道达尔能源公司10 月 30 日宣布，在Mero-2 投产不到一年后，巴西海上 Mero 油田的第三开发阶段 Mero-3 已产出第一批石油。

Mero-3 位于桑托斯盆地里约热内卢海岸 180 公里外的 Libra 区块，包括 15 口与 Marechal Duque de Caxias FPSO 相连的油井，日产油量为 18 万桶。随着 Mero-3 的投产，Mero 油田的整体日产油量将达到 59 万桶。

Mero-3 的设计目标是将温室气体排放降至最低，将伴生气重新注入油藏，并且不进行常规燃烧。该项目的 FPSO 稍后将与 HISEP 试点项目相连。目前正在开发的试点项目将在海底将石油与富含二氧化碳的气体分离，并将气体直接重新注入油藏。

Mero-4 是额外开发阶段，产量为 180,000 桶/天，目前正在建设中，预计将于 2025 年投产。

巴西国家石油公司是梅罗油田的运营商，拥有 38.6% 的股份。道达尔能源公司和 壳牌 巴西公司各拥有 19.3% 的股份， 中石油 和 中海油 各拥有 9.65% 的股份。Pr茅Sal Petroleo SA 持有剩余的 3.5%。

Less than a year after the startup of Mero-2, the third development phase of the Mero field offshore Brazil, Mero-3, has produced first oil, TotalEnergies announced Oct. 30.

Located in the Libra block, 180 km off the coast of Rio de Janeiro, in the Santos Basin, Mero-3 includes 15 wells connected to the Marechal Duque de Caxias FPSO, with a production capacity of 180,000 bbl/d of oil. With the start-up of Mero-3, the overall production capacity of the Mero field will reach 590,000 bbl/d.

Mero-3 was designed to minimize greenhouse gas emissions, with reinjection of the associated gas into the reservoir and zero routine flaring. The project’s FPSO will later be connected to the HISEP pilot project. Currently under development, the pilot project will separate oil from CO2-rich gas at the bottom of the ocean and reinject the gas directly into the reservoir.

Mero-4, an additional development phase of 180,000 bbl/d, is currently under construction, with start-up expected in 2025.

Petrobras is the operator of the Mero field with a 38.6% stake. TotalEnergies and Shell Brasil each hold a 19.3% and CNPC and CNOOC each have a 9.65% stake in the field. Pré-Sal Petróleo SA holds the remaining 3.5%.
