据离岸工程网站8月25日消息 石油和天然气公司BW能源在加蓬近海Dussafu区块的Hibiscus North探井（DHBNM-1）中发现了石油，但其规模估计将不得不等到钻探完成。
其位于Hibiscus发现井DHIBM-1东北偏北约6千米处，水深约115米，计划总深度约为3500米。
BW能源表示：“预计该发现将增加先前公布的该区块已发现可采资源总量估计，目前估计约为1.05亿桶。”
BW能源公司于2021年7月28日宣布开钻该井。
据该公司称，在Hibiscus North的钻井作业期间，在2794米深处遇到了甘巴储层，在上甘巴砂岩中遇到了约13.5米的含油储层。
该公司表示：“整个油气柱的确定有待于裸眼电缆测井作业，该作业将在钻井至计划总深度后进行。”
Borr Norve自升式钻井平台正在继续钻井作业，以便与更深的Dentale地层中的探井次级目标相交。
达到总深度后，将进行测井作业和石油发现评估，随后将钻探侧钻，以圈定油田。Dussafu区块面积为850平方公里。BW能源为运营商，持有区块73.5%的权益。Panoro能源持有17.5%的权益，加蓬石油公司持有9%。
2021年Dussafu区块的总产量预计为约12800桶/天，2020年的平均产量为14100桶/天。

BW Energy Finds Oil Offshore Gabon
Oil and gas firm BW Energy has made an oil find in the Hibiscus North exploration well (DHBNM-1) in the Dussafu Block, offshore Gabon, but the size estimate will have to wait until the drilling has been completed.
The well is located approximately 6 km north-northeast of the Hibiscus discovery well DHIBM-1 in approximately 115 meters of water depth. The well will be drilled to a planned total depth of approximately 3500m.
The well is located about six kilometers north-northeast of the Hibiscus discovery well DHIBM-1, in a water depth of around 115 meters. The well will be drilled to a total depth of about 3500 meters.
"It is expected that the discovery will add to the previously announced gross discovered recoverable resource estimate for the block, which is currently estimated to be approximately 105 million barrels gross," BW Energy said.
BW Energy announced the spudding of the well align="justify"> According to the company, during the drilling operations at Hibiscus North, the Gamba [reservoir] was encountered at a depth of 2794 meters and encountered approximately 13.5m of oil-bearing reservoir in the Upper Gamba sandstone.
"Determination of the overall hydrocarbon column is pending open hole wireline logging operations which will be conducted after drilling the well to the planned total depth," the company said.
The Borr Norve Jack-up is continuing drilling operations to intersect the secondary targets for the exploration well in the deeper Dentale Formation.
After reaching total depth, logging operations and evaluation of the oil discovery will be carried out, which will be followed by the drilling of a side-track to delineate the field. The Dussafu Block is 850 square km. BW Energy is the operator and holds 73.5% interest in the block. Panoro Energy holds 17.5% interest and the Gabonese Oil Company holds 9%.
Total Dussafu area output for 2021 is projected to be ~12,800 barrels per day (gross), compared to 14,100 barrels per day on average in 2020.
