巴國(guó)油考慮將LNG裝置用于鹽下層天然氣

據(jù)OE網(wǎng)站7月6日?qǐng)?bào)道，巴西國(guó)家石油公司(Petrobras)排放和氣候變化主管在上周五的網(wǎng)絡(luò)會(huì)議上表示，該公司正考慮安裝海上裝置，以液化所謂的鹽下區(qū)日益增長(zhǎng)的天然氣產(chǎn)量。

Viviana Coelho表示，液化天然氣裝置可以替代在距海岸100英里以外的深水勘探區(qū)生產(chǎn)的石油所產(chǎn)生的天然氣。 目前尚不清楚計(jì)劃中的項(xiàng)目是否有時(shí)間表。

該公司的正式名稱為巴西國(guó)家石油公司(Petroleo Brasileiro SA)，目前依靠海上管道將海上生產(chǎn)的天然氣輸送到海岸進(jìn)行加工。

巴西國(guó)家石油公司表示，缺乏將海上天然氣運(yùn)往海岸的基礎(chǔ)設(shè)施，可能會(huì)限制鹽下地區(qū)石油產(chǎn)量的上升。

自發(fā)現(xiàn)以來(lái)，僅十多年間，被困在大西洋海底一層厚厚鹽層之下的油藏，已為巴西提供了超過(guò)65％的石油產(chǎn)量。 預(yù)計(jì)該比率將繼續(xù)上升。

一小部分天然氣通過(guò)平臺(tái)上的燃燒系統(tǒng)燃燒。

Coelho在報(bào)告中表示，巴西有嚴(yán)格的立法來(lái)限制燃燒，而巴西國(guó)油希望到2030年將常規(guī)燃燒的排放量減少到零。

她稱，燃燒天然氣會(huì)釋放甲烷，巴國(guó)油的目標(biāo)是到2025年將公司的溫室氣體排放量減少30%-50%。

根據(jù)巴西石油監(jiān)管機(jī)構(gòu)的數(shù)據(jù)，這家巴西公司5月份使用了97.6%的天然氣。巴國(guó)油表示，為了控制儲(chǔ)層壓力，增加石油產(chǎn)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.
