Vaalco Energy Inc., Houston, reported start of production from its Etame 10-H development well, the second such well drilled from the recently installed Etame platform offshore Gabon (OGJ Online, Oct. 17, 2014).
The horizontal development well was drilled to 3,144 m measured depth while intersecting more than 180 m of high-quality reservoir within an oil-bearing portion of the Gamba Sand, Vaalco said.
Following completion operations, the well was tested at the rate of 3,200 bo/d on a gross basis with negligible amounts of water and no hydrogen sulfide. The well is currently being produced at 3,000 bo/d.
Production from the well, drilled on the Etame Marin block, will add to the 85 million bbl of oil already produced from the block. “With our two new platforms, we are well positioned to continue to deliver a growing production profile through most of 2015,” Vaalco said.
The contracted Transocean Constellation II jack up rig is now being mobilized to drill additional development wells from the Southeast Etame-North Tchibala, (SEENT) platform, beginning with the Southeast Etame 2-H well in Southeast Etame field, where the company and its partners drilled a successful exploration well in 2010.
Following the mobilization of the rig to the SEENT platform, Vaalco plans to conduct an extended well test of the Etame 8-H well, drilled in fourth-quarter 2014, to confirm and quantify the presence of H2S, which was detected during the initial 17-hr flow test. The well test is expected to occur later in this year’s first quarter.
