据油价网2021年6月25日报道，美国能源信息署(EIA)周五表示，今年迄今为止，美国运营商已经完成、开始建设或宣布了19个石油和天然气管道项目。
EIA液体管道项目数据库的最新数据显示，今年到目前为止，美国已经有两条液体管道竣工，17个液体管道项目正处于建设阶段或已宣布。
在19条石油液体管道项目中，12个是原油项目，6个是液态烃天然气液体项目（HGLs），1个是运输石油产品项目。 在这19个项目中，有10个项目是新建管道，7个项目是现有系统的扩展或延长，2个项目是管道上进行货物转换。
去年，美国完成了24个石油液体管道项目，其中包括11个原油项目、12个HGL项目和1个石油产品项目。 EIA的数据显示，美国去年年共有11个项目是新建管道项目，另有11个项目是现有系统的扩建项目。
根据EIA的数据，完成石油液体管道项目的历史最高纪录是2014年，共完成了多达35个项目，2019年完成了30个项目。
2019年，二叠纪盆地大量原油管道产能上线，将该盆地激增的原油产量转移到炼油中心和出口终端。
EIA 6月早些时候说，近几个月美国有更多的天然气管道进入服务，把天然气从二叠纪盆地输送到墨西哥，增加美国天然气出口到美国南部的邻居以及减少天然气在美国德州瓦哈中心交易的大折扣。
天然气管道输送能力的增加提高了瓦哈中心的天然气价格，缩小了西德克萨斯州天然气价格相对于美国亨利中心基准价格的折扣。
在2020年危机之前的几年里，由于管道限制和压缩站偶尔出现技术问题，瓦哈中心的天然气价格有时甚至会出现负值。

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.
