據油價網2021年6月25日報道，美國能源信息署(EIA)周五表示，今年迄今為止，美國運營商已經完成、開始建設或宣布了19個石油和天然氣管道項目。

　　EIA液體管道項目數(shù)據庫的最新數(shù)據顯示，今年到目前為止，美國已經有兩條液體管道竣工，17個液體管道項目正處于建設階段或已宣布。

　　在19條石油液體管道項目中，12個是原油項目，6個是液態(tài)烴天然氣液體項目（HGLs），1個是運輸石油產品項目。 在這19個項目中，有10個項目是新建管道，7個項目是現(xiàn)有系統(tǒng)的擴展或延長，2個項目是管道上進行貨物轉換。

　　去年，美國完成了24個石油液體管道項目，其中包括11個原油項目、12個HGL項目和1個石油產品項目。 EIA的數(shù)據顯示，美國去年年共有11個項目是新建管道項目，另有11個項目是現(xiàn)有系統(tǒng)的擴建項目。

　　根據EIA的數(shù)據，完成石油液體管道項目的歷史最高紀錄是2014年，共完成了多達35個項目，2019年完成了30個項目。

　　2019年，二疊紀盆地大量原油管道產能上線，將該盆地激增的原油產量轉移到煉油中心和出口終端。

　　EIA 6月早些時候說，近幾個月美國有更多的天然氣管道進入服務，把天然氣從二疊紀盆地輸送到墨西哥，增加美國天然氣出口到美國南部的鄰居以及減少天然氣在美國德州瓦哈中心交易的大折扣。

　　天然氣管道輸送能力的增加提高了瓦哈中心的天然氣價格，縮小了西德克薩斯州天然氣價格相對于美國亨利中心基準價格的折扣。

　　在2020年危機之前的幾年里，由于管道限制和壓縮站偶爾出現(xiàn)技術問題，瓦哈中心的天然氣價格有時甚至會出現(xiàn)負值。

　　19 U.S. Oil & Gas Pipelines Moving To Completion This Year

　　U.S. operators have completed, started building, or announced a total of 19 petroleum liquids pipeline projects so far this year, the Energy Information Administration (EIA) said on Friday.

　　Two pipelines have already been completed so far in 2021, while 17 projects are either in the construction stage or announced, according to the latest data in EIA’s Liquids Pipeline Projects Database.

　　Of the 19 petroleum liquids pipelines, 12 are crude oil projects, six are hydrocarbon gas liquids (HGLs) projects, and one project is for carrying petroleum products. Ten out of the 19 projects are new pipelines, 7 projects are expansions or extensions of existing systems, and 2 projects are conversions of the commodity carried on the pipeline.

　　Last year, the U.S. saw a total of 24 petroleum liquids pipeline projects completed, including 11 crude oil projects, 12 HGL projects, and 1 petroleum product project. In 2020, a total of 11 projects were new pipelines, and another 11 projects were expansions of existing systems, the EIA data showed.

　　The record year for petroleum liquids pipelines was 2014, when as many as 35 projects were completed, followed by 30 projects completed in 2019, according to the EIA data.

　　In 2019, a lot of crude pipeline capacity came online in the Permian basin to take away surging crude production in the basin to refining hubs and export terminals.

　　More natural gas pipelines have entered into service in recent months to carry gas from the Permian basin to Mexico, boosting U.S. gas exports to America’s neighbor to the south and reducing the wide discount at which gas is traded at the Waha Hub in Texas, the EIA said earlier this month.

　　The increased gas pipeline takeaway capacity raised the gas prices at the Waha Hub and narrowed the discount of the gas price in West Texas to the U.S. benchmark at Henry Hub.

　　In the years before the 2020 crisis, prices at the Waha Hub even flipped to negative at times amid pipeline constraints and occasional issues at compressor stations.
