VAALCO Energy has started the first production from the Etame 10-H development well, offshore Gabon.

It is the second development well drilled from the newly installed Etame platform.

Etame 10-H was drilled using Transocean’s Constellation II jack-up rig to a measured depth of 3,144m. It encountered more than 180m of reservoir within an oil-bearing portion of the Gamba sand.

"VAALCO has produced over 85 million barrels of oil from the Etame Marin block."

Upon completion, VAALCO tested the horizontal development well at the rate of approximately 3,200b/d on a gross basis with small amount of water and zero hydrogen sulfide. 

The company said the well is currently producing around 3,000bopd of oil.

VAALCO CEO Steve Guidry said: "We are very pleased with the results from the Etame 10-H well and we are eager to continue our current drilling programme offshore Gabon.

"VAALCO has produced over 85 million barrels of oil from the Etame Marin block and, with our two new platforms, we are well-positioned to continue to deliver a growing production profile through most of 2015."

The Constellation II rig will now be moved to drill further development wells from the southeast Etame/N.Tchibala (SEENT) platform.

The company will start with the south-east Etame 2-H well, located in the southeast Etame field.

VAALCO plans to carry out an extended well test of the Etame 8-H well, which was drilled in the fourth quarter of 2014, to identify and quantify the presence of H2S.

The well test is expected to be performed within the first quarter of 2015.
