is above our projections, we now intend to assess over the next week whether any acidization of the perforations is still required. Over the past week before production, the shut-in pressure continued to increase from 1300 pounds per square inch ("PSI") to 4400 PSI. The crew set the production unit, laid the flow line from the wellhead to the production unit, set the gas meter in place at the pipeline tie-in, laid the flow line from the production unit to the meter, and placed the well into production.

Building upon the success of the Sibley 84 #1 well, we are now moving forward to drill out the additional wells in the Block 83 84, including the Sibley 84 #2, a shallow drill, and the Gulf-Baker 83 #1, an additional re-entry well targeting the Fusselman and Devonian pay zones.

"We are very pleased to have successfully brought the Sibley 84 #1 into production at the natural flow rates we are seeing without the added step of acidization. This is a great event and a great success for our company and our shareholders. Next, we keep moving forward with momentum to drill out our two additional wells in the Block 83 84 project to place them into production," comments Pantera Petroleum's CEO, Chris Metcalf.
