据油田技术10月21日报道，Vaalco Energy宣布Etame 9P井，在位于Vaalco运营的加蓬近海Etame油田的entale储层，成功钻探至总深度10，260英尺，遇到了Gamba和Dentale油砂。目前正在进行的是进行较浅深度的作业，并在Gamba油藏Etame 9H水平开发井段进行钻探。
此次作业证实了在2001年钻的Etame 4V井中首次发现的Dentale油柱的存在。遇到了大约35英尺的高质量Dentale油砂，其孔隙率为27%，渗透率为3000 mD。
Vaalco估计，Dentale地下储层中的可采石油总储量在250万桶到1050万桶之间。该公司在Gamba油藏中发现了一个比预期更大的油柱，这可能会导致Etame 9H和Etame 11H井的最终采收率比预期更高。
该公司首席执行官Cary Bounds评论道:“我们很高兴在2019/2020年钻探活动中进行的首次评估，证实了Dentale油田的可采资源有很好的开采潜力。Etame 9P的成功是我们发现的众多有潜力的评估井的其中一个，这有可能为我们的股东创造巨大的价值。这也再次肯定了Etame区域有待开发的巨大潜力。”

VAALCO Energy confirms oil discovery offshore Gabon
VAALCO Energy, Inc. has announced that the Etame 9P appraisal wellbore, targeting the subcropping Dentale reservoir beneath the VAALCO-operated Etame field offshore Gabon, was successfully drilled to a total depth of 10 260 ft and encountered both Gamba and Dentale oil sands. Operations are underway to plug back to a shallower depth and drill the Etame 9H horizontal development well section in the Gamba reservoir.
Verifies the presence of a Dentale oil column first identified in the Etame 4V well drilled in 2001.
Encountered approximately 35 feet of good-quality Dentale oil sands with 27% porosity and 3000 mD of permeability.
VAALCO estimates gross recoverable oil resources of 2.5 to 10.5 million bbl of oil present in subcropping Dentale reservoirs.
Identified an oil column which was thicker than expected in the Gamba reservoir which may result in higher ultimate oil recovery from the planned Etame 9H and Etame 11H wells than previously expected.
Cary Bounds, Chief Executive Officer, commented: “We are excited that our first appraisal wellbore in the 2019/2020 drilling campaign has confirmed our estimates of meaningful recoverable resources in the subcropping Dentale, which we currently have classified as prospective. The successful Etame 9P is the first of many appraisal opportunities that we have identified that have the potential to create substantial organic value for our shareholders. The result reaffirms the upside potential yet to be exploited from the Etame field.
