据NS Energy 4月25日消息，BW Energy已决定通过钻探六口生产井，分阶段推进巴西水域的Maromba开发项目。
这些油井将与重新部署的浮式生产储存和卸油装置(FPSO)相连。该项目第一阶段的第一批石油目标是在2025年。
该公司的开发计划已获得巴西石油和天然气监管机构ANP的批准，预计将在适当时候获得巴西环境与可再生自然资源研究所（IBAMA）的全面环保批准。
BW Energy已签署协议，以5000万美元从BW Offshore收购FPSO Polvo，用于Maromba项目。
FPSO Polvo将在位于坎波斯盆地南部的巴西近海油田进行升级和重新部署。它将设计用于多达10口生产井，存储容量为120万桶。
FPSO的总液体容量将为每天85000桶。其石油生产能力将为每天65000桶，而水处理能力预计为每天75000桶。
BW Energy于2019年以1.15亿美元从巴西国家石油公司和雪佛龙公司手中收购了Maromba油田。
BW Energy表示，Maromba开发项目的投资决策将取决于如项目融资完成等一些先决条件。
据该公司称，第一阶段将钻探三口井。随后将在2027年进行第二次钻探活动，再增加三口井。
根据初步估计，第一阶段的开发可能涉及近4亿美元的投资。
BW Energy首席执行官Carl Arnet表示：“自2019年收购以来以及疫情期间，我们一直致力于优化Maromba的发展计划。这包括技术评估、地质、地震和油井数据的全谱分析，以及广泛的储层建模和模拟。
“根据我们的调查结果，我们决定继续开发与FPSO相连的六口水平生产井，为我们的利益相关者释放大量石油生产和长期价值创造。”
BW Energy表示，分阶段开发Maromba油田将有助于更好地监测储层并优化第二个钻井计划。
该公司预计，该油田的石油产量峰值将在每天30000-40000桶之间。
经公司技术评估，确定前三口井不需要注水。然而，BW Energy表示，剩余三口井的钻探是一种意外情况。

BW Energy to develop Maromba field, offshore Brazil in two phases
BW Energy has decided to move ahead with the Maromba development project in Brazilian waters in a phased manner through the drilling of six production wells.
The wells will be tied back to a redeployed floating production storage and offloading (FPSO). First oil from the project through phase 1 is targeted in 2025.
The company’s development plan has been approved by the Brazilian oil and gas regulator ANP and full environmental approval from the Brazilian Institute of the Environment and Renewable Natural Resources (IBAMA) is expected to be obtained in due course.
BW Energy has signed a deal to acquire FPSO Polvo from BW Offshore for $50m for using the vessel for the Maromba project.
FPSO Polvo will be upgraded and redeployed on the offshore Brazilian field, located in the southern part of the Campos Basin. It will be designed for up to 10 production wells with a storage capacity of 1.2 million barrels.
The FPSO’s total liquid capacity will be 85,000 barrels per day. Its oil production capacity will be 65,000 barrels per day, while the water treatment capacity is expected to be 75,000 barrels per day.
The Maromba field was acquired by BW Energy in 2019 for $115m from Petrobras and Chevron.
The investment decision on the Maromba development project will be subject to some preceding conditions such as completion of the project financing, said BW Energy.
According to the company, the first phase will see the drilling of three wells. This will be followed by a second drilling campaign with an additional three wells in 2027.
based on preliminary estimates, the phase 1 development could involve an investment of nearly $400m.
BW Energy CEO Carl Arnet said: “We have worked to optimise the Maromba development plan since the acquisition in 2019 and during the Covid-19 pandemic. This includes technical evaluations, full-spectrum analysis of geological, seismic and well data, as well as extensive reservoir modelling and simulations.
“based on our findings, we have decided to proceed with a development with six horizontal production wells connected to a FPSO to unlock significant oil production and long-term value generation for our stakeholders.”
BW Energy said that developing the Maromba field in stages will allow for better reservoir monitoring and optimisation of the second drilling programme.
The company expects the peak oil production from the field to be in the range of 30,000-40,000 barrels per day.
Following a technical evaluation by the company, it was determined that water injection is not needed for the first three wells. However, it is a contingency for the drilling of the remaining three wells, said BW Energy.
