BW Energy于2023年4月10日(星期一)宣布了加蓬近海Dussafu许可证中Hibiscus/Ruche一期开发项目的第一批石油。该公司解释说，第一口井的生产表现符合预期，目前稳定在约6000桶/日。
值得提醒的是，由于Borr Drilling为其钻井计划雇佣的Norve自升式钻井平台的时间表可能发生变化，Hibiscus/Ruche开发项目的第一批石油的时间表被推迟到了去年2023年第一季度末，而不是之前预计的2022年底。
2023年4月初，该公司确认Hibiscus/Ruche一期开发活动的第一口生产井DHIBM-3H井的钻井和完井作业已经完成。根据BW Energy当时的声明，第一批石油预计将在4月初，而新的气举压缩机的调试和启动将在FPSO上的第一批石油活动之后进行。
据BW Energy称，DHIBM-3H井是从BW MaBoMo生产设施钻到Hibiscus油田Gamba砂岩储层3883米深处的。钻井作业在生产设施、立管和管道安装后的年初开始。Hibiscus/Ruche生产的石油通过管道运输至FPSO BW Adolo进行处理和储存，然后再卸载至油轮。
BW Energy首席执行官Carl Krogh Arnet评论道：“我们以出色的HSE表现如期从Hibiscus/Ruche交付了第一批石油。这是加蓬在2023年至2024年初完成钻井计划和资产升级过程中实现连续产量增长的第一步。”
BW Energy在加蓬附近的Hibiscus/Ruche开发项目位于Tortue油田西北约20公里处，目标是Hibiscus和Ruche油田。最初，该项目需要在一个12口井的分阶段计划中钻探多达6口水平生产井，该计划将与一个生产设施相连。这六口井中的四口井将瞄准芙蓉油田，其余两口井将对准鲁切油田。
该公司概述，Hibiscus/Ruche 1期钻井活动的目标是四口Hibiscus Gamba和两口Ruche Gamba井，预计2024年初所有井完工后，这两口井的总石油产量将增加约30000桶/日。这些井是由Borr Drilling公司的Norve自升式钻机开采的。
另一方面，BW Energy强调，浮式生产储油船BW Adolo上的气举压缩机安装工作正在进行中，重点是在Hibiscus/Ruche的第一批石油之后进行调试和启动，这在浮式生产油生产储油船上的高活动期具有优先权。
Carl K.Arnet总结道：“我们现在的首要任务是完成启动活动，稳定DHIBM-3H井的生产。与此同时，新的气举压缩机的启动工作正在进行，以支持现有六口Tortue井的生产，同时也按计划推进下一口Hibiscus/Ruche生产井的钻探。”。

Oslo-listed oil and gas E&P company BW Energy has achieved the first oil from its first well in a multi-well drilling campaign offshore Gabon.

BW Energy announced the first oil from the Hibiscus/Ruche Phase 1 development in the Dussafu licence offshore Gabon on Monday, 10 April 2023. The company explains that the production performance from the first well has been in line with expectations and is currently stabilised at approximately 6,000 barrels per day.
As a reminder, the timeline for the first oil from the Hibiscus/Ruche development was bumped to the end of the first quarter of 2023 last year, rather than the previously anticipated date in late 2022, due to a potential change in the schedule of Borr Drilling’s Norve jack-up rig, which the firm hired for its drilling programme.
At the start of April 2023, the company confirmed the drilling and completion operations on the first production well of the Hibiscus/Ruche Phase 1 development campaign, DHIBM-3H well, were completed. Based on BW Energy’s statement at the time, the first oil was expected in early April while the commissioning and start-up of the new gas lift compressor would follow the first oil activities on the FPSO.
According to BW Energy, the DHIBM-3H well was drilled from the BW MaBoMo production facility to a depth of 3,883 metres into Gamba sandstone reservoir on the Hibiscus field . The drilling operations started at the start of the year following the installation of the production facility, risers, and pipelines. The oil produced at Hibiscus/Ruche is transported by pipeline to the FPSO BW Adolo for processing and storage before offloading to oil tankers.
Carl Krogh Arnet , the CEO of BW Energy, commented: “We delivered first oil from Hibiscus/Ruche on schedule with an excellent HSE performance. This represents the first of several steps on a path for successive production growth in Gabon as we complete the drilling programme and asset upgrades through 2023 and into early 2024.”
Located approximately 20 kilometres northwest of the Tortue field, BW Energy’s Hibiscus/Ruche development project off Gabon targets the Hibiscus and Ruche fields. Initially, this project entails the drilling of up to six horizontal production wells in a 12-well phased programme, which will be connected to a production facility. Four of these six wells will target the Hibiscus field while the remaining two will target the Ruche field.
The company outlines that the Hibiscus/Ruche Phase 1 drilling campaign targets four Hibiscus Gamba and two Ruche Gamba wells, which are expected to add approximately 30,000 barrels per day of total oil production when all wells are completed in early 2024. The wells are drilled by Borr Drilling’s Norve jack-up rig.
On the other hand, BW Energy highlights that the installation of the gas lift compressor is ongoing on the FPSO BW Adolo with a focus on commissioning and start-up following the first oil from Hibiscus/Ruche, which had priority during the high-activity period onboard the FPSO.
“Our priority now is to complete start-up activities and stabilise production from the DHIBM-3H well. In parallel, work progresses towards start-up of the new gas lift compressor to support production from the existing six Tortue wells while also moving ahead with drilling of the next Hibiscus/Ruche production wells as planned,” concluded Carl K. Arnet.
