VAALCO Energy Purchases Bakken Acreage

HOUSTON, TEXAS – May 31, 2011 – VAALCO Energy, Inc. (“VAALCO”) (NYSE: EGY) today announced the purchase from a privately held company of a 70% working interest in 5,214 acres in Sheridan County, Montana. The acreage directly adjoins the Flat Lake Field which successfully produces from the Middle Bakken formation.
Robert Gerry, Chairman and CEO said, “We are highly optimistic that this acreage will be productive from the Bakken and possibly the Three Forks formation, thereby having the potential to add significant reserves and cash flow to VAALCO.”
“We believe there could be 100 million barrels of original oil in place associated with this acreage and with a recovery factor of between 5% – 10% it is an exciting undertaking for us,” Mr. Gerry continued. “Our partner has participated in over 200 Bakken wells and will retain a 30% working interest in the prospect. We continue to evaluate other domestic opportunities, both conventional and unconventional, to build a portfolio of assets to complement our West African activities.”
Financial terms were not disclosed as additional opportunities in the area are being reviewed by VAALCO. Operatorship is being discussed by the partners with a well anticipated to be drilled in the fourth quarter of 2011 at a net cost to VAALCO of approximately $3.5 million.

VAALCO Energy Announces First Quarter 2011 Results

Reports 56% Increase in Year-Over-Year Revenues

HOUSTON – May 09, 2011 – VAALCO Energy, Inc. (NYSE: EGY) today reported net income attributable to VAALCO of $11.2 million or $0.19 per diluted share for the first quarter of 2011 compared to net income attributable to VAALCO of $6.0 million or $0.11 per diluted share for the comparable period in 2010. First quarter 2011 revenues were $46.8 million compared to $30.0 million in the first quarter of 2010, an increase of 56%. First quarter 2011 results reflect increases in both production levels and oil prices compared to the first quarter of 2010.

Exploration and Development Update
The Company provided the following update on its exploration and development program:
Gabon: VAALCO and its partners in the Etame Marin block are meeting in June 2011 to finalize the next drilling program, which is anticipated to begin in late 2011. Additional development wells and an exploration well are expected to be approved by the consortium. Seismic reprocessing is underway on the Mutamba Iroru block onshore Gabon and VAALCO is on track to drill an exploration well on the block in early 2012.
Angola: VAALCO has been encouraged by the continuing dialogue with the Republic of Angola regarding drilling plans for Block 5 offshore Angola. The Company is moving forward to purchase long lead-time items and entering into contracts with the anticipation that VAALCO will begin drilling the first of two exploration wells by the end of November 2011. VAALCO is optimistic that a new partner will join the Company on this block shortly. In addition, the Angolan government has provided verbal assurances that enable VAALCO to proceed with plans to drill the two exploration wells.
United States: The Company spudded the first well on the Granite Wash Formation lease in Hemphill County, Texas on May 9, 2011. The well will take approximately 45 days to drill followed by hydraulic fracturing, which is expected to take place in July 2011.

Financial Results Discussion
During the first quarter of 2011, the Company sold approximately 450,800 net barrels of oil equivalent at an average price of $103.76 per barrel compared to 403,200 net barrels of oil equivalent at an average price of $74.33 per barrel in the first quarter of 2010. The Company reported operating income of $31.3 million in the first quarter of 2011 compared to operating income of $17.9 million in the first quarter of 2010.
Crude oil production averaged 23,200 gross barrels of oil per day (bopd) in the three months ended March 31, 2011 compared to approximately 19,300 gross bopd in the three months ended March 31, 2010. The increase in year-over-year production volumes primarily reflects production from three new development wells drilled offshore Gabon in 2010, plus the successful workover of the Ebouri 3-H well to replace submersible pumps, also offshore Gabon.
Total production expenses were $5.2 million for the first quarter of 2011 compared to $4.9 million in the prior year quarter. The increase in year-over-year production expense was primarily due to retroactive compensation adjustments in Gabon totaling $0.3 million.
Exploration expense was $1.1 million in the first quarter of 2011 compared to $1.0 million of expense in the prior year quarter.
Income tax expense was $18.3 million for the first quarter of 2011 compared to $10.8 million in the prior year quarter. The increase in income tax in the first quarter 2011 over the comparable period in 2010 was due to the 56% increase in oil revenues and a higher percentage of oil production allocated as “profit oil” vs. “cost oil”.
Balance Sheet
On March 31, 2011, the Company had unrestricted cash of $92.6 million and no debt. The Company expects its cash balances plus cash from operations will be more than sufficient to fund the Company’s remaining 2011 capital expenditure budget.
