 SOUTH EAST ETAME 4P APPRAISAL WELLBORE SUCCESSFUL

VAALCO ENERGY, INC. CONFIRMS OIL DISCOVERY IN NEW STEP OUT AREA WITH SOUTH EAST ETAME 4P APPRAISAL WELLBORE

HOUSTON - February 19, 2020 - VAALCO Energy, Inc. (NYSE: EGY; LSE: EGY) (VAALCO or the Company) today announced that the South East Etame 4P appraisal wellbore drilled from the VAALCO operated South East Etame North Tchibala (SEENT) platform offshore Gabon in the Etame Marin permit area successfully encountered oil sands in the Gamba formation.

Highlights

·; Verified the presence of Gamba oil sands in the step out area at South East Etame;

·; Encountered approximately 20 feet of good-quality Gamba oil sands, with similar reservoir quality as exists in the South East Etame 2H well;

·; Drilled the South East Etame 4P appraisal wellbore to a total depth of 6,311 feet;

·; VAALCO currently estimates gross prospective resources of 1 to 2 million barrels of oil (MMBO), or 0.3 to 0.5 MMBO net revenue interest to VAALCO, present in this newly discovered step out area;

·; Drilling did not encounter H2S in the reservoir;

·; Operations are underway to begin drilling the South East Etame 4H development well based on this successful appraisal wellbore, and

·; Expected initial production rates are 1,200 to 2,500 gross BOPD, or 325 to 675 BOPD net revenue interest to VAALCO.

Cary Bounds, Chief Executive Officer, commented, "We are delighted by the continued success from our 2019/2020 drilling campaign, where we have now successfully confirmed additional resources from the two appraisal wellbores and brought two development wells online above predrill expectations. The South East Etame 4P is an important appraisal wellbore and was drilled to further delineate our potential resource base at South East Etame. This step out discovery is accessing new prospective resources that should be converted to 2P reserves by year-end 2020 following the successful drilling of the South East Etame 4H and further technical evaluation. The initial analysis shows that this new step out discovery has similar reservoir quality as the reservoir from which the South East Etame 2H well is producing. These encouraging results allow us to move ahead with plans to drill the South East Etame 4H development well.

We believe that the 2019/2020 drilling campaign has been transformational for VAALCO and set us on the path to achieve our ambitious organic growth plans. The campaign overall has been hugely successful and in aggregate towards the upper end of our internal pre-drill expectations. We have significantly increased overall production with the Etame 9H and Etame 11H development wells that were recently drilled from the Etame platform. Both appraisal wellbores we drilled verified the existence of additional hydrocarbon resources that can be converted to proved reserves over time. In addition, we added production from two recent wells at the Etame platform that were brought back online following a subsea repair on the Etame 4H well and a workover on the Etame 10H well.

We remain optimistic about our outlook for 2020 and believe that we are well positioned to face the headwinds caused by the recent downward pressure on oil prices. We continue to focus on the matters we can control and remain committed to executing on our strategic plan which includes delivering positive operational results while simultaneously considering complementary M&A opportunities, all with a view to generating long-term value for our shareholders."

With the drilling of the South East Etame 4P appraisal wellbore, VAALCO has satisfied the drilling commitment as part of the PSC extension that VAALCO signed in late 2018. This step out discovery at South East Etame is similar in reservoir quality when compared to the Gamba reservoir from which the South East Etame 2H well is being produced. VAALCO plans to drill a third development well in this campaign, the South East Etame 4H, that will target 1.0 to 2.0 million barrels of gross prospective resources, down from the initial predrill estimate of 4.2 MMBO which anticipated a thicker oil column than was encountered in the South East Etame 4P appraisal wellbore. Initial gross production rates are expected to fall within the range from 1,200 to 2,500 BOPD, or 325 to 675 BOPD net revenue interest to VAALCO. Following the completion of the South East Etame 4H well, VAALCO plans to use the contracted drilling rig to perform additional workovers to preemptively replace electrical submersible pumps (ESPs) that are still operating but near the end of their design life.
