據美國鉆井網站2022年7月31日報道，新加坡杰德斯通石油天然氣公司日前同意收購英國石油公司（bp）在澳大利亞西北部北卡納文盆地的4個油田的全部16.67%的開采權益。這4個海上油田分別是Cossack、Wanaea、Lambert和Hermes油田。

這些也被稱為西北大陸架石油項目的海上油田由伍德賽德能源公司運營。這個項目包括13口水下油井，通過“奧克哈號” FPSO船進行生產。

這艘FPSO船在2011年安裝在這4個油田，具有60000桶/天的原油處理能力，以及水處理、天然氣處理和回注設施。Cossack、Wanaea和Hermes油田目前正在生產，預計2P總儲量為3030萬桶。

2021年，這些油田的平均日總產量為12461桶，2022年第一季度的平均日產量為14178桶。  

這些油田還生產伴生天然氣，西北大陸架石油項目的合作伙伴有權使用這些伴生天然氣為“奧克哈號”FPSO船提供燃料，其余的伴生天然氣用作西北大陸架液化天然氣項目的原料。

據悉，杰德斯通石油天然氣公司估計擁有8.9億桶原油儲量，這為進一步投資提高原油采收率提供了機會。 

這筆交易以資產購買的形式進行，包括bp在Cossack、Wanaea、Lambert和Hermes 4個油田16.67%的開采權益、海底基礎設施、“奧克哈號”FPSO船以及放棄債務。

BP Sells Stake In Oil Fields Off Australia To Jadestone 

Oil and gas company Jadestone has agreed to acquire BP’s entire 16.67 percent working interest in the Cossack, Wanaea, Lambert, and Hermes oil fields in the North Carnarvon basin offshore north-west Australia.

The fields, also known as the North West Shelf Oil Project, are operated by Woodside Energy. The project comprises 13 subsea wells producing through the Okha FPSO vessel.

The FPSO was installed at the fields in 2011 and has 60,000 bpd of oil processing capacity, along with water handling and gas processing, and reinjection facilities. The Cossack, Wanaea, and Hermes fields are currently in production and are estimated to contain aggregate gross 2P reserves of 30.3 mmbbls.

Gross average production from the fields in 2021 was 12,461 bpd with the first quarter of 2022 production averaging 14,178 bpd gross.

The fields also produce associated gas, with the partners in the North West Shelf Oil Project having the rights to use the gas required to fuel the Okha FPSO, with the remainder being used as feedstock in the North West Shelf LNG project.

The four fields are mid-life producing assets with significant original oil in place, which Jadestone estimates at approximately 890 mmbbls, and which provides the opportunity for further investment to increase recovery factors.

The transaction is structured as an asset purchase, which includes BP’s 16.67 percent working interest in the Cossack, Wanaea, Lambert, and Hermes fields, subsea infrastructure, FPSO, and abandonment liabilities.
