    中国石化新闻网讯 据OE网站7月6日报道，巴西国家石油公司(Petrobras)排放和气候变化主管在上周五的网络会议上表示，该公司正考虑安装海上装置，以液化所谓的盐下区日益增长的天然气产量。

    Viviana Coelho表示，液化天然气装置可以替代在距海岸100英里以外的深水勘探区生产的石油所产生的天然气。 目前尚不清楚计划中的项目是否有时间表。

    该公司的正式名称为巴西国家石油公司(Petroleo Brasileiro SA)，目前依靠海上管道将海上生产的天然气输送到海岸进行加工。

    巴西国家石油公司表示，缺乏将海上天然气运往海岸的基础设施，可能会限制盐下地区石油产量的上升。

    自发现以来，仅十多年间，被困在大西洋海底一层厚厚盐层之下的油藏，已为巴西提供了超过65％的石油产量。 预计该比率将继续上升。

    一小部分天然气通过平台上的燃烧系统燃烧。

    Coelho在报告中表示，巴西有严格的立法来限制燃烧，而巴西国油希望到2030年将常规燃烧的排放量减少到零。

    她称，燃烧天然气会释放甲烷，巴国油的目标是到2025年将公司的温室气体排放量减少30%-50%。

    根据巴西石油监管机构的数据，这家巴西公司5月份使用了97.6%的天然气。巴国油表示，为了控制储层压力，增加石油产量，有很大一部分被注入地下。

    Petrobras Considers LNG Units for Pre-salt's Natural Gas

    Brazilian state-controlled oil company Petrobras is considering installing offshore units to liquefy the growing natural gas production from the so-called pre-salt area, the company's emissions and climate change manager said during a webinar on Friday.

    Liquefied natural gas units could be an alternative for the gas associated with oil produced at the deep-water exploratory region located more than 100 miles off the coast, said Viviana Coelho. It was unclear if a projected program has a timeframe.

    Petroleo Brasileiro SA, as the firm is formally known, currently relies on offshore pipelines to bring natural gas produced offshore to the coast for processing.

    Lack of infrastructure to ship offshore natural gas to the coast is seen as a possible limitation for rising oil production at the pre-salt, Petrobras has said.

    The reservoirs, where oil is trapped beneath a thick layer of salt in the Atlantic seabed, have supplied more than 65% of Brazil's production in just over a decade since their discovery. The rate is expected to keep rising.

    A small portion of the gas is burned through flaring systems at the platforms.

    Brazil has strict legislation to limit flaring, and Petrobras wants to reduce its routine flaring emissions to zero by 2030, Coelho said in the presentation.

    Flaring releases methane, and Petrobras aims to reduce the company's greenhouse gas emissions by 30% to 50% by 2025, she said.

    The Brazilian company used 97.6% of its natural gas in May, according to Brazil's oil regulator. A significant portion is reinjected into the ground to control reservoir pressure and increase oil production, Petrobras said.
