DualEx Announces First Quarter 2012 Results

/NOT FOR DISTRIBUTION TO UNITED STATES NEWSWIRE SERVICES OR FOR DISSEMINATION IN THE UNITED STATES/

CALGARY, May 24, 2012 /CNW/ - DualEx Energy International Inc. ("DualEx" or the "Company") (DXE, TSX-V) today filed with Canadian securities authorities its First Quarter Financial Statements and Management's Discussion and Analysis for the period ending March 31, 2012.  Copies of the filed documents may be obtained through www.sedar.com, DualEx's website www.dualexen.com or by emailing DualEx at [email protected].

During the first quarter, production averaged 237 mcfe/d, primarily from the Company's Penészlek gas property in northeast Hungary. In April 2012 the Company announced the successful drilling of the PEN-105A sidetrack well at Penészlek. The well is currently producing approximately 1,000 mcfe/d gross (approximately 400 mcfe/d net).  The Company and its partners plan to add additional perforations and stimulate the well with an acid wash in June 2012.  An acid wash on the original PEN-105 well was very effective, resulting in a doubling of the pre-stimulation production rate. Natural gas prices in Hungary continue to be robust, averaging $15.77 per mcfe in the first quarter 2012.

In Tunisia, the Company completed a 3D seismic survey over the Bouhajla North prospect on its Bouhajla Permit.  The data from this 55 km² 3D survey has been processed and interpreted.  A drilling location has been selected and the Company is in the midst of tendering for services and equipment. The Company anticipates drilling the first exploration well on the Bouhajla North prospect in 2012.

In April 2012 the Company announced that the Tunisian Ministry of Industry and Energy's Comite Consultatif des Hydrocarbures approved DualEx's application to expand the Bouhajla Permit.  The area of the expansion (the "Ktittir Block") represents an increase of 120 km² or 29% of the area of the original Bouhajla Permit.  In consideration for the increase, the Company committed to the recording of a minimum 20 km² of new 3D seismic.  The Ktittir Block lies south of the Company's Bouhajla North prospect. The permit expansion will be formalized upon publication in the official Government Gazette.

Where amounts are expressed on a thousand cubic feet equivalent (mcfe) basis, one barrel of oil has been converted at a ratio one barrel of oil to six thousand cubic feet.  Mcfe's may be misleading, particularly if used in isolation.  A mcfe conversion ratio of one barrel of oil to six thousand cubic feet is based on an energy equivalent conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead.
