美国能源信息署 (EIA) 报告称，根据 Enverus Drillinginfo 的数据，2023 年美国伴生溶解天然气或伴生天然气产量与 2022 年相比增长 7.9%，去年平均为 171 亿立方英尺/天。伴生天然气产量是由主要生产石油的井生产的天然气，主要来自美国五大产油区——二叠纪、巴肯、鹰福特、阿纳达科和尼奥布拉拉。

2023 年美国创纪录的原油产量产生了大量伴生天然气。2023 年，西德克萨斯州和新墨西哥州东南部的二叠纪盆地占美国原油产量的 46%，去年是美国伴生天然气产量的最大来源，产量为 115 亿立方英尺/天。2023 年，美国伴生天然气总产量的约三分之二来自二叠纪地区，与 2022 年类似。

2023 年，北达科他州巴肯地区共产出 23 亿立方英尺/天伴生气，占该地区天然气总产量的 70%，是五个产油区中最大的份额。德克萨斯州南部的鹰福特地区是 18 亿立方英尺/天伴生气的来源，而 2023 年中部大陆的尼奥布拉勒和阿纳达科地区共产出 15 亿立方英尺/天伴生气。

2023 年伴生天然气占美国天然气产量的 36.7%，而 2022 年这一比例为 37.4%。非伴生天然气是从主要生产天然气的井中生产的天然气。EIA 将油井定义为气油比 (GOR) 小于或等于每生产一桶石油 6.0 千立方英尺天然气的井。EIA 将 GOR 大于 6.0 千立方英尺/桶的井归类为天然气井。伴生天然气产量的增长速度与干天然气产量相当。

伴生气含有乙烷、丁烷和丙烷等天然气厂液体 (NGPL)。伴生气有时被称为湿气，因为它必须在天然气加工厂进行处理以去除杂质和液体，然后才能销售。伴生气的增加导致乙烷产量创下纪录，乙烷被用作生产塑料、纤维和其他产品的原料。

EIA: US associated natural gas production increased nearly 8% in 2023

The US Energy Information Administration (EIA) has reported that US production of associated-dissolved natural gas, or associated natural gas, increased 7.9% in 2023 compared with 2022, averaging 17.1 billion f3/d last year, according to data from Enverus Drillinginfo. Associated natural gas production, which is natural gas produced by wells that predominantly produce oil, comes mainly from five major oil-producing regions in the United States – the Permian, Bakken, Eagle Ford, Anadarko, and Niobrara.

Record US crude oil production in 2023 generated large volumes of associated natural gas. The Permian Basin in West Texas and southeastern New Mexico accounted for 46% of U.S. crude oil production in 2023 and was the largest source of US associated gas production last year at 11.5 billion f3/d. In 2023, around two-thirds of total US associated natural gas production came from the Permian region, similar to 2022.

In 2023, 2.3 billion f3/d of associated gas was produced in North Dakota’s Bakken region, which accounted for 70% of the region’s total natural gas production – the largest share among the five oil-producing regions. The Eagle Ford region in southern Texas was the source of 1.8 billion f3/f of associated gas, while a combined 1.5 billion f3/d of associated gas was produced in the Niobrara and Anadarko regions in the midcontinent in 2023.

Associated natural gas accounted for 36.7% of U.S. natural gas production in 2023, compared with 37.4% in 2022. Non-associated natural gas is natural gas produced from wells that predominantly produce natural gas. EIA defines oil wells as those with a gas-to-oil ratio (GOR) of less than or equal to 6.0 thousand f3 of natural gas per bbl of oil produced. EIA classifies wells with a GOR of more than 6.0 thousand f3/bbl as natural gas wells. Associated natural gas production has grown at a rate commensurate with dry natural gas production.

Associated gas contains natural gas plant liquids (NGPLs) such as ethane, butane, and propane. Associated gas is sometimes characterised as wet gas because it must be treated at gas processing plants to remove impurities and liquids before being marketed. The increase in associated gas has led to record ethane production, which is used as a feedstock to produce plastics, fibres, and other products.
