Project introduction

The field contains high-quality crude oil with low sulphur content and API gravity of approximately 31o. It has estimated recoverable reserves of more than two billion barrels of oil equivalent (Bboe). The BM-S-8 licence area has recoverable volumes of approximately 700 million to 1,300 million boe from Bacalhau and additional exploration prospects.

development details

The Bacalhau oil field development will involve the development of 19 wells and the installation of 130km of flowlines and rigid risers and 35km of umbilicals. A new floating production storage and offloading (FPSO) vesselwill be deployed at the field to produce oil. It will be permanently moored by a spread mooring system.

MODEC’s M350 hull, a next-generation hull for FPSOs, will be utilised for the vessel. To be built in China, the vessel will have a full double hull design that will be able to accommodate bigger topsides and provide enhanced storage capacity and service life.

The topside modules of the FPSO will weigh approximately 20,000t. TheFPSOwill have the production capacity of up to 220,000 barrels of crude oil a day. It will produce and inject up to 530 million standard cubic feet (Mmscf) of associated gas per day, and inject up to 200,000 barrels of seawater each day to maintain pressure in the formation. The minimum crude oil storage capacity of the FPSO will be two million barrels.

Contractors involved

MODEC was contracted for the design and construction of the FPSO vessel in January 2020. The company secured the contract after successful execution of the pre-front end engineering design (Pre-FEED) contract received in December 2018. The mooring system for the FPSO will be supplied by SOFEC, a subsidiary of MODEC Group.

Aibel signed a letter of intent (LOI) with MODEC for the FEED phase of the vessel covering management and basic engineering services. The LOI includes an option for an engineering, procurement and construction (EPC) contract for the topside modules for the FPSO.

Equinor contracted Subsea Integration Alliance, a strategic alliance between Subsea 7 and Schlumberger’s OneSubsea division, to conduct FEED study on the Bacalhau field.

埃克森美孚ExxonMobil (40%)

巴西石油Petrogal Brasil (20%)

运营方

挪威国家石油公司Equinor

项目简介

该油田蕴藏低硫优质原油,API重力指标约30,预计可采储量超过20亿桶石油当量。 BM-S-8许可区可从Bacalhau油田开采约7亿至13亿桶油当量,并可开展其他勘探活动。

油田开发

Bacalhau油田将开发19口钻井,并安装130km输油管线和刚性立管,以及35km脐带管。

现场将部署一艘新的浮式生产储卸油船(FPSO)进行采油,将该船通过扩展系泊系统永久系泊。MODEC公司为此船配备用于FPSO的下一代新型船体——“ M350船体”。该船将在中国制造,采用全双船体设计,具有更大的顶部、更大的存储能力和使用寿命。

FPSO顶部模块重量约2万吨,日产能将达22万桶原油。它将每天生产和注入多达5.3亿标准立方英尺(Mmscf)的伴生气,并每天注入20万桶海水以维持地层压力。 FPSO的最低原油储存能力为200万桶。

承包商

MODEC于2018年12月被授予FPSO的前端工程设计(Pre-FEED)合同,由于其成功执行Pre-FEED合同,现已被选为总包承包商。

挪威石油服务公司(Aibel)与MODEC签署了该船FEED阶段的意向书(LOI),内容涵盖项目管理与基本工程服务。 意向书中设置可以选择执行FPSO顶部模块的工程设计、采购和建造(EPC)。

为在Bacalhau油田开展FEED研究,挪威国家石油公司(Equinor)与海底七公司(Subsea 7)签署了“海底一体化联盟”协议,该联盟是海底七公司(Subsea 7)与斯伦贝谢(Schlumberger)子公司One Subsea结成的战略联盟。
