据美国钻井网站2022年7月31日报道，新加坡杰德斯通石油天然气公司日前同意收购英国石油公司（bp）在澳大利亚西北部北卡纳文盆地的4个油田的全部16.67%的开采权益。这4个海上油田分别是Cossack、Wanaea、Lambert和Hermes油田。

这些也被称为西北大陆架石油项目的海上油田由伍德赛德能源公司运营。这个项目包括13口水下油井，通过“奥克哈号” FPSO船进行生产。

这艘FPSO船在2011年安装在这4个油田，具有60000桶/天的原油处理能力，以及水处理、天然气处理和回注设施。Cossack、Wanaea和Hermes油田目前正在生产，预计2P总储量为3030万桶。

2021年，这些油田的平均日总产量为12461桶，2022年第一季度的平均日产量为14178桶。  

这些油田还生产伴生天然气，西北大陆架石油项目的合作伙伴有权使用这些伴生天然气为“奥克哈号”FPSO船提供燃料，其余的伴生天然气用作西北大陆架液化天然气项目的原料。

据悉，杰德斯通石油天然气公司估计拥有8.9亿桶原油储量，这为进一步投资提高原油采收率提供了机会。 

这笔交易以资产购买的形式进行，包括bp在Cossack、Wanaea、Lambert和Hermes 4个油田16.67%的开采权益、海底基础设施、“奥克哈号”FPSO船以及放弃债务。

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.
