VAALCO Energy Provides Update on Drilling Program

Drilling Results Demonstrate Successful Expansion of Ebouri Field

HOUSTON, Dec. 31 /PRNewswire-FirstCall/ -- VAALCO Energy, Inc. (NYSE: EGY) today provided an update on the new development well being drilled in the Ebouri field and the new appraisal well (North Ebouri) being drilled in the Etame block. VAALCO commenced drilling these wells in November with the jack-up rigs Adriatic 6 and Pride Cabinda, respectively, as previously announced.

For the development well in the Ebouri field, VAALCO announced that it has drilled one pilot hole to the south of the original Ebouri discovery and a second pilot hole to the northeast of the original discovery. Both of these pilot holes were successful in delineating additional Gamba sandstone reservoir above the oil water contact, thereby increasing the acreage and reserves of the Ebouri field. VAALCO is currently completing the development well horizontally on the same orientation as the second pilot hole. First oil production from this well is expected in January 2009.

The Company also announced that it drilled the North Ebouri appraisal well in the Etame block approximately 1.5 miles to the northeast of the Ebouri platform and found 21 feet of oil column, further expanding the Ebouri field. VAALCO is now planning a sidetrack to optimize the location for a potential second horizontal development well. In addition, the Company is planning two exploration wells (North Etame and South East Etame) on newly mapped structures. The wells will be drilled back to back using Pride Cabinda.

VAALCO continues to expect production at a rate sufficient to bring total production from the Etame license area to approximately 25,000 barrels of oil per day (bopd). The Etame license production areas currently produce approximately 20,000 bopd, of which VAALCO has a 28.1% working interest.

"Results from the Ebouri development drilling have exceeded expectations, and we are pleased with the initial results from our drilling program in the Etame block, with more wells to come," said Robert L. Gerry, III, Chairman and CEO of VAALCO. "We have substantially enlarged the productive acreage of the Ebouri field, thereby greatly enhancing the recoverable reserves. We look forward to continued success with our exploration program."

Additional wells planned over the coming months include:

    --  Two exploratory wells onshore Gabon in the Mutamba concession:  VAALCO
        is currently mobilizing the Nabors 864 rig to the first of the two
        planned drilling locations and expects to commence drilling the first
        exploratory well in early February 2009.  Combined potential reserves
        for these two wells are expected to be in excess of 30 million barrels. 
        VAALCO has a 100% working interest in the onshore Mutamba block.

    --  One exploratory well in Angola:  The Company expects to move forward on
        the planning for a well on Angola Block 5 during the third quarter of
        2009 depending upon rig availability.  The Company has recommended to
        the consortium a prospect with three objective zones, both above and
        below the salt layer on the block.  Total potential from all three
        objectives is 150 million gross barrels.  VAALCO has a 40% working
        interest in Block 5.

    --  Interest in North Sea:  VAALCO has a 25% interest in a gas prospect on
        Block 48/25c in the British North Sea.  The Company is participating
        with Century Exploration on the well, which is an offset to a former
        Shell gas discovery made in 1987.  3-D seismic data indicates the
        ability to get higher on the structure than the earlier well, increasing
        the potential reserves to 60 Bcf.  Due to a delay in the receipt of the
        rig from the current operator, VAALCO expects that drilling will begin
        in January 2009.

VAALCO's development and exploration wells planned over the coming months expose VAALCO to over 50 million net barrels, or an 8-fold potential increase to the Company's current 6.2 million barrels of proved reserves.
