巴國油考慮將LNG裝置用于鹽下層天然氣

據OE網站7月6日報道，巴西國家石油公司(Petrobras)排放和氣候變化主管在上周五的網絡會議上表示，該公司正考慮安裝海上裝置，以液化所謂的鹽下區(qū)日益增長的天然氣產量。

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)生產的石油所產生的天然氣。 目前尚不清楚計劃中的項目是否有時間表。

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

巴西國家石油公司表示，缺乏將海上天然氣運往海岸的基礎設施，可能會限制鹽下地區(qū)石油產量的上升。

自發(fā)現以來，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65％的石油產量。 預計該比率將繼續(xù)上升。

一小部分天然氣通過平臺上的燃燒系統(tǒng)燃燒。

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

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

根據巴西石油監(jiān)管機構的數據，這家巴西公司5月份使用了97.6%的天然氣。巴國油表示，為了控制儲層壓力，增加石油產量，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.
