據(jù)NS Energy 4月25日消息，BW Energy已決定通過鉆探六口生產(chǎn)井，分階段推進(jìn)巴西水域的Maromba開發(fā)項(xiàng)目。

這些油井將與重新部署的浮式生產(chǎn)儲(chǔ)存和卸油裝置(FPSO)相連。該項(xiàng)目第一階段的第一批石油目標(biāo)是在2025年。

該公司的開發(fā)計(jì)劃已獲得巴西石油和天然氣監(jiān)管機(jī)構(gòu)ANP的批準(zhǔn)，預(yù)計(jì)將在適當(dāng)時(shí)候獲得巴西環(huán)境與可再生自然資源研究所（IBAMA）的全面環(huán)保批準(zhǔn)。

BW Energy已簽署協(xié)議，以5000萬美元從BW Offshore收購FPSO Polvo，用于Maromba項(xiàng)目。

FPSO Polvo將在位于坎波斯盆地南部的巴西近海油田進(jìn)行升級和重新部署。它將設(shè)計(jì)用于多達(dá)10口生產(chǎn)井，存儲(chǔ)容量為120萬桶。

FPSO的總液體容量將為每天85000桶。其石油生產(chǎn)能力將為每天65000桶，而水處理能力預(yù)計(jì)為每天75000桶。

BW Energy于2019年以1.15億美元從巴西國家石油公司和雪佛龍公司手中收購了Maromba油田。

BW Energy表示，Maromba開發(fā)項(xiàng)目的投資決策將取決于如項(xiàng)目融資完成等一些先決條件。

據(jù)該公司稱，第一階段將鉆探三口井。隨后將在2027年進(jìn)行第二次鉆探活動(dòng)，再增加三口井。

根據(jù)初步估計(jì)，第一階段的開發(fā)可能涉及近4億美元的投資。

BW Energy首席執(zhí)行官Carl Arnet表示：“自2019年收購以來以及疫情期間，我們一直致力于優(yōu)化Maromba的發(fā)展計(jì)劃。這包括技術(shù)評估、地質(zhì)、地震和油井?dāng)?shù)據(jù)的全譜分析，以及廣泛的儲(chǔ)層建模和模擬。

“根據(jù)我們的調(diào)查結(jié)果，我們決定繼續(xù)開發(fā)與FPSO相連的六口水平生產(chǎn)井，為我們的利益相關(guān)者釋放大量石油生產(chǎn)和長期價(jià)值創(chuàng)造。”

BW Energy表示，分階段開發(fā)Maromba油田將有助于更好地監(jiān)測儲(chǔ)層并優(yōu)化第二個(gè)鉆井計(jì)劃。

該公司預(yù)計(jì)，該油田的石油產(chǎn)量峰值將在每天30000-40000桶之間。

經(jīng)公司技術(shù)評估，確定前三口井不需要注水。然而，BW Energy表示，剩余三口井的鉆探是一種意外情況。

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.
