Wednesday May 11, 7:00 am ET


BELLINGHAM, WA--(MARKET WIRE)--May 11, 2005 -- Avalon Energy Corporation (OTC BB:AVLN.OB - News) announces that it has retained Oso Energy Resources Corp., based in Durango, Colorado, to prepare a Well Development Plan and an AFE for the planned wells on our Uinta Basin prospect.


Oso Energy Corporation is an engineering consulting firm serving the oil and gas industry with primary emphasis on project generation and management. The company has proven expertise in exploration including coring and pilot testing and production operations. Oso Energy has demonstrated its ability to develop and apply innovative solutions that increase reserve value and accelerate cash flow to projects that are known to be complex.

Oso Energy is currently assisting EIS Environmental and Engineering Consulting Ltd. with Avalon's process for permitting and regulatory approval for seismic work.

While in Utah recently, Management of Avalon flew over the Uinta Prospect and confirms that substantial parts of the prospect have been made fully accessible through road development along the ridgelines. This negates any likely need for building additional road access in the early phases of the development program. Full land access should be possible within forty-five days for surface work.

Avalon has an undivided 85% working interest in a giant gas field lease in the prolific natural gas producing Uinta Basin, located in the U.S. Rockies, Utah. The lease comprises 13,189 acres with a potential 4 TCF recoverable gas and is overpressured by a 0.55 - 0.85 gradient.

On behalf of the Company,
